Fredrik Lundh: Rene Pijlman: [end tag in html comment in script element] The end tag it chokes on is in comment, isn't it? no. STYLE and SCRIPT elements contain character data, not parsed character data, so comments are treated as characters, and the first / ends the element. Ah, I see. I'll report the problem to the application that's generating this broken code (vBulletin forum)... if you have broken documents, you can tweak this by setting the CDATA_CONTENT_ELEMENTS parser attribute before you start parsing. ... and in the mean time that's a good workaround. Thank you very much Fredrik. -- René Pijlman -- http://mail.python.org/mailman/listinfo/python-list

Hello Rene, You can also check out BeautifulSoup (http://www.crummy.com/software/BeautifulSoup/) which is less strict than the regular HTML parser. HTH, Miki http://pythonwise.blogspot.com/ -- http://mail.python.org/mailman/listinfo/python-list

Miki: You can also check out BeautifulSoup (http://www.crummy.com/software/BeautifulSoup/) which is less strict than the regular HTML parser. 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 :-) -- René Pijlman -- http://mail.python.org/mailman/listinfo/python-list

STYLE and SCRIPT elements contain character data, not parsed character data, so comments are treated as characters, and the first / ends the element. Rather than take your word for it, I checked the W3C HTML4 DTD and found this: http://www.w3.org/TR/html4/appendix/notes.html#notes-specifying-data 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 (/) delimiter followed by a name start character ([a-zA-Z]); note that this may not be the element's end tag. Authors should therefore escape / within the content. Escape mechanisms are specific to each scripting or style sheet language. ILLEGAL EXAMPLE: The following script data incorrectly contains a / sequence (as part of /EM) before the SCRIPT end tag: SCRIPT type=text/javascript document.write (EMThis won't work/EM) /SCRIPT In JavaScript, this code can be expressed legally by hiding the ETAGO delimiter before an SGML name start character: SCRIPT type=text/javascript document.write (EMThis will work\/EM) /SCRIPT Guess you learn something new every day. Too bad there's so much illegal code in the wild. :( -- Edward Elliott UC Berkeley School of Law (Boalt Hall) complangpython at eddeye dot net -- http://mail.python.org/mailman/listinfo/python-list
