GetElementsByTagName: object required

[Ragnar Heil]

with a special method of my application I generate this XML-tree:

<tcm:RenderInstruction xmlns:tcm="http://myNamespace">
<tcm:Item xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="tcm:16-12817-64"
xlink:title="20050309_Enterprise_Information_Integration - 16-12814
Page" xlink:type="simple"/>
<tcm:ActivateBlueprinting>false</tcm:ActivateBlueprinting>
<tcm:ActivateWorkflow>false</tcm:ActivateWorkflow>
<tcm:RenderMode>Publish</tcm:RenderMode>
<tcmublicationTarget xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="0-2-65537" xlink:title="Staging on local system"
xlink:type="simple"/>
</tcm:RenderInstruction>

Now I want to get this value: "tcm:16-12817-64" (node: tcm:Item)

I tried many different approaches like
set itemNode = objXML.selectSingleNode("/tcm:RenderInstruction/tcm:Item/@xlink:href")
---
Set itemNode = objXML.selectSingleNode("*[local-name() = 'tcm:Item]")
---
set itemNode = objXML.GetElementsByTagName("tcm:Item")

I always get the "object required"-error


thanks in advance
Ragnar

Are you using MSXML? Make sure you have at least MSXML version 3 then
you can do
objXML.setProperty "SelectionLanguage", "XPath"
objXML.setProperty "SelectionNamespaces",
"xmlns:tcm='http://myNamespace' xmlns:xlink='http://www.w3.org/1999/xlink"
then using those prefixes in XPath expression works e.g.
Set itemNode =
objXML.selectSingleNode("/tcm:RenderInstruction/tcm:Item/@xlink:href")

Watch out for line wraps the posting introduces but which are not
allowed in VBScript.

Thank you for your input, gonna try it tomorrow

setting the properties does not work this way because I dont have an
object (as I thought)

The XML-output is a string and I want to read out the value of this node
("/tcm:RenderInstruction/tcm:Item/@xlink:href")

If you are using MSXML 4 why don't you have an XML document object?
If you have a string with XML markup then you can nevertheless create an
XML DOM document object, when you have that you need to call loadXML to
parse the string.

as soon as you do it the right way, it works

thank you, Martin!
