I m looking for any helpful links or advice on translating an incoming EDI 940 (X12) to a (|) Pipe delimited flat file in c#.net
My technique might seem quite heavy for a one shot translation, but here it is:
Step #1: X12 ------------- [Pre-Parsing Program] ---> X12 syntax XML
Step #2: X12 syntax XML--> [940 Parsing XSLT] ------> 940 XML
Step #3: 940 XML --------> [Mapping XSLT] ----------> your FF XML
Step #4: your FF XML ----> [Serialising XLST] ------> your FF
Step #1: The "X12 syntax XML" is a very simple grammar showing only the SYNTAX of X12, thus the [Pre-Parsing Program] is extremely simple, and can be used for any X12.
Step #2: The "940 XML" has a grammar which fully explicit the structure of the 940. The [940 Parsing XSLT] is where you express the specific structure of an 940.
Step #3: The [Mapping XSLT] transforms the 940 structure into the structure of your FF, expressed in XML.
Step #4: Finally, the [Serialising XLST] creates your FF based on its XML-ized version.
The main advantage of this architecture is its (1) openness - main parts are in XSLT that can be performed with any programming language using a variety of XML/XLST library, and its (2) scalability, at the end, you transform any format into any format ;-)
If you could upload somewhere a simple sample instance of a 940 message AND its translation into your FF structure - that you should do manually with Notepad ;-) - I might have the time to illustrate my technique - at least giving you the 3 XLST scripts needed ;-)
Converting an EDI message to a flat file is a bad idea, you are probably going to loose data and message meaning. That s why EDI exists in the first place
