xmlNamespaceConvert.py
Language: Python 2.7

This program changes the namespace format for XHTML files so EPUBs will
validate with the Google Play store. One use for this is if you edit EPUBs
using Python's elementTree module, which messes with namespaces.

This program changes the format from: '<html:[tag]>' to simply <tag> and makes the appropriate change
to the namespace declaratio.n
