XPath checker doesnt work with xpath functions.(Solution code attached)

[GoogleCodeExporter]

Assume that the xpath expression //td[@id='testid'] returns "helloworld".
Suppose I want to use a Xpath function, say substring it doesnt work.

like,

substring(//td[@id='testid'],2,5) doesnt display "ellow"

This is because the function "getXPathNodes" is coded to always expect a set of 
nodes from the "document.evaluate" function. But the "document.evaluate" 
function may also return a string, number or a boolean data type, which is the 
case in the example above.

I modified the code and it is working fine. Attaching the file window.js with 
the changes. I modified the following two functions for this :

-- getXPathNodes
-- search

Thanks for the patch! I've uploaded a new version (with some small changes). It 
should be available for download as soon as someone at Mozilla reviews it.
