Several DataWeave functions accept regular expressions as arguments, which you can use to return or check for matches. You can also construct regular expressions that incorporate DataWeave expressions that include functions and variables.Before you begin, note that 2.x versions of DataWeave are used by Mule 4 apps. ForDataWeave in Mule 3 apps, refer toDataWeave version 1.2 examples.For other DataWeave versions, you can use the version selector in the DataWeave table of contents.Return Matches from a StringThis example uses regular expressions in a number of DataWeave functions to return matches to an input variable "mycompany.com".contains returns true based on a regular expression that matches part of the input string.find returns an array of indices that specify the matching locations in the input string. This function treats the input string as a string array.match returns an array of substrings that match the regular expression.matches returns true because the regular expression matches the input string exactly.replace returns a URL that changes .com in the input string to .net, based on the regular expression \..*m.scan returns a subarray of comma-separated substrings that the regular expression matches.splitBy splits an input string into an array of substrings based on the . in the input.DataWeave Script:%dw 2.0var myString = "mycompany.com"output application/json---{ "contains" : myString contains(/c.m/), "find" : myString find(/[m|n].|m$/), "match" : myString match(/([a-z]*).[a-z]*/), "matches" : myString matches(/([a-z]*).[a-z]*/), "replaceWith" : myString replace /\..*m/ with ".net", "scan" : myString scan(/([a-z]*).(com)/), "splitBy" : myString splitBy(/[.\/]/)}Output JSON:{ "contains": true, "find": [ [ 0 ], [ 4 ], [ 7 ], [ 12 ] ], "match": [ "mycompany.com", "mycompany" ], "matches": true, "replaceWith": "mycompany.net", "scan": [ [ "mycompany.com", "mycompany", "com" ] ], "splitBy": [ "mycompany", "com" ]}For function documentation, see:containsfindmatchmatchesreplacescansplitbyUse DataWeave Variables and Functions in a Regular ExpressionThis example constructs a regular expression by using the DataWeave concatenate function (++) to incorporate a DataWeave variable into a regular expression.The regular expression matches "somebiz". The example uses replace and with to replace "somebiz" with "abcd".DataWeave Script:%dw 2.0var myCompany = { "name" : "biz" }var myInputA = "somebiz-98765"output application/json---{ example: myInputA replace (("(^s.*e)" ++ myCompany.name) as Regex) with ("abcd")}Output JSON:{ "example": "abcd-98765"}See Also

It uses a symbolic representation based on intervals of Unicode characters. RegexPal JavaScript Tester JavaScript Regular Expression Tester RegexPal is a simple but fast and powerful web-based JavaScript regular expression tester. It includes real-time match highlighting, and regex syntax highlighting. Sql RegEx Use SQL2005 and Regular Expressions With the advent of Sql Server 2005, Microsoft's DB can now use external DLLs like other .NET languages. This article provides a library of the basic regex functions and describes how to bootstrap it into SqlServer. SketchPath SketchPath SketchPath is a .NET XML/XPath/Regex development tool.It provides a rich graphical environment for 'as you type' matching of XPath or Regular Expressions against a loaded text/xml source file.If matching regular expressions against an XML file, the XPath locations of matches are auto-generated as you scan through the results.A free Beta version is available now. Online regex tester Regular Expression Editor Java-applet that helps you test regular expressions flavor of the Sun Java standard API (java.util.regex) Full highlighting of regular expression syntax for an easy visual clue (including bracket matching, error detecting) Tooltips will be shown when the mouse is over a part of the regex. Evaluates your regular expression while you are typing; 4 distinct match modes: Find a sequence of characters; Match a complete

I think the easiest way to accomplish this is a regular expression replace.Press CTRL+H to bring up the Replace window.In the "Find What:" box, type a regular expression to match the double email addresses. I used the expression .*@.*@.*Leave the "Replace with" box empty to clear out these lines.In the "Search Mode" box, select the "Regular expression" button. Make sure ". matches newline" is unchecked.Note, there are much better email address regular expressions. The one I provided simply looks for two @ symbols on the same line with 0 or more characters before, between, and after those @ symbols.UPDATE:In response to the comment of matching 2 email addresses next to each other, this is much more difficult to do as there's no straightforward way to determine where the first email ends and the 2nd begins. For the exact case given in the comment, you can use the "Find what" (.*?\@.*?\.com)(.*@.*:.*) with a "Replace with" box value of \2. (Again, there are much better expressions you can use, but this is quick and dirty).This regex find an email address ending in .com in the first RegEx match, and another email address, colon, and additional text is the 2nd match. The "Replace with" will leave the 2nd match (the one you are looking for).

The desired information.To avoid that, you can use regular expressions to be more specific about what you're looking for. For example, to find only lines that start with the word Port, you can use the regular expression operator ^, like this:$ grep ^Port /etc/ssh/sshd_configPort 22This time grep returned only the line that started with Port since, in the second line, the expression Port is in the middle.You can also use extended regular expressions with the command-line parameter -E. For example, to search for a pattern that contains the word Port followed by numbers, use this regular expression:$ grep -E "Port [1-9]+" /etc/ssh/sshd_configPort 22You can also look for lines that end with a text pattern by using the $ operator. For example, to find all lines that end with none in sshd_config, use grep like this:$ grep none$ /etc/ssh/sshd_config#RekeyLimit default none#AuthorizedPrincipalsFile none#AuthorizedKeysCommand none#ChrootDirectory none#VersionAddendum none#Banner noneRegular expressions are a big part of grep, making it powerful and flexible. However, regular expressions are a huge topic. For additional information, look at Regular expression on Wikipedia or Regular expressions 101.Find text in multiple files and directoriesSimilar to finding text patterns in a single file, you can use grep to find text in multiple files or directories. To find text in multiple files simultaneously, specify which files to search from after the first file name, or use a shell wildcard such as * for all files. For example, to search for a configuration in two files:$ grep Port /etc/ssh/sshd_config /etc/ssh/ssh_config/etc/ssh/sshd_config:Port 22/etc/ssh/sshd_config:#GatewayPorts no/etc/ssh/ssh_config:# Port 22When you use multiple files, grep shows the name of the file where it found a match before showing the matched line.[ Keep your most commonly used commands handy with the Linux commands cheat sheet. ]To run the search recursively in multiple subdirectories, use the command line flag -R:$ grep -R

What Is grep?Grep is a command-line tool that allows you to find a string in a file or stream. It can be used with a regular expression to be more flexible at finding strings. This page gives an introduction to grep. For more information enter: man grepin a terminal. How To Use grepIn the simplest case grep can be invoked as follows: grep 'STRING' filenameThe above command searches the file for STRING and lists the lines that contain a match. This is OK but it does not show the true power of grep. The above command only looks at one file. A cool example of using grep with multiple files would be to find all lines in all files in a given directory that contain the name of a person. This can be easily accomplished as follows: grep 'Nicolas Kassis' *The above command searches all files in the current directory for the name and lists all lines that contain a match. Notice the use of quotes in the above command. Quotes are not usually essential, but in this example they are essential because the name contains a space. Double quotes could also have been used in this example. Regular Expressionsgrep can search for complicated patterns to find what you need. Here is a list of some of the special characters used to create a regular expression: ^ Denotes the beginning of a line $ Denotes the end of a line . Matches any single character * The preceding item in the regular expression will be matched zero or more times [] A bracket expression is a list of characters enclosed by [ and ]. It matches any single character in that list; if the first character of the list is the caret ^ then it matches any character not in the list \ Denotes the beginning of a word \> Denotes the end of a word Here is an example of a regular expression search: grep "" fileThis regular expression matches any "word" that begins with a letter (upper or lower case). For example, "words" that begin with a digit would not match. The grep command lists the lines that contain a match.
