Tip: Convert from HTML to XML with HTML Tidy

Tip: Convert from HTML to XML with HTML Tidy: "One the challenges that webmasters face when converting from pure HTML to XML/XSL is the preservation of their legacy Web sites. Because it would be too costly to dump the old site and start again from scratch, some sort of automated procedure that brings the HTML site to XML is required.
Even XML converts have to deal with HTML files: Many products have added an option for exporting HTML documents -- an option you might want to integrate into your Web site.
This tip discusses HTML Tidy, a powerful tool to help convert old HTML pages to newer standards, such as XML. Tidy is distributed as open source."
