This is some python code to parse an Energy Service Provider Interface (ESPI), or "Green Button" XML file into Python objects.

python greenbutton/parse.py testdata/green_button_data_1724106323848.xml

Run parse_feed() from the parse.py file to get a list of UsagePoint objects. From there you should be able to explore all of the data in the feed. Documentation is a little lacking at the moment, but the class members mostly match the names from the ESPI standard (or at least the XML entities).

There's a bit of documentation in the doc directory about the ESPI standard, mostly figured out from public sources and actual ESPI files.
