Booze aside, are you using Mojo::DOM for this? Below is a very short example (it's way too early on a Sunday, and I'm very low on sleep) based upon this:

#!/usr/bin/perl

use strict;
use warnings;
use Mojo::DOM;

my $html = <<"END_HTML";
<html>
<head>
<title>test</title>
</head>
<body>
<ul>
<li><a href="http://perlmonks.org" class="first">perlmonks</a></li>
<li><a href="http://archive.org" class="second">archnive.org</a></li>
<li><a href="http://sitedoesnotexist9999.net" class="third">fakesite</
+a></li>
</ul>
</body>
</html>
END_HTML

# Create DOM
my $dom = Mojo::DOM->new( $html );

# Find the first 'a' tag with 'second' class, remove the parent tag 
$dom->find('a.second')->first->parent->remove;

print $dom->content;

Output:

<html>
<head>
<title>test</title>
</head>
<body>
<ul>
<li><a class="first" href="http://perlmonks.org">perlmonks</a></li>

<li><a class="third" href="http://sitedoesnotexist9999.net">fakesite</
+a></li>
</ul>
</body>
</html>

So the output removes the <li> containing the URL selected. If you want to keep it remove ->parent from the code above and only the URL will be removed:

<html>
<head>
<title>test</title>
</head>
<body>
<ul>
<li><a class="first" href="http://perlmonks.org">perlmonks</a></li>
<li></li>
<li><a class="third" href="http://sitedoesnotexist9999.net">fakesite</
+a></li>
</ul>
</body>
</html>

Replace 'first' for whatever (the Mojo::DOM docs are super helpful) if you want to parse a whole page for your selector. Either use eval or Try::Tiny to warn/log/ignore failure to match.

Personally I find Mojo::DOM easy to read and deal with all sorts of crazy HTML/XML issues.
