Thanks for the quick reply.

I wish I only had to dump out the content of the node. The hope is, that 
I can encrypt entire subtrees of a document and store this encrypted 
block as a text node for the subtree's parent. I guess I'll just go 
through the text by hand and search/replace the xml markup entities.
