If it was a well-formed HTML document, then yes. But as said, in reality there 
are a load of HTML documents which contain text with raw less-than characters, 
supported by the fact that all major HTML browsers can handle it. libxml's 
HTML parser is yet an exception here.

Attached you find a patch, suggesting a fix for this issue.
