get linked css files via a regexp in a html-page

Question

i try to parse a html page which a have loaded with perl. i need to get the src="asd/jkl/xyz.css" for example out of the html-repsone to manipulate the path to an absolute.

the reason why i want to do this is, that is need the css inline in a E-Mail head ...

so my try to realize this is:

load the page via perl
get the src of the linked css
load the css files via perl
parse the css und put the contents of the css files in the head-tag of my generated email.

has anyone a better idea or a working regex?

If you want to use a regex, you have to show the exact text you will be parsing: there's a difference between <link rel="stylesheet" href="foo.css"> and <link href="foo.css" rel="stylesheet">, for example. Having said that, it is rarely a good idea to parse HTML with regex. Use a real HTML parser as tenub suggested. — ThisSuitIsBlackNot

Try something like this:

#!/usr/bin/env perl

use XML::LibXML;

my $parser = XML::LibXML->new();
my $doc = $parser->load_html(location => "http://mywebsite.com", recover => 2);

print $doc->findnodes('//link[@rel="stylesheet"]/@src');
