Correct me if I'm wrong, but couldn't you achieve the same result for 
the document.evaluate by

var xpath='//a[contains(text(), "Adventure again")]';
var theLink=document.evaluate(xpath, document, null, 
XPathResult.SINGLE_UNORDERED_NODE_TYPE, null);
var linkElement=theLink.singleNodeValue;

however, I can't help with the problem, sorry - I didn't think "alert" 
worked at all in GM!
