There are different products on the market which are offer tools for
read EDI datastream and create XML code from it.
For example our XML/EDI converter work this way and use a
formatdescription which define the EDI data. Then the EDI data merged
with the formatdescription and create XML code. This then can be
translated to another XML structure via XSLT.
Also the back way for create EDI data from XML data is available with
the same formatdescription.
So this way the real mapping will be done only between XML<->XML!

It seems that this technologies used at many products now and this is
very good, because then you have a standard way for make EDI
conversions and the customer doesn't have to learn different
converter and after decide to use a special software vendor never can
change him! :))

The XSLT processors are still now much better and have no real
problems with performance.
We still convert files which are bigger then 1 MB by this way and it
work fine!
But by now youu can't use it for files which are much biger. If you
realy need to convert data which are about 100 MB, maybe you realy
have to look for other ways to handle them! :)
