Parsing CDA hl7 documents

Question

I am working on a project that provides some CDA hl7 documents, parses and extracts data, and stores it in a database. I cannot find a good parser / library that reads CDA (XML) and returns different sections. Any idea what is the best way to approach this? I'm new to healthcare technology, so maybe something is missing? But I can’t imagine that there is no library that parses the CDC for an object?

Answer 1

MDHT https://www.projects.openhealthtools.org/sf/projects/mdht/ The Java API creates, consumes and validates a CDA document

Answer 2

HAPI is an open source library in Java that provides support for parsing messages to an HL7 object and vice versa

http://hl7api.sourceforge.net/

Answer 3

There is also an Everest structure ( http://everest.marc-hi.ca ) that can analyze any instance of HL7v3 (CDA is a v3-based standard). Its for .NET and Java, although .NET works better and more mature.

Answer 4

This is a C-CDA competition sponsored by HL7 ( http://www.hl7.org/events/toolingchallenge.cfm ) Winners will be announced in September 2016, I am sure there will be many samples of C-CDA parser for you to choose from .
