Using exslt extensions will be used in javascript xpaths

I would like to use javascript XPaths in a web application using exslt extensions, but I cannot figure out how to do this.

Pretend that I have an html document with some div files. I want to run this:

namespaces={'regexp':'http://exslt.org/regular-expressions'};
result = document.evaluate( 
             "//div[regexp:test(.,'$')]", 
             document, 
             function(ns){ 
                 return namespaces.hasOwnProperty(ns) ? namespaces[ns] : null;
             }, 
             XPathResult.ANY_TYPE, 
             null);

Only this leads to an invalid XPath expression exception during evaluation. I use chrome.

Is there anything else that needs to be done to get this stuff to work? I see on exslt.org that there are implementations for javascript, but how can I make sure they are available? Do i need to embed javascript in an element named script in dom or something crazy?

UPDATE

dom + javascript xpath, XSLT exslt- document.evaluate( , xpath)?
