Python CCDA parsing engine

pyCCDA

This is a lightweight Python library for parsing raw C-CDA documents without the need to understand the entire specification. If you're using BlueButton.js this maintains much of the same functionality. This is a largely unstable build so use at your own risk - we have since ported over to C++ for necessary performance improvements and will release a stable version of that shortly.

Test documents from various vendors available here.

Install

pip install pyCCDA

Example Usage

# example
from pyCCDA import CCDA
with open('CCCD_sample.xml') as f:
   ccd = CCDA(f.read())
   # ccd.type   # The document type ('ccda', 'c32', and such)
   # ccd.source # The parsed source data (XML) with added querying methods
   # ccd.data   # The final parsed document data
name = ccd.data.demographics.name
print name.prefix, name.given, name.family
