As a work-around, you can read the balanced chunk into a second document
using parseMemory, grab that doc's root element, then insert that where
needed in your original doc. Here's a brief example:


#!/usr/bin/python -u
import libxml2

chunk = "<foo><bar>content</bar></foo>"
doc2 = libxml2.parseMemory(chunk, len(chunk))
root2 = doc2.getRootElement()

doc1 = libxml2.newDoc("1.0")
root1 = doc1.newChild(None, "doc", None)
root1.addChild(root2)
print doc1.serialize(None,1)
