在VB6中检查XML声明

Question

Firstly apologies...I haven't used VB6 (or any strain of VB for that matter) for a very long time.

I had the following code

nodRoot.appendChild TempTableData.childNodes(0)

That gives the error "This operation can not be performed with a Node of type XMLDECL."

So I loop through the Child nodes as follows to not append the node if it is the XML declaration.

      Dim nod As IXMLDOMNode
      For Each nod In TempTableData.childNodes()
        If Not nod.baseName = "xml" Then
          nodRoot.appendChild nod
        End If
      Next nod

Which works ok but seems an inelegant way of checking for an XML Node declaration. So what I'd like to achieve is to check against node type = XMLDECL but I can't find a way of doing this.

Cheers.

Like you I'm dredging the depths of ancient memory, but I have a vague recollection that in the COM XML implementations, the XML Declaration node had nodeType = NODE_PROCESSING_INSTRUCTION (= 7) .

So if removing all processing instructions is OK you could filter on that, otherwise you'll still have to check the baseName, so you don't gain anything.
