Need Help??

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

Hi, I want to grep a piece of code from a html source file somewhere in the middle of it. The wanted snippet is situated between comment tags. Can anyone help me getting started? (I ordered the book "regular expressions" from O'reilly. Till it arrives, I hope you guys can help.) thnx in advance, Corry.

This regular expression will grap the entire tag, brackets and all. `$data =~ m/(<[^>]+>)/; print $1, "\n"; # print the tag` [download] This regex will leave out the brackets and print only the string inside them: `$data =~ m/<([^>]+)>/; print $1, "\n"; # print the tag` [download] Use modifiers, or loops as you need too. -kel	[reply] [d/l] [select]

Comments make HTML extraction even more difficult than it usually is. However, if you're dealing with fairly standard HTML you could use `$page =~ /<!--\w+(.)\w-->;/; $commented = $1;` [download] This will grab the string inside the comment; add appropriate qualifiers to the regexp as necessary (or use another on $commented) if you only want to pick certain stuff out.
