Introduction

This example shows how to use the builtin xml.parse{} function to parse and consume a CDA document.

Note: The reason we are using XML functions to parse the CDA document is because CDA documents are simply large XML documents.

Using the Code [top]

Import the CDA: Consume Document channel from the Builtin: Iguana Protocols repository
Experiment with the code to find out how it works
Then add the local module to your Translator project
Copy the require statement from the channel and add it at the top of your script
Note: This local module uses require to return a single function
Adapt the code to your own requirements
Use xml.parse{} to parse a CDA
Note: The example code uses a sample CDA you will need to change this for a production system
Use ProcessProblems() to extract the list of problems from the CDA structured body

This is the github code for the main module:

The code uses the builtin xml.parse{} function to parse the CDA into an XML node tree
Note: Using XML functions to parse CDA documents works because CDA documents are simply XML documents, albeit large and complex ones
The code uses ProcessProblems() to extract the list of problems from the CDA body
- The ProcessProblems() function requires a structuredBody parameter
- ProcessProblems() is a local function stored in the local module problems.lua
