With XPath 1.0 if you have a path
   element-name
(or e.g. body) then the XPath expression selects elements of that name 
(e.g element-name or body) in _no_ namespace while XHTML elements are in 
the namespace http://www.w3.org/1999/xhtml. To select elements in a 
namespace you need to bind a prefix (e.g. 'xhtml) to the namespace URI 
and use that prefix in your expression (e.g. xhtml:body). So with the 
W3C DOM Level 3 XPath API you use a namespace resolver as follows

var body = document.evaluate(
   "//xhtml:body",
   document,
   function lookupNamespaceURI (prefix) {
     switch (prefix) {
       case 'xhtml':
         return 'http://www.w3.org/1999/xhtml';
     }
   }, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue;
