Re: Switching out characters inside links

This is totally overkill for what you want but it's a nice approach for converting HTML to XHTML and that's the subtext of your original question.

use strict;
use warnings;
use XML::LibXML;

my $raw = do { local $/; <DATA> };

my $parser = XML::LibXML->new;
$parser->recover_silently(1);

my $doc = $parser
    ->parse_html_string("<div>$raw</div>");

my $wrapper = [ $doc->findnodes("//body/div") ]->[0];

print $_->serialize(1)
    for $wrapper->childNodes;

exit 0;

__DATA__
All content is in a variable like this...<br>
<br>
<a href="http://www.somedomain.com/index.cgi?page=home&var=1&no=2&so=f
+orth&so=on">

You end up with-

All content is in a variable like this...<br/><br/><a href="http://www.somedomain.com/index.cgi?page=home&var=1&no=2&so=forth&so=on">

What does this have to do with XML? He specifically mentioned HTML where ampersand needs to be escaped as well. Especially when you consider that the semi-colon is optional in HTML. `http://www.somedomain.com/index.cgi?page=home&quot=1` [download] is the same as `http://www.somedomain.com/index.cgi?page=home"=1` [download]	[reply] [d/l] [select]

The OP asked how to get &s to &s in an existing snippet of HTML. My solution does that and it does it without saying start over and do it from scratch which often isn't an option. It also sounded like it might be an XY question and the real issue was a need to do HTML->XHTML since the vanilla HTML world isn't usually concerned whether docs validate or not.	[reply]
