[Zope] How to check for valid HTML?

Hi, Is there a way to check (in a Python script) if a given string is valid HTML code? Ideally, it should return some useful error message (e.g. what you get from the TTW) if the code is not valid HTML. And: Does already some sort of "html_unqoute()" (reversing the effect of html_qoute()) exist in Zope? Thanks, -- Martin This eMail was sent to you using the latest weapon in the war against SPAM.
