EDIReader is a Java package for parsing business documents structured according to EDI (Electronic Data Interchange) standards.
It supports the SAX and JAXP interfaces defined for XML, making it suitable for use in any XML-based system that allows the configuration of a custom SAX parser.
EDIReader parses EDI analogous to the way a conventional SAX parser parses XML, calling an arbitrary JAXP ContentHandler with elements and attributes as if it were parsing XML. Therefore, XSLT transformations and DOM-based tools can be applied directly to EDI input.
In many cases, EDIReader and an XSLT stylesheet provide a lightweight and open source alternative to conventional EDI mapper/translators.
Capturing an XML expression of the parsed EDI data is simple with EDIReader, and an EDItoXML utility is included as a demonstration program.
EDIReader is not a conventional EDI mapper/translator, nor by itself a replacement for one. Its purpose is to allow EDI input into a wide variety of XML-based systems so that tools used to transform and otherwise process XML-structured data can be applied to EDI as well. It requires no more configuration than any SAX parser, which is virtually none.
A design goal is to build in as much EDI awareness as is necessary to do its job and no more. Therefore, it handles all of the issues of EDI syntax so that XML tools such as XSLT can be applied to the issues of EDI structure and semantics. Since it does not need to perform full EDI compliance checking, it requires no tables of code values and the like to be installed and updated for particular EDI standards and versions.
