Hello,

I want to write a function that initially will print out values of my xml file. I only want to print a certain part of the document so I use a selectNodes() call with some xpath syntax that maybe incorrect. Here is my xml document structure

<profile>
 <discovery>
 </discovery>
<changes>
   <Network_Drives>
     <network_drive id_number="0" drive_letter="X:" old_mapping="\\server1\files2" new_mapping="\\server2\files2" />
     <network_drive id_number="1" drive_letter="Y:" old_mapping="\\server2\file\test" new_mapping="\\server1\file\test"/>
    </Network_Drives>
 </changes>
</profile>

so I am trying to print out the lines inbetween <Network_Drives> to get something like this:
 
 drive_id  0
 drive_letter x:
  etc....
The output could be on a single line or spread over multiple lines I just want to access each <network_drive>'s data and be able to store it into a variable eventually. First step would be printing out the data so I know its there.

I do not really even need the descriptions (drive_id, letter) all I want to do is spit out the data (o,x: etc..)

So I have this vbscript going right now

path = "C:\myfile.xml"
Set objXMLDoc = CreateObject("Microsoft.XMLDOM")
objXMLDoc.async = False
objXMLDoc.load(path)
'Set xmlDoc = CreateObject("Msxml2.DOMDocument.4.0")
'xmlDoc.loadXML(path)
WScript.Echo "xml document loaded"

Set NodeList = objXMLDoc.documentElement.selectNodes("//Changes/Network_Drives")
WScript.Echo "Length " & NodeList.length
For Each Node in NodeList
 WScript.Echo Node.Text
Next

My output right now is:

xml document loaded
Length 1

And nothing prints from my loop.....(which I dont understand)

Can anyone help me out with my vbscript code to accomplish my desired output?

Thanks,
Barry

You need to get the attributes values from the network_drive elements.  I changed the XPATH a bit (added 'network_drive') and added the code to get the attributes values.

    path = "C:\myfile.xml"
    Set objXMLDoc = CreateObject("Microsoft.XMLDOM")
    objXMLDoc.async = False
    objXMLDoc.load(path)
    WScript.Echo "xml document loaded"

    Set NodeList = objXMLDoc.documentElement.selectNodes("//changes/Network_Drives/network_drive")
    WScript.Echo "Length " & NodeList.length
    For Each Node in NodeList
      WScript.Echo "ID: " & Node.attributes.getNamedItem("id_number").value & " Drive: " & Node.attributes.getNamedItem("drive_letter").value
    Next


You could also use indexes rather than names:

      WScript.Echo "ID: " & Node.attributes.item(0).value & " Drive: " & Node.attributes.item(1).value

Nothing printed in your original code because you were trying to print the text of the 'Network_Drives' node and there is no text.  'Network_Drives' contains only other elements which also do not have text.

Also, I had to change capitalization of "changes" in the XPATH.  I don't know if this was due to a typo.  I suspect so because your code would have done nothing if it was incorrect.  You may need to change it back to a capital to work on your XML file.  The sample XML you gace here had a lower case c.
