in thread How to grab a portion of file with regex

Well instead of trolling why not supply a working example to help ?? Its always the Anonymous Monk lacking courage to put a name to a comment

How is it trolling to point out the shortcomings of a "solution"? Maybe you should look up the definition of troll

What courage is required to point out a simple fact about HTML::Parser? Are you under the impression that HTML::Parser is a high level parser?

Your "solution" doesn't fetch the portion of page from class = lastUnit to class = line margin10 -- its incomplete -- it is lots easier/shorter/simpler to use  m{\Q$start\E(.+?)\Q$end\E}i instead of that HTML::Parser low-levelness

Have you seen Re: How to grab a portion of file with regex (don't)? Its not unlike a minimum of three different tutorials/walkthroughs/step-by-step-instructions on extracting/xpathing the dom , some even compare/contrast with HTML::Parser

    You make some valid points. The example in the question didn't seem to need the content of the div.
    I do agree that working with the DOM is a much better way to parse HTML.

      #!/usr/bin/perl -- use strict; use warnings; use XML::LibXML; my $dom = XML::LibXML->new( qw/ recover 2 / )->load_html( location => q{junk.html} ); for ( $dom->findnodes(q{ //div[ contains( @class, 'lastUnit' ) ] }) ){ print "\n", $_->nodePath, "\n\n$_\n"; } __END__
