XML copy Element

Hi

I am working with XmlReader, XmlWriter, read from XML structure an write some of the nodes/tags. Especialy the readSubtree() is a usefull and fast method to copy nodes. If there are start elements like Envelope or Action is there a way to copy them in a single command?

Thanks for help.
