Can't load node from .jdf file in Vbscript

I'm trying to get a value from a node in a .jdf file. It gives us an error

object required: 'curNode'

in line no. 13 - inputFolder = curNode.getAttribute("Amount")

We don't really know what to do... any help please?

Thank you

'creates the msxml object
Set xmlDoc = CreateObject("Msxml2.DOMDocument.6.0")
Dim xmlDataPath,retVal
xmlDataPath = "C:\Users\liatte\Desktop\Aviv Omer Neta\JDFs to Txt\a.jdf"

'load the xml data of the script
retVal=xmlDoc.load(xmlDataPath)

'get input folder
Set curNode = xmlDoc.selectSingleNode("//JDF/ResourceLinkPool/ComponentLink")
Dim inputFolder
inputFolder = curNode.getAttribute("Amount")
Solution

  • If an XPath expression like //JDF/ResourceLinkPool/ComponentLink does not select elements in your input document then it is likely that you are processing a document which uses namespaces, see http://en.wikipedia.org/wiki/XML_namespaces.

    With XPath 1.0 a path like /foo/bar selects bar child elements of foo elements in no namespace while with an XML document of the form

    <foo xmlns="http://example.com/ns1">
  <bar>baz</bar>
</foo>

    the elements are in the namespace http://example.com/ns1.

    With your sample there is probably a default namespace declaration (e.g. xmlns="http://www.CIP4.org/JDFSchema_1_1") which requires you to change your XPath expressions by defining a prefix for the namespace e.g. 

    xmlDoc.setProperty "SelectionNamespaces", "xmlns:jdf='http://www.CIP4.org/JDFSchema_1_1'"

    and using it:

    Set curNode = xmlDoc.selectSingleNode("//jdf:JDF/jdf:ResourceLinkPool/jdf:ComponentLink")
