Use a Data Stream as a Source for DOMDocument

Question:

Instead of using:

oXML.Load "c:\program files\xml notepad\Appntmts.xml"

I want to do something like:

oXML.Load Command()

where the Visual Basic Command function returns an XML formatted data stream passed on the command line. In the previous example, the Load accepts the string without complaint, but none of the document properties return anything valuable. It seems to be treating the data stream as a URL.

Answer:

If your Command object returns a String type, then all you need to do is use the .LoadXML method instead:

oXML.LoadXML Command()

LoadXML takes a well-formed XML string and converts it into a DOM object. For example, let's say that you wanted to create a stub XML structure:

function getStub(rootName as String,collectionName as String)
   dim buffer as String
   buffer="<"+rootName+">"+vbCRLF
   buffer=buffer+"<"+collectionName+"/>"
   buffer=buffer+"

By the way, you can use the .load function to load an already existing DOM into another DOM:

xmlDoc.load myDoc

This will actually create a duplicate to myDoc within xmlDoc, rather than simply passing a pointer.
