I've created a workflow to convert clinical codes to a flat "code to description" CSV for further linking. The data comes natively in XML and I'm converting it to JSON and then quite a lot of transposing to get it into CSV. My question is can this be done better, using only KNIME nodes (no code snippets to keep it as transparent as possible) and directly from XML rather than going through JSON. Specifically I would want to replace the Perl Snippet although this very efficiently does the job.
The input file is available in this zip file: https://www.cms.gov/Medicare/Coding/ICD10/Downloads/2017-ICD10-Code-Tables-Index.zip
My workflow is attached.
