HTML parser

["Alexey N. Shananin" <shananin@park.ru>]

Hi! 
I'm looking for a parser for HTML. 
I know that XML parsers can't correctly handle HTML tags because of theese 
tags might be unclosed( I mean <br> tag, but not <br/> or for example...).
I heared about XHTML standart. It's supported by XML parsers, as far as I 
know(Xerses, for example). 
Are there any transformation API's to convert HTML->XHTML or is where any 
_FREE_ HTML parser?

Thanks!
