The problem I have is that the asp code will work on the first loop  but throws up an error when it tries to move to next node. The problem seems to be set oNode = oNode.nextNode. is this the right function of should another be used when looping through parent nodes of XPATH Query.

 
I should be able to get:
1516---first loop
1517--second loop

XML FIle:

<MASTERSMSLIST>
      <MSISDN VALUE="1515">
            <LIST NAME="gang" COM="dfba" ORG="dfgaa"/>
            <LIST NAME="centre" COM="dfba" ORG="dfgaa"/>
      </MSISDN>
      <MSISDN VALUE="1516">
            <LIST NAME="centre" COM="dfba"/>
            <LIST NAME="exec" COM="dfba"/>
      </MSISDN>
      <MSISDN VALUE="1517">
            <LIST NAME="exec" COM="dfba"/>
      </MSISDN>
</MASTERSMSLIST>

ASP
'Unnecessary code removed

      sXPATH =      "//MSISDN[@VALUE]/LIST[@NAME='exec'][@COM='dfba']/.."
                 
                Set oNode = oListXML.SelectNodes(sXPATH)

            If oNode.length > 0 then
                      For i = 1 To oNode.length
                             set oNode = oNode.nextNode
                        'Problem seems to be with this

                               sData = oNode.getAttribute("VALUE")
                               'Do Stuff with No
                  next
            end if

oNode starts out as a nodelist object.  If you then set oNode to a single node, the nextNode() method will throw an exception as this doesn't exist in the IXMLDOMNode interface.

I prefer a notation that keeps you from making mistakes like this, where nodelists are represented by something like

              Set oNodeList = oListXML.SelectNodes(sXPATH)

Here's a loop on a nodelist in Javascript:

for (var i=0; i<oNodeList.length; i++) {
  oNode = oNodeList.nextNode();
  alert(oNode .text);
}

In VBScript, it might be something like:

For i = 1 to oNodeList.length
  set oNode = oNodeList.nextNode
Next

Ah yes, the truly enormous errors are usually obvious!  ;^)
