Safari XPathEvaluator

Hi…

First time poster here. I was wondering if anybody could possibly help me? I have a slight problem when trying to traverse an XML document in Safari on a Mac (This works fine in Safari on Windows by the way). On the following line:

[CODE]var xpe = new XPathEvaluator();[/CODE]

I get the following error in the Safari javascript debug console:

[CODE]Can’t find variable: XPathEvaluator()[/CODE]

Does anybody have any ideas as to what this error might be? I’ve hit a brick wall to be honest.

Thanks in advance.
Danny.
