leuce 2 Posted October 18 Hello everyone I don't know much about regular expressions. I have a string $clippie which is text that uses @CRLF for line breaks. I would like to delete everything from the second @CRLF to the third @CRLF (in other words, I want to delete the third line from the text). Can I use just one line of StringRegExpReplace for that, and if so, how would that work? Right now I accomplish this as follows (don't laugh): $clippie = ClipGet () $clippie = StringReplace ($clippie, @CRLF, @CRLF & "<<<<<", 2) $clippie = StringReplace ($clippie, @CRLF, ">>>>>" & @CRLF, 3) $clippie = StringReplace ($clippie, "<<<<<", "", 1) $clippie = StringReplace ($clippie, ">>>>>", "", 2) $clippie = StringRegExpReplace ($clippie, "<<<<<.+>>>>>", "") Thanks Samuel Share this post Link to post Share on other sites

jchd 1,271 Posted October 18 Exactly, it even offers a way to debug a pattern and look it work step by step along the subject. Keep the engine setting to PCRE as it matches what AutoIt uses.
