Parsing EDIFACT can be a daunting undertaking. How can I correctly create the syntactically and semantically correct tree from an EDIFACT file?

Answer 1

www.smooks.org - A template-based text parser. They have suitable EDI examples that I was looking to use to implement for Walmart 810s before they dumped my products.

Answer 2

try: http://bots.sourceforge.net not so much a library, but translates edifact to the format you prefer....xml....csv....etc

Answer 3

Parsing EDIFACT is easy. You can find many libraries to do it. For example,

http://code.google.com/p/edicoder/

All these libraries simply break up the messages into segments.

The hard part with EDIFACT is to transform the message into some meaningful objects. This is very application specific and I doubt you will find any libraries. Even if you find one, it will be specific to a narrow field, like hotel reservation.

Answer 4

We have implemented 834 EDI to XML using Java + Smooks 1.6. It s awesome!

Answer 5

There is a good one at http://x12parser.codeplex.com. It will output any 810 as xml, html or back to text with whitespace for easier inspection. The unit tests includes a sample of the Walmart 810 from the site: http://www.jobisez.com/edi/tp/guide.aspx?doc=/edi-igs/Walmart/810Invoice5010.pdf.

The formatted text would look like this:
