I should also have pointed out that using the above ElementSoup code can 
parse the following text::

     <html><head><title>URLs</title></head>
     <body>
     <ul>
     <li<a href="http://domain1/page1">some page1</a></li>
     <li><a href="http://domain2/page2">some page2</a></li>
     </body></html>

where the HTMLParser code raises an HTMLParseError.
