Bjorn, if you want to insert nodes, then I'd recommend going straight to
the script component, or alternatively create your own custom DSC JAR
that allows you to insert, and remove nodes. If you do know how many
nodes you have in your XML, adding a node via /VariableName/NodeName[1]
will create a new node for you. Again, custom DSC will allow you much
more flexibility when it comes to manipulating XML.
