Copying Elements using PyXML

[Scott Yang]

Assuming you want to have the result DOM as
<xformimport>
    <docID />
    <document />
    <person>
        <name />
        ...
    </person>
</xformimport>

You should be able to do it easily using PyXML.

# Parse the XML document into DOM objects.
from xml.dom.ext.reader.PyExpat import Reader
person = Reader().fromString(doc1)
xformimport = Reader().fromString(doc2)

# Clone person's document node.
person_cloned = person.cloneNode(1, xformimport)

# Append cloned node to xformimport's child nodes.
xformimport.documentElement.appendChild(person_cloned)
