CDA: Consume Document

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:

How it works [top]

  • 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
