Summary: htmllib quote parse error within a <script>

Initial Comment:
I am using the htmllib to parse web pages for plain text content.  I 
came across a web page that contained a script construct similar 
to the example below.  Note that the script is itself writing a script.  
The htmllib appears to be confused by the use of single and double 
quotes used within the real <script> and </script> tags.

I am using "Python 2.3 (#1, Sep 13 2003, 00:49:11) [GCC 
3.3 20030304 (Apple Computer, Inc. build 1495)] on darwin" on a 
PowerBook G4 running OSX 10.3.8.

<html>
  <body>
    <h1> This is a test </h1>
    <br>
    <blockquote>
      <script language="JavaScript">
        rnum = Math.round( Math.random() * 100000 );
        document.write( '<scr' + 'ipt src="http://www.a.org/' + 
rnum + '/"></scr' + 'ipt>' );
      </script>
    </blockquote>

Here is the Python trace:
