BlueButton.js helps developers parse and generate complex health data formats like C-CDA with ease, so you can empower patients with access to their health records. Try the demo.

BlueButton.js supports a few different health data types, like C32 and CCDA. To parse a health document, pass the source data to BlueButton:

var myRecord = BlueButton(xml);

BlueButton.js will detect the document type and choose the appropriate parser. The returned object has the following properties:

myRecord.type    // The document type
myRecord.source  // The parsed source data with added querying methods
myRecord.data    // The final parsed document data

See http://www.bluebuttonjs.com/docs/ for an explanation of the data sections, much more detailed sample code, instructions on how to generate a build, etc.
