xml - DFDL Parsing for x9.2 specification message -


hi have requirement like: there x9.2 specification message e.g.

header format 97xx message 

data item     field name     attribute 006           msg.type       4 n 001           msg.from       6 chr 015           msg.reply      1 chr 017          msg.trace       6 n 002           msg.date       8 n 003           msg.time       4 n 004           msg.session    6 n 009           msg.member     11 n 018           msg.record     7 n  9701 access authorization request standard header data item     field name     attribute 133           msg.hbac       8 n 230           msg.disclaimed 1 char    need convert xml using dfdl. sample xml      <root>     <header>     <msg.type></msg.type>     .     .     .     .     <msg.record></msg.record>     </header>     <body>     <msg.hbac></msg.hbac>     <msg.disclaimed></msg.disclaimed>     </body>     </root>

the problem x9.2 specification messages can have different fields different message type above example 9701.

but 9702 have different set of data item. how write dfdl parser can parse message type whether 97xx series or 95xx series or other series of x9.2 specification.

i have never worked specific format. dfdl model accommodates possibility of different message types choices (points of uncertainty) , uses either discriminators or initiators resolve choices. begin reading link background. go here , pdf lab 6.
