XOM API for Processing XML with Java

[Christophe Marchand <christophe.marchand AT axyus.com>]

As you define "html" as the prefix, your request should be

/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]

You can also add a mapping beween the default prefix "" and 
"http://www.w3.org/1999/xhtml"; to your XPathContext
