2.13. EDI to SAX
The EDI to SAX event mapping process is based on a mapping model supplied to the EDI reader. (This model must always use the http://www.milyn.org/xsd/smooks/edi-1.2.xsd schema. From this schema, you can see that segment groups are supported, including groups within groups, repeating segments and repeating segment groups.)
The medi:segment element supports two optional attributes, minOccurs and maxOccurs. (There is a default value of one in each case.) Use these attributes to control the characteristics of a segment. A maxOccurs value of -1 indicates that the segment can repeat any number of times in that location of the (unbound) EDI message.
You can add segment groups by using the segmentGroup element. A segment group is matched to the first segment in the group. They can contain nested segmentGroup elements, but the first element in a segmentGroup must be a segment. segmentGroup elements support minOccurs and maxOccurs. They also support an optional xmlTag attribute which, if present, will result in the XML generated by a matched segment group to be inserted into an element that has the name of the xmlTag attribute value.
