Need help with XML Dom

Hi,

I am trying to implement something where i read a XML into a XMLDOM object
and then look for specific elements inside the root element. I read an
attribute of that element and then within that element try to look for
another specific element and process that.

The problem i am facing is the selectNodes in the inner loop is getting all
the ClientLog elements in the doc. What I want here is to get the child
elements only for that particular node.

Set doc = Server.CreateObject("MSXML.DOMDocument")
doc.load(resultXmlFileLocation)
doc.setProperty "SelectionLanguage", "XPath"
If Len(namespaceSetting) > 0 then
doc.setProperty "SelectionNamespaces", namespaceSetting
End if
Set root = doc
'Set selectedElems = root.selectNodes("//s1:ScriptTestResult")
Dim selectedElems
Set selectedElems = root.GetElementsByTagName("ScriptTestResult")
Dim logElements
For i=0 to (selectedElems.length - 1)
Set attr1 = selectedElems.item(i).GetAttributeNode("envName")
envName = attr1.value

set logElements =
selectedElems.item(i).selectNodes("//s2:ClientLog")
<% =envName %><br /><% = logElements.length %><br />

I have this code as a part of a ASP script. Any help is truely appreciated.

Thanks,
Rajesh

Rajesh,

The "//" at the start of the XPath expression means get all child elements
from the root of the document throughout (the so-called descendant or
self axis). The fix should be just to remove the "//" which gives you,

set logElements = selectedElems.item(i).selectNodes("s2:ClientLog")

The child axis is the default, so it will get only the immediate children of
the context node.

Thanks Derek, that worked.

I was thinking that in the context of the node, the node will be treated as
a separate XML doc and so was using the "//".

On a side note the elements that I was trying to look for were not the
immediate childs so the query that I used now is "*/*/s2:Clientlog"

Thanks,
Rajesh
