A lot of people have been trying to munge html with regexes
lately. HTML::Filter gives you a lot more power. I like
using something like this, sweeten to taste:
package MyFilter;
use HTML::Filter;
use vars qw( @ISA );
@ISA = qw( HTML::Filter );
sub start {
my ($self, $tag, $attrs, $attrseq, $origtext) = @_;
my $rewrite;
if (exists $attrs->{src}) {
$attrs->{src} = "http://foo.bar.com/$attrs->{src}";
$rewrite = 1;
}
if (exists $attrs->{href}) {
$attrs->{href} = "http://foo.bar.com/$attrs->{href}";
$rewrite = 1;
}
if ($rewrite) {
print "<$tag";
foreach my $attr (@$attrseq) {
print qq[ $attr="$attrs->{$attr}"];
}
print ">";
}
else { print $origtext }
}
package main;
my $filter = MyFilter->new();
$filter->parse($html);
$filter->eof();
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
Read Where should I post X? if you're not absolutely sure you're posting in the right place.
