Ok, I gave up on HTML: HTML is a load of rubbish, and
parsing all the rubbish that's out there would be enough to
drive the Dalai-Lama to eat a raw cow (ok I may be
exaggerating a little).

Using Jordi's help from months ago, I got an Xhtml module
that uses Xml.pm working in less than a couple of hours, and
it seems to be working quite well.

I'll submit another patch soon to update the tests.

=head1 NAME

Locale::Po4a::Xhtml - Convert Xhtml documents from/to PO files

=head1 DESCRIPTION

The goal of the po4a (po for anything) project is to ease translations (and
more interestingly, the maintenance of translations) using gettext tools on
areas where they were not originally expected like documentation.

Locale::Po4a::Xhtml is a module to help the translation of Xhtml documents into
other [human] languages.

Please note that this module is still experimental. It is not distributed in
the official po4a releases since we don't feel it to be mature enough. If you
insist on trying, check the CVS out.

=head1 STATUS OF THIS MODULE

This module is fully functional, as it relies in the L<Locale::Po4a::Xml>
module. This only defines the translatable tags and attributes.

It is derived from Jordi's DocBook module.

"It works for me", which means I use it successfully on my personal Web site.
However, YMMV: please let me know if something doesn't work for you. In
particular, tables are getting no testing whatsoever, as we don't use them.
