Unwanted XML attribute

[Omega501]

I'm writing a small app for my own use (mostly to play with an XML datastore) I'm trying to add a node to the xml document. This works fine, except that it keeps on adding an empty xmlns attribute to the new nodes. Is there anyway of stopping this? I am contructing the xml node from a string

<NewNode>
<DataNode />
</NewNode>

and inporting it into the xml document like this. xmlContactsList["Root"].AppendChild(NewNode); But the result I keep getting is

<doctype tag>
<Root>
<NewNode xmlns="">
<DataNodes />
</NewNode>
</Root>

Is there anyway of getting rid of the xmlns attribute? The root node already has the correct value for this.
