I attempted to put that directly in and got the same results of "null"
for body. I do not see any prefix of "xhtml" in the code so I thought
the value of prefix in the case statement may not be correct. For a test I 
changed
it to ignore the argument and just return the string 
'http://www.w3.org/1999/xhtml'.
I got the same results. I then added an alert to display the string.

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