xml-dev - Need a tool that converts HTML into well-formed XML, and nothing more.

[Dylan Walsh <Dylan.Walsh@Kadius.com>]

Hi. I am working on preparing examples of HTML, created by professional web
designers, for use with XSL transformations. Obviously the markup needs to
be made well-formed for this purpose. I am familiar with Tidy from the W3C,
however that utility goes beyond what we need, as it makes changes to
conform to their standards. This unfortunately results in visual anomalies
in the output.

I understand the arguements behind XHTML etc., however the markup we are
given is designed to work look good with older browsers, on different
platforms. Is there any software out there that converts HTML to be
well-formed XML, but does not make changes beyond that, e.g. to obey the
HTML or XHTML standards?
