Derek,
I've had a dig around in the Javadocs but I can't work out how to do
this. Could you give me a pointer on
how to access the ScriptScanner before I start parseing. I need to get
this working as not only is
HtmlParser not recognising the tag correctly, when it's part of a very
large script block, when I convert
back to Html with NodeList.toHtml() a </script> tag is being
erroneously inserted.
Regards
