XOM API for Processing XML with Java

Thanks!

How do I add a mapping between "" and "http://www.w3.org/1999/xhtml"; 
exactly?
I tried various combinations of context.addNamespace(..,...) but nothing 
seemed to work.

Also the URL I'm using in the search below (as a sample is)

String url = 
"http://collection.fng.fi/wandora/w?museumfilter=&lang=en&artworkclassfilter=&action=gen&timefilter=&si=&query=kuopassa&qtype=http%3A%2F%2Fwww.wandora.net%2Fartwork&ifilter=all#listmod";;

There are several nested tables and as per firebugs "Copy Xpath" I tried 
the following:

"/html:html/html:body/html:table/html:tbody/html:tr/html:td/html:table/html:tbody/html:tr/html:td/html:table[2]/html:tbody/html:tr/html:td[2]/html:table/html:tbody/html:tr/html:td/html:table[4]/html:tbody/html:tr[3]/html:td[3]"

and nothing seems to come back.Hacking around it seems the deepest I can 
go is

"/html:html/html:body/html:table/html:tr/html:td/html:table"

I even tried

"/html:table[@class='content_container']" but that doesn't even work 
although there is clearly a table with class content_container in the 
HTML. I wonder if it has anything to do with the fact that a comment 
that is included i.e. some part of the HTML looks like this:

</div>
                   </td></tr></table>
               <!--- *** HEADER ENDS 
************************************************** -->
<table class="content_container"><tr><td colspan="1" rowspan="1" 
class="content_container_margin"> </td><td colspan="1" rowspan="1" 
class="content_container_column">

Not sure if that's a problem...

Thanks, Jason
