Yes, but the easiest way to do it is probably via XSLT.

I have recently read an announcement for
http://mercury.ccil.org/~cowan/XML/tagsoup/
I don't have any experience with that software myself but if it works as announced then you can use a SAX API to parse HTML tagsoup and then use SAX events to produce the desired output. There is also TSaxon named on that page as part of the package that allows you to transform HTML to XML so all you would need is to write an XSLT 1.0 stylesheet transforming the HTML as needed to XHTML.

I would rather say it is impossible with XSLT.
Html is, per definition not an XML language, and thus cannot possibly be transformed with xslt, which requires valid XML input. If the html would be valid XML, you would call it XHTML, not html.

Transformation of XHTML to html is off course possible (but not desirable

XSLT is a complex, slow solution. I'd be surprised if it's the easiest way. I'm not up-to-date on JAVA APIs, but with C or C++ it's much easier than that, and I'd expect NekoHTML to offer a good solution in Java.

Nonsense. XSLT starts with a DOM tree, which can equally well represent an HTML or an XHTML document. As soon as you've parsed the HTML to DOM, your XSLT parser can pretend it was XML all along (and if you apply the identity transform, you've just converted to XHTML).

But by the time you've generated the DOM, you've already done more work than you needed to. SAX is just as easy.

It seems I've always been terribly mistaking.
The word 'DOM' doesn't even occur in the XSLT 1.0 nor the XSL1.0 specification. But now I found what you're saying is indeed stated (in the XSLT2.0 working draft).

Thanks for the correction

No.

You have two problems; translating HTML (not always well-formed XML) into something manageable, then translating this intermediate format to XHTML-MP.

I suggest you download a copy of Tidy (from HTML-Kit), then read the source code and the comments. Converting HTML to XHTML reliably is a hard problem, in the awkward cases.
