[Semantic Data Extractor]

Thanks for a great service!  I have been trying to evangelize good
semantics for some time, and this tool is a great demonstrater of the
need. However, I've encountered a slight problem.
 
Well-marked-up pages (XHTML-compliant, CSS-compliant, well-organized
semantically), which can be analyzed without issue at this page
(http://www.w3.org/2003/12/semantic-extractor.html) in Opera or IE6,
sometimes return an error in Firefox.  This is the error:
Using org.apache.xerces.parsers.SAXParser
Exception net.sf.saxon.trans.DynamicError:
org.xml.sax.SAXParseException: The markup in the document following the
root element must be well-formed. 
org.xml.sax.SAXParseException: The markup in the document following the
root element must be well-formed.
Thought you'd want to know.  Thanks again!
 
Best regards,
