Dear RegEX gurus, my brain hurts..

[steve8tch]

I have the following data

asfaf

ZCZ

wtr

aphup

lkjk

a..etc

I would like to pick up the sections

asfaf

ZCZ

wtr

aphup

lkjk

etc

Obviously the real data is more complicated and varied....

Somehow I need to match the "a". The "a" needs to be included as the first entry in each section captured and the data I require includes everything up to the beginning of the next "a"

There is a workaround , where I can do a StringRegExpReplace($str,"a","@@a") and then match between the "a" and the "@@", but my feeling is that this can be achieved with the correct pattern.

Has Anyone any thoughts ?

Thanks.

Steve

Local $sText = "asfaf" & @CRLF & "ZCZ" & @CRLF & "wtr" & @CRLF & "aphup" & @CRLF & "lkjk" & @CRLF & "a..etc"
Local $aMatch = StringRegExp($sText, "(?s)(?m)^a.*?(?=^a|\z)", 3)

If IsArray($aMatch) Then
    For $i = 0 To UBound($aMatch)-1
        ConsoleWrite($i & ":" & @CRLF & $aMatch[$i] & @CRLF)
    Next
EndIf

Well done, and thanks. I have adapted for my example and it works well.

This has been a great learning for me.

I never new about the ?= "look ahead" option. I can't see it documented in our help file (although now I have looked further it is on the online PCRE section )

Thanks again.

Steve
