in reply to Is there a Limit on Matching .*

I am actually a bit shocked that no-one mentioned using a negated character class to grab what you need. The idea is to grab everything that is not the character '<':
my ($title) = $chunk =~ /<title>([^<]+)/; my @h1 = $chunk =~ /<h1>([^<]+)/g;
However, this is still not perfect. I personally think that nothing is too simple for a parser module, especially if that parser module is HTML::TokeParser::Simple:
use strict; use warnings; use Data::Dumper; use HTML::TokeParser::Simple; my $d = do {local $/;<DATA>}; my $p = HTML::TokeParser::Simple->new(\$d); my %hash; while ( my $token = $p->get_token ) { $hash{title} = $p->get_token->return_text if $token->is_start_tag('title'); push @{$hash{h1}}, $p->get_token->return_text if $token->is_start_tag('h1'); } print Dumper \%hash; __DATA__ <html> <head> <title>foo</title> </head> <body> <h1>one</h1> <h1>two</h1> <h1>three</h1> </body> </html>
