Re: Element creation

Kjell,

Thanks for your response. It works fine using the import_node.
I have another question. Does the document object deletes the memory
for all the child nodes, when it goes of our scope or do i need to keep
track of all the node pointers and delete it by myself?

regards,
Jaya
