if more people learned something new every day, the wild would look a 
lot different.

Element content 

When script or style data is the content of an element (SCRIPT and STYLE),
the data begins immediately after the element start tag and ends at the
first ETAGO ("") before the SCRIPT end tag:


  document.write ("This won't work")


In JavaScript, this code can be expressed legally by hiding the ETAGO
delimiter before an SGML name start character:


  document.write ("This will work<\/EM>")



Guess you learn something new every day.  Too bad there's so much illegal
code in the wild. :(

Yes, thanks. Ik this case it was my sitechecker which checks for syntax
and broken links, so it was supposed to find the syntax error.
BeautifulSoup is not very well suited for validators :-)

Hello Rene,

You can also check out BeautifulSoup
(http://www.crummy.com/software/BeautifulSoup/) which is less strict
than the regular HTML parser.

HTH,

... and in the mean time that's a good workaround.

Thank you very much Fredrik.

no.  STYLE and SCRIPT elements contain character data, not parsed 
character data, so comments are treated as characters, and the first
