XML

[Ken Ray]

Doug, the ID is actually assigned to the XML *container* (data read from a
file, or from a block of XML in a variable, etc. There has to be some
"handle" to get a hold of the XML data, assuming and environment that can
hold multiple "documents" (XML containers) in memory at the same time

Since you're using 1.5, you might want to take a look at a scripted XML
alternative for Rev and MC at
http://www.sonsothunder.com/products/metacard/xmllib.htm. Once a document is
read, each node is given a unique ID number, and you can just refer to the
node by number. So here's an example of getting the name (tag) of all the
child nodes from the root node of a bunch of XML that you have in a global
(without error checking code for simplicity):

on mouseUp
  global gMyXMLData  -- holds the XML data you want to examine
  put XMLLoadData(gMyXMLData) into tDocNum
  put XMLGetRoot(tDocNum) into tRootNode
  put XMLGetChildren(tRootNode) into tKidNodeList
  put "" into tKids
  repeat for each line tKidNode in tKidLNodeList
    put XMLGetNodeName(tKidNode) & cr after tKids
  end repeat
  answer "The child nodes are: " & cr & tKids
end mouseUp

This seems a bit onerous if my stack never loads an external XML doc.
