Need Help??

andrew has asked for the wisdom of the Perl Monks concerning the following question:

I need to poll some information after I search and replace, say my line contains "abcdbab (djdjdj) aa", how can I "just" get the infomation in the middle of ()'s. SO basically $wah would contain "djdjdj".

This is another answer: `my $wah = m/$([^$]+)\)/;` [download] See Common Regex Gotchas for information on why this is so. Regards. Edit: Apologies to dpuu for misreading the above node and thanks for pointing this out. Both forms have their pros and cons as discussed in Ovid, Long Live .*? (dot star question-mark).	[reply] [d/l]

For which reason, specifically? AFAIK, the only difference is that `/X(.?)Y/` doesn't match newlines, whilst `/X([^Y])Y/` does. --Dave	[reply] [d/l] [select]

`$line =~ /$(.*?)$/ and $wah = $1` [download] --Dave Update: oops: I forgot the capturing parentheses	[reply] [d/l]
