Hi Arnaud,
Thanks for you help.
Here is a simple example of my problem (sorry I dont think
that I expressed my problem well in words before, but hope
these files and output will make more sense). Ok, these are
the attachments:
1) ReadSchema.java
2) TestSchema.java
3) 2 schema versions (imsvdex_1.xsd, imsvdex_2.xsd)
4) output.txt
* I am sure you know this*, but I thought I will mention that you
will also require "xercesImpl.jar" when running the program.
The "output.txt" shows the outputs when using the 2 different
versions of the same schema.
Thank you,
Tina
