[Semantic Data Extractor] - meanings of error reports?

I have looked to find an explanation of the msg. I get after 
submitting a page to the Semantic Extractor and can find no 
explanation.

Is there somewhere information about possible responses one may 
get when submitting a page. On several sites I get the following 
msg.:

Using org.apache.xerces.parsers.SAXParser
Exception net.sf.saxon.trans.DynamicError: 
org.xml.sax.SAXParseException: Content is not allowed in prolog.
org.xml.sax.SAXParseException: Content is not allowed in prolog.

And on other page I received a msg. about not having a closing 
</div> and that is not true. (All the pages I am checking have 
passed the HTML Validation for XHTML Strict.

A page of error meanings would be extremely helpful.

Thank you for your time.
