libxml TxmlDoc.newDoc()

hi there. I have a question: How can I create a completely new xml file using the libxml module?

I fine with reading xml files, but now I want my program to create a new one (to save some player profiles).

So I started with:

doc:TXmlDoc = TXmlDoc.newDoc("1.0")
...
doc.saveFile(profiles.xml)

But there is no root node in the doc, and I dont know how to get one in ther since I just see a command node.addChild(), but not doc.addRootNode() or something like that.

Anybody here who can help me?

Edit:

I found it out:

node:TXMLNode = TXMLNode.newNode("typename")
doc.setRootElement(node)
