Looking for a tool/library to convert XML to X12 (270 - medical eligibility request) and then to convert the X12 response (271 - eligibility response) back to XML. This will be embedded in a server application (will consider any target language). I've toyed with idea of writing my own X12 parser and generator but this project will most likely expand to other X12 transactions and I'd like to find a solution that will be extensible.
I ended up creating my own XML <-> x12 transformation tool. There were some commercial offerings that I came across (one of which, from EtaSoft, is worth checking out for their fine documentation) but ultimately the advantage of a homegrown solution was too great.
I did use the configuration files from X12::Parser as the basis for an X12 parser, essentially turning the config file into code and eliminating the overhead and error handling for managing configuration files that should in theory almost never change.
