Solving a multiple schema definiton problem

Hello,

Our problem is the same old multiple schema definiton case:

            Cannot locate document specification because multiple schemas matched the message type COMPANY_CONFIRMATION.

..which actually is not a problem on the Biztalk side because it uses the root node and namespace to uniquely identify the type of the message.

Our case is simple, we receive different types of xml files to a single location. The file naming convention is same for all these files so we cannot filter them by name or extension.

We're using the schema generator to produce the schemas.

The xml files we receive share the same root node name. They only differ by their InstrumentType attribute.

There's also no namespace information within the file.

Here are three sample root nodes:

<COMPANY_CONFIRMATION InstrumentClass="FX" InstrumentType="TYPE1">

<COMPANY_CONFIRMATION InstrumentClass="FX" InstrumentType="TYPE2">

<COMPANY_CONFIRMATION InstrumentClass="FX" InstrumentType="TYPE3">

We tried several things such as the custom pipeline solution by producing and applying different schemas to the incoming files during the disassemble phase. We also set different target namespaces for each schema hoping that the disassembler would match the suitable schema with the file.

We also set the InstrumentType fixed property of the attributes respectively as TYPE1, TYPE2, TYPE3.

Since none of these worked, the question comes along: Is there any way we can tell Biztalk to match the file to an appropriate schema when there's no namespace information within the files and the root node names are the same? Using the provided Biztalk 2006 tools?

Thanks and regards.

Emre.
