Ref formula
According to the "Metacharacter" table at AutoWikiBrowser/Regular expression, the less than sign < and the greater than sign > must be "escaped", that is, preceded by a backslash \. However, according to AutoWikiBrowser/Regular expression, several formulas are given that don't escape. When I tried the second of those formulas, ]*>([^<]|<(?!/ref>))+ it works the same with or without escaping. Neither version works very well for its intended purpose of finding references, because it doesn't account for ref names (example: ), so the formula will recognize the first part of a ref name without recognizing its end, including normal prose until it eventually gets to the end of a more normal reference. At the moment I think the solution is to add a front slash to the formula so it will reject ref names, like this: /]*>([^<]|<(?!/ref>))+ and also to remove > and < from the list of characters that must be escaped. While I'm at it, \n for new line doesn't work on Wikipedia. Is anybody still reading this talk page? Art LaPella (talk) 06:13, 22 March 2010 (UTC)

Using Groups
Can anyone please teach me how to use groups? I don't understand how to use $1, $2, $3, etc. For example if I have a string like:

prefix|word1|word2|suffix

then how can I transform it into

prefix|word2|word1|suffix

I allways have the same prefix and suffix, that would make the script easier, I think.

thanks Ark25 (talk) 20:56, 30 April 2010 (UTC)


 * I found it:
 * prefix\|(.*)\|(.*)\|suffix --> prefix|$2|$1|suffix

Help needed with something
I don't get this damn bot and the code at all, but I'd like to know how to force it to find a random part of text between two common parts of code and remove it. The part of code looks like; }}
 * Other = text

Now I tried somethings but i would totally rampage the entire article. Is there a regular expression that will force it to only pick the part of random text and remove it? I want that whole line gone and replaced with just }}. --Light Daxter (talk) 21:16, 28 June 2010 (UTC)


 * Did you mean |Other = text }} or |Other = text
 * }} ? The first is easy; the only hard part is escaping the metacharacters (see the AutoWikiBrowser/Regular expression table entitled "Metacharacters (must be escaped)", to get \|Other = text \}\}. The second is harder. Use the Multiline parameter, but that doesn't always do what I expect. I'll experiment with it if that's what you wanted. Art LaPella (talk) 23:12, 28 June 2010 (UTC)

The latter is what I need, I hope you can help me out! --Light Daxter (talk) 12:25, 29 June 2010 (UTC)


 * Yes. Before I explain how, first I'll ask again if that's what you really want. Why would you want to remove the last parameter of a template, only if the }} is encoded on the next line? Perhaps you meant to remove the last parameter whether or not the }} is encoded on the last line.


 * PROBLEM 1: This changes |Other = text
 * }} to just }}, ONLY if it is encoded on two lines.


 * SOLUTION 1: In AWB, click "Options", "Find and Replace" Enabled, and "Normal Settings" to get to the Find & Replace menu. Under "Find", type (\|Other\s*=\s*text\s*\)$ or you may want instead to type it without the \ to make it (\|Other\s*=\s*text\s*)$ Under "Replace", type $1LINE ENDS HERE Among the 6 check boxes to the right, check "Regex" and "MultiLine", and leave "Enabled" checked. Go back to the "Find" column underneath where you just entered (\|Other\s*=\s*text\s*\)$ and this time enter \|Other\s*=\s*text\s*\LINE ENDS HERE.:?\}\} once again omitting the br if desired. In the Replace column underneath $1LINE ENDS HERE type }} In the six check boxes, check "Case Sensitive", "Regex", and "SingleLine", and leave "Enabled" checked. Click "Done". I encoded the brs so I could test it on this talk page.


 * P.S. A third Find & Replace line is needed in case the next line of the article isn't a }}. So find LINE ENDS HERE replace with nothing and check "Case Sensitive" (and leave "Enabled").


 * PROBLEM 2: This changes |Other = text
 * }} to just }}, WHETHER OR NOT it is encoded on two lines.


 * SOLUTION 2: Go to the Find & Replace menu as in Solution 1. Under "Find" type (\|Other\s*=\s*text\s*\\s*)\}\} (or omit the br as before). Under "Replace" type }} Check "Regex" and leave "Enabled" checked. Art LaPella (talk) 00:08, 30 June 2010 (UTC)

I added the }} because the other field is the last one, I thought it'd be easier, but maybe not. I tried both solutions, but neither work. Maybe it is of importance to note I am trying this on wikia, but I doubt it. I don't suppose the amount of spaces between |other, = or the text is of importance either. I don't suppose I can just let you use the bot account and do it that way? --Light Daxter (talk) 14:29, 30 June 2010 (UTC)


 * The number of spaces shouldn't matter because I encoded \s* between other, =, and text (and  ). \s means a space, and * means any number of repetitions including zero. I haven't ever used wikia or bot accounts, but I've seen questions like this more often at Wikipedia talk:AutoWikiBrowser. Art LaPella (talk) 20:28, 30 June 2010 (UTC)

How do I add a line break

I tried the documented \n but it doesnt seem to work it just place the text \n betwen the two parts. --79.183.192.85 (talk) 03:50, 20 May 2012 (UTC)

Help searching for dates
I'm trying to use the database scanner to search for dates, in particular, in the range from 0000-01-01 to 1599-12-31, with the date in that format. I ran the database scanner and received article names that didn't seem to have anything that matched the first pattern I tried (since I didn't save that pattern, I won't waste your time on something that might have a typo). So I tried the AWB Regex Tester, and tested the following pattern:

I then put some text to search that seemed like it should cause some hits, but the tester said there were no matches:

So what am I missing? Jc3s5h (talk) 00:09, 2 February 2014 (UTC)


 * Never mind, I see one error in the regular expression (first digit of month could also be 2 or 3), although that doesn't really explain why it didn't work. Jc3s5h (talk) 02:36, 2 February 2014 (UTC)
 * Well... You could get much more specific given your date range. I assume that you are saying it is YYYY-MM-DD (i.e. with zero padding).
 * That would limit it such that it does not find things like 1289-13-27, or 1289-01-45. Looking at it again, given that you are including the year 0000, the year construct is overly complicated. It could be:

replace years
I need to make Regular expression to link years, for example: 1966 → 1966 --Ibrahim.ID »» 19:42, 12 February 2014 (UTC)


 * Since not all numbers are intended as years, the solution depends on the range of years you want to search for. The following regex find/replace script should find and put square brackets around all numbers between 1900 and 2099:
 *  (19|20)([0-9][0-9]) &rarr; $1$2 
 * Though note that, in general, years shouldn't be linked according to the Manual of Style. SiBr4 (talk) 19:56, 16 February 2014 (UTC)
 * I suggest that you qualify that regular expression a bit. As it is, it will match any four digits (e.g. a sequence such as 2731934878374 &rarr; 2731934878374 ). While your selector could get more complicated depending on what you were actually desiring to do, the following will limit matches to those where the four digits in the 1900–2099 range are surrounded by a word boundary:
 *  \b(19|20)([0-9][0-9])\b &rarr; $1$2 
 * or (an alternate construction of the same thing):
 *  \b((19|20)(\d\d))\b &rarr; $1 
 * These both result in:
 * 2731934878374 2013-04-19 1966 2013/04/19 1966 &rarr; 2731934878374 2013-04-19 1966 2013/04/19 1966
 * , I would second the issue mentioned regarding the the Manual of Style being against the general linking of years which you say you desire. Your request for a regular expression to perform year linking implies a wholesale change to linking all years on a page, perhaps across multiple pages. Doing so is against the policy stated in WP:YEARLINK. On the other hand, it is possible that you are making changes, somewhere other than enwiki, where such linking is desirable. Makyen (talk) 21:39, 16 February 2014 (UTC)
 * I noticed that but didn't know how to fix it (I'm pretty new to regex too), so thanks for that. SiBr4 (talk) 21:46, 16 February 2014 (UTC)
 * You could further simplify it by removing one set of parentheses:
 *  \b((19|20)\d\d)\b &rarr; $1 
 * or even do this:
 * <tt> \b((19|20)\d{2})\b &rarr; $1 </tt>

changing case

 * I haven't found it. My workaround is to have my software give me messages to fix something myself.


 * Example, enforcing the "sentence case" clause at MOS:HEAD:
 * Before: ==Rules and Regulations==
 * My software changes it to: ==Rules and QRegulations==
 * That makes the software highlight the line so I notice it. If it's a false positive (proper nouns are common) then I manually remove the Q. In this case, I manually remove the Q and then change "R" to "r". Art LaPella (talk) 05:42, 25 February 2012 (UTC)

Although AWB does not support changing regex hits to upper case directly (unlike eg perl regexes it's not possible just to add eg <tt>\U</tt> in the replacement string), the same result can be achieved by using subst and MediaWiki's template syntax in the replacement:
 * <tt> </tt>

Regex for film article citations

However, I can't work out how to write a regex that will capture expressions of this form without picking up a lot of other things, or spreading its capturing across multiple s. Any suggestions from you regex aces out there?

Converting wikitables help needed
I'm trying to transform some wikitables into templates on TV episode pages using AWB. In doing so, I only want the tables in certain sections changed (e.g., sections starting with "Episode" or "Series"). I'm trying to approach it by having the script search for that section header until the start of a wikitable, and replace the stuff above the wikitable. I'm rather new to RegEx so kindly bear with any ignorance on my part. What I currently have is a shitton of subrules addressing possible parameters of Episode list which is generally working, but getting the first part to only address wikitables in episode lists (and not, say, a wikitable of a song list within the same article like on My_Little_Pony:_Friendship_Is_Magic_(season_1)).

The code I was trying is searching for  and replacing with. AWB has crashed on me twice while I've fiddled with the coding so I figured I should come here and ask.

Is there maybe a way to do if/then statements in regex? Or have it only work in certain sections of the article? Any help would be appreciated. Please ping my in any replies. Thank you.  Eve rgr een Fir  (talk) Please &#123;&#123;re&#125;&#125; 19:05, 7 April 2016 (UTC)

Match any string in the middle of the pattern, except a certain string
Hi,

I'm correcting the formatting of a grammar book of Biblical Hebrew in Wikisource. It has a lot of references to Bible verses. Most of them are formatted using a template ("GHGbible-ref"), but some are not formatted and appear as 12:34 (pattern: ).

These that aren't formatted most often refer to the same book of the Bible as the last "GHGbible-ref" template that appeared before them. Some more text may appear between the end of the template and the.

Here's example wiki syntax (from a previous version of s:Page:Gesenius' Hebrew Grammar (1910 Kautzsch-Cowley edition).djvu/343; and please try to ignore the very complicated words):
 * In conditional clauses both in the protasis and apodosis, or only in the latter,  (or had to walk)... I fear (or I would fear) no evil. Very frequently also in an apodosis, the protasis to which must be supplied from the context, e.g.  but as for me, I would seek unto God (were I in thy place); 3:13, 16, 14:14 f.

Here's the pattern that I tried to use:. It's wrong, because it begins matching at " ". I need it to begin matching at " ".

I need a way to get the second instance of  in this pattern to match everything except "\{\{GHGbible-ref". I guess I need to use something with negative look-ahead or look-behind, but I am failing to find what exactly.

Any help will be appreciated! --Amir E. Aharoni (talk) 18:45, 6 October 2018 (UTC)
 * In case you haven't found the solution yet:
 * you need to be sure that the first  stay in the template, so I suggest replacing it by  . If the template may contains other template, you can remove the   if stopping at that template end is not a problem, or use a recursive regex to have balanced braces (ask if needed).
 * a negative look-ahead should do it for the second one, replace it by . If you want to select 3:13 instead of 14:14, use a lazy quantifier  . You may also use non capturing group   (a bit less readable, but it don't mess with replacement string).

Reordering of template parameters and spaces
Does someone have code that reorders infobox fields and spaces per the template list? I have a template that I need to remove unused parameters and rename deprecated parameters to their correct one, so while doing that, I'd also like to clean the infoboxes at the same time. Would appreciate any help here. --Gonnym (talk) 09:49, 3 April 2019 (UTC)

Removing a specific empty parameter
Loading from Category:Pages using duplicate arguments in template calls trying to replace in Infobox settlement:

replace with 'nothing'

 * Thank you, even better, so the whole line is removed. Now it matches | and = and removes the whole line as wanted. But still it matches wrongly in the line that has a value, second line in this example:

| settlement_type        = |           = Aguilar de Montuenga - 009 (33705333192).jpg | image_size              = TerraCyprus (talk) 16:00, 7 October 2020 (UTC)

Searching in wiki with a suffix

Remove unsupported infobox parameter
Hi everyone! I'm trying to remove the unsupported format parameter from Infobox song when making other changes. I tried using: However this doesn't work if an earlier parameter contains a template (such as cite web), and only partially removes the parameter value if format contains a piped link or a template (such as hlist). Has anyone already figured out a way to remove an infobox parameter? Thanks! GoingBatty (talk) 20:11, 25 December 2020 (UTC)
 * If that's the only parameter you want to remove, create a Module in AWB, and in the stock/preloaded text, just replace the  line with  . You'll probably want to change the Summary to "" (i.e. blank) as well. Then just check the "enable this module" box, click the "Make module" button, and away you go.

How to skip through parameters
I have some basic skills in regex, but I don't know how to skip through parameters. does not do the job.

I am trying to add the updated template  after   to Template:Infobox national football team. For example what I am trying to do:

Before:

After:

It works in most cases when using the following codes:

Find:

Replace:

However, if there is at least one parameter between "FIFA Trigramme" and "BSWW Rank" no changes will be made. Is there any solution how to quickly skip through multiple parameters? Maybe I should work with ^ and $ and set to MultiLine? Regards.--User:Tomcat7 (talk) 19:55, 16 August 2021 (UTC)

Regex help
I would like to improve a reference in thousands of NRHP infoboxes. This requires finding the value of the refnum parameter (always 8 digits) which must be there (it's a required parameter for the infobox)

 * | refnum = 11000523

 * Well, let me clarify further. The ref may or may not be named. And the tranclusion of may have other parameters and other values for version=. So to be most general, I want to find the 8-digit refnum and then, if NRISref is present, just add |refnum=nnnnnnnn. Since parameter order doesn't matter, it could be the first parameter so the rest of the line can be ignored:
 * It looks like the above solution would handle the specific example I gave. <b style="color:#034503">MB</b> 04:09, 1 September 2021 (UTC)
 * OK - try  →   instead. This should work whether the reference is names or not.  I'm presuming you'd skip the article if it already has the refnum parameter, so it doesn't check if the parameter already exists.  Happy editing!  GoingBatty (talk) 04:42, 1 September 2021 (UTC)
 * That works. I found out that some newer numbers are 9 digits, so I added a 9-digit variation. I found some edge cases where the this parameter has a line-feed in the middle - but I just remove it and do a re-parse. Overall, it works fine.

External links section
Hello.

I sorted a bit the Wikipedia:AutoWikiBrowser/Regular expression section, but I think there are too many links: that is not helping begginers to test their regexes or learn how to use it.

I am using AWB for years now, but I just grasped that it uses .NET regexes, with the help of someone on stackuser.com.

I find a bit confusing to have links to documentation about Perl and Python (but I don't know to which extend they can be helpful).

A cleanup by someone a bit more tech savy than me would be helful to non-tech savy users.

Concerning online regex testing tools, it may be nice to have several to suits everybody's tastes, but I actually think that regex101.com is the best and most used tool at the moment, so it may be the only one to be left; with a note saying that the regex library to be used is ECMAScript (JavaScript), because the default one is PCRE, and the tokens aren't the same.

Thanks, Şÿℵדαχ₮ɘɼɾ๏ʁ 10:49, 10 September 2021 (UTC)
 * I've been advised not to use regex101 as it doesn't support .NET regexes, RegEx Storm seems to be a better option. Şÿℵדαχ₮ɘɼɾ๏ʁ 15:24, 10 September 2021 (UTC)
 * Thanks for your work in this section. Since AWB has a built-in Regex tester, maybe you could add some comments to these links to briefly explain how AWB users might find these other Regex testers more useful.  Thanks!  GoingBatty (talk) 16:47, 10 September 2021 (UTC)
 * Actually, I never used the built-in tester.
 * I like to use regex101 because of its syntax highlighting, and also because it explains the meaning of the tokens and how the regex actually works point by point.
 * Even if it doesn't support the .NET flavour, I think I'm going to continue tu use it using ECMAScript, as there are not many differences for the use I have of it.
 * Again, I don't really want to edit technical pages on subjects I don't know too much (and also my technical English is far from perfect). Şÿℵדαχ₮ɘɼɾ๏ʁ 17:40, 10 September 2021 (UTC)

How to change to lowercase, etc.
Is there more in-depth documentation somewhere that would let me discover how to change matched strings to lowercase, and things like that? Or can someone tell me what variant of regex is used in AWB and JWB, so I can search for more docs outside? Or just tell me how to do it? Dicklyon (talk) 19:14, 30 January 2022 (UTC)
 * If you want to change "Alphabet", "alphabet", and "AlphaBet" all to lowercase, just search for "alphabet" with  off, and replace with "alphabet". Primefac (talk) 20:46, 30 January 2022 (UTC)
 * What I want to do is change "(Any Words)" to "(any words)". The parens establish the context.  I've seen docs on things like \L\1 for some kinds of regex, but doesn't work for ours.  I made edits like this one with a bunch of patterns in JWB, but then there were more patterns that I had not anticipated.  What I'm asking for probably won't quite solve it either, but it will be another tool to work with.  Dicklyon (talk) 00:44, 31 January 2022 (UTC)

Query help
I'm looking to do an AWB run to change all-caps titles in CS1 references to title case. Would someone here be able to help me construct an appropriate RegEx find and replace?

"Token matching" vs "Regular matching" sections
I'm not sure I understand why these two sections are named as they are. The "token matching" section shows some examples of matching within defined wikitext elements. But to my understanding, "token" in regex refers to matched groups that are later referenced by name or number, as described in the "String matching" section of the "Regular expression definitions" table. Maybe the "Token matching" section should be called something like "Matching inside wikitext elements"? And I'm not sure what the "Regular matching" section adds. — swpb T&#8201;•&#8201;go beyond&#8201;•&#8201;bad idea 13:53, 16 September 2022 (UTC)

 * @GoingBatty, good to know for future reference. Thanks. Qwerty284651 (talk) 22:14, 31 January 2023 (UTC)
 * For what it's worth, unless the edit run is going to be >500 pages, you might as well just do it manually. Sure, it's tedious and boring, but a one-time run with a relatively few number of edits will basically be over by the time the bot request trialling is done anyway. Primefac (talk) 08:56, 1 February 2023 (UTC)
 * It was a 10-page edit run to clean up redirects after a page move. Luckily, AWB has Ctrl+S shortcut. If you spam it, it goes through every page. Holding won't do it.

Mass replacement br with plainlist
I tried replacing  in this table with plainlist to avoid the annoying pause screen reader users come across. This is what I managed to  and replace it with, but it returns "unterminated group".

 * I feel like there are easier ways to do this, but purely from a "please answer my question" standpoint, you haven't closed your opening ( after the \|\|. I'm not sure if you want it to be before the br or at the end, but that's where you're unbalanced. Also, as a thought, your regex isn't going to catch the first pair of names in the table, because it's only looking at the || separator between columns. Primefac (talk) 11:04, 13 December 2022 (UTC)
 * I've been thinking about this and a lot of wikipedia pages and the heavy majority of them, I dare say, are polluted with the misage of  for it creates a annoying pauses in screen readers per WCAG and the main goal of wiki is to make editing of pages available for everyone, including the visually impaired. Using plainlist like for the above example solves this problem. Plainlist displays as if   was used on desktop and probably Mac as well, and on mobile as if the lines were separated with a newline.  There is a slight different in spacing. I want to request an RFC to solve this problem across wiki? What are your thoughts on this? Qwerty284651 (talk) 04:37, 7 February 2023 (UTC)
 * You're going to get a fair amount of resistance if you are intending on replacing all uses of br with plainlist. If you want my honest opinion on your initial query and proposal, turning a one-line table row entry into a multi-line monstrosity by using plainlist is a terrible idea from a coding perspective, because it's going to be a nightmare to delineate the table rows from the plainlist rows.

 * Some flavours of regexp support \L in the output string – (.)→\L$1 changes A→a – but I don't think that works in AWB. One solution is to change to {{subst:lc:$1}} and let MediaWiki do the work, per Help:Magic words. Certes (talk) 12:13, 19 February 2023 (UTC)

(That page is aimed at PHP coders but should apply to other PCRE implementations.)  In that sense, recursive subgroups is a relatively new and experimental feature which is neither used nor needed in the example you link.  The example given in the PHP page matches an arbitrary depth of nested parentheses (like (this)).  (In Lua we'd use %b for that, but recursive subgroups are more flexible and can do things Lua can't.)  Of course, the term may have other meanings of which I'm unaware.

 * I don't know if this adds to or subtracts from the conversation, but the example cited by (I haven't tested it) seems to attempt to solve the problem of matching a construct like   without stopping at the first ]] in a way that uses basic industry-wide regular expression syntax. The idea would also work for   (a particular challenge of mine). As AWB uses the Microsoft RE engine, you'd be using the MS RE dialect. Somewhere in the AWB code (I forget where) it uses the Balancing Group Definitions (halfway down that page). I used to work for Microsoft and every time I try to understand that section I feel more stupid. But, again, I haven't tested the cited example which uses nested )* constructs.

 * Adding: if you have the source, WikiFunctions\Parse\UnbalancedBrackets.cs has a bunch of them, and they are fairly easy to modify without fully understanding them. David Brooks (talk) 02:26, 4 February 2023 (UTC)
 * @Certes@DavidBrooks, I moved the "recursive subgroups" part of the discussion here. Qwerty284651 (talk) 16:53, 4 February 2023 (UTC)
 * Beware that { {...}} is particularly tricky to match because templates can have triple braces around parameters. { {T1|{ {T2|{ {T3{{loop|6|} }} and { { {P1|{ { {P2{{loop|6|} }} both have six closing braces, but the first is three }} template ends and the second is two }}} parameter ends.

 * Aren't the 3 x2 parameters nested templates, whereas the 2nd example are a couple of positional parameters? Qwerty284651 (talk) 04:25, 7 February 2023 (UTC)
 * Yes, and a regexp presented with six closing braces will have to work that out. Pairing single braces usually works, but they occasionally pop up unmatched in unexpected places. Certes (talk) 12:44, 7 February 2023 (UTC)
