AFAIK doesn't MSXML support this. Only a Node (selectSingleNode) or a
NodeList (selectNodes) can be retrieved using XPath in MSXML.

However, most other XPath engines do provide methods to retrieve a
number using XPath.

Yep, but what is the problem of checking the .length property on a
NodeList?

Subject: [xml-dev] XPath, count function

Hi!

I wonder if its possible to use the count function of XPath in
JavaScript. 
I'm using MSXML.

I want to count the number of elements with the attribute fnamn="Tomas"
and 
return the number:

count(//*[@fnamn="Tomas"]))

Is it possible to use that expression in a function in JavaScript and 
return the number or do I have to use the selectNodes() and check the 
number of nodes in the nodeList?

/Tomas
