RE: Using XSLT for SAP R/3 IDocs Transformation

If you have a way to convert between real IDoc and the "XML version", you
should be able to define a stylesheet to transform between different XML
representations fairly easily (although with large amounts data you'd
probably want to either split your data stream into multiple XML documents
prior to tranformation, or use estensions like saxon:preview for memory
management). The tricky part is to convert between non-XML and XML.

It's possible (although probably not too much fun) to go from XML to a flat
data standard like IDoc using XSLT. It is virtually impossible to use pure
XSLT to convert from custom flat data to XML, although some limited support
can be provided using XSLT extensions. http://www.unicorn-enterprises.com/
XSLT processor does this.

If you need a solution for that, there are various other tools that can help
you to different degrees. You can just use a good RegEx language like Perl
or Omnimark or Python, or Java with a RegEx package (e.a.
http://www.savarese.org/oro/ ), or define a grammar for your data using a
compiler compiler like http://www.antlr.org or
http://www.metamata.com/javacc, or parse it with
http://www.unidex.com/xflat.htm

There are also some enterprise-level tools that specialize in data
conversion and B2B integration. <plug> Netfish XDI Server,
http://www.netfish.com/products/, can convert data between many different
standards, XML and non-XML, as well as do many other things with it. We have
an SAP adapter among many others.</plug>
