RE: [xsl] Getting a NodeList from a NodeList

[cknell@xxxxxxxxxx]

Reading your message reminded me of my earlier work with XSLT. I frequently wanted to use script functions and "loop" over nodes, but I later learned, for the most part, that it's a lot less trouble to do things like that in XSLT without using extension functions. If you can plainly state why you chose to use extension functions rather than straight XSLT, you may have one of those rare cases where this approach is justified. If you can't, you may be trying to pound in screws with a hammer.

Show us a sample of your input and a sample of your desired output and let us see if this can be solved more simply.

Subject:  [xsl] Getting a NodeList from a NodeList

Hi 

I am using XSL and MSXML 4 to do some reports. I have a main body of XSL which selects from an XML tree all employees who belong to a particular department which is a list being looped over already. The current department value is stored in $deptName

<xsl:for-each select="mycomp:getFilteredEmployeeRecords(//employee[./@department = $deptName])"> 

Here, I am passing the result of "all employees in the current department" to a MSXSL:SCRIPT function where I want to filter the node list even more and return it. 

Let's say I want a node list of all employees called John from the node list that I pass into the function to come out.

My problem is that nodeList is a DOMNodeList and does not have what I need to select another nodeList from it...i.e Node's selectNodes. All it has is the ability to get a node. 

I want to do something like

function getEmployeeRecords(nodeList) { 
return nodeList.selectNodes("/employee[@name='John']"); 
} 

The problem is that nodeList is a list of EMPLOYEE nodes. 

How can I return a nodeList from my function which is all EMPLOYEE nodes in nodeList with name = John?

I have thought about sibling functions but I am not sure.
