How to get the matched string









I am using StrMatches method to find if string contains sub string using regular expression. StrMatches returns True if string matches else False. Now I want to retrieve the matched string. For ex.

sString = "Test String:Whats going on"

sRegExpr = ".*Whats go.*"

Utility_StrMatches = aqString.StrMatches("^" & sRegExpr & "$",sString)



This will return True. How to retrieve the extact matched string. For above ex. code snippet should return "String:Whats going".





Example 2.

sString = "Test String:Whats going on"

sRegExpr = "go.*g"



Expected output: "going"





Example 3.

sString = "Test String:Whats going on"

sRegExpr = "Test .* on"



Expected output: "Test String:Whats going on"

    Hi Mustak,



    aqString.StrMatches doesn't capture matches. You need to use the language's native regular expressions for that. For example, in VBScript, you need to use the RegExp.Execute method.



     Sub Test

       Dim sString, re, colMatches

     

       sString = "Test String:Whats going on"

       Set re = New RegExp

       re.Pattern = "go.*g"

     

       Set colMatches = re.Execute(sString)

       If colMatches.Count > 0 Then

         Log.Message colMatches(0).Value

       Else

         Log.Message "Match not found"

       End If

     End Sub
