The search would still work, but will be broken due to the possibility that some contents won't get indexed. These contents won't appear in the search results. It's something like what you said in the 3rd para in the first post about looking for </a> tag for the <a/> tag! You can't test this by searching for *few* queries. But from what I have seen, the un-indexed content for html is fairly low, and therefore you can depend on it with a small amount of error. On the other hand, XHTML is completely based on XML, so the SAX XML parser has no issue in parsing the content. There's some tools out there to parse dirty HTML tags and retrieve it's whole content. But lot of good tools don't have a compatible license with DocBook. Htmlcleaner looks like a good solution for adding the support for indexing/searching *html* files though. So, full support for html would come! Regards, --Kasun -- ~~~*******'''''''''''''*******~~~ Kasun Gajasinghe, University of Moratuwa, Sri Lanka.
