Finding occurences

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

How can I search a site for any occurence before and after a variable? I'm trying to find every line that contains ~:~ where ~ would be any text or characters before a colon and then anything it finds after it.

`@lines = grep(/(.+)\:(.+)/, @lines); # for the whole line from an arra +y #for the parts out of lines from a file. while(<$fh>){ if(/(.+)\:(.+)/){ $before = $1; $after = $2; } }` [download] How are you applying this? There may be a module to help you. Also, this is sort of an RTFM... see grep, perlre, and perlretut. Update: I just noticed that you want to search a site. What site? You'll have to use LWP to get the pages you want to search, then use HTML::TokeParser to pull out relevant text and process it. John J Reiser newrisedesigns.com	[reply] [d/l]
