Re: output html as lower case?

Just a little update.  I asked on the Jaxen-interest list about treating 
the HTML DOM in a case-insensitive manner.  The one response I got made it 
sound like it isn't supported currently, but there is at least one (ugly) 
workaround.

Given the following XPath expression which would be valid for XHTML....

"/html/head/title"

would have to be modified to the following for HTML

"/HTML/HEAD/TITLE"

That is, unless one uses a nifty trick (some might call it a hack)

"/*[name()='html' or name()='HTML']/*[name()='head' or 
name()='HEAD']/*[name()='title' or name()='TITLE']"


I actually tested that with Jaxen and it works.  However, JXPath returns 
nothing.  Jaxen is much better about following the spec as far as I can 
tell and if we are moving to DOM4J in XMLC-3.0, we will get Jaxen support 
out-of-the-box, since that is what DOM4J's XPath implementation is based upon.

Anyway, I'll keep on the Jaxen guys to support the HTML DOM in a 
case-insensitive way.
