[xsd-users] Schema Validation

[Balasubramanyam, Shivakumar]

Boris,

The use case below worked as long as I have only one schema file that
had a unique namespace.

In our case, we have multiple schemas which has same target namespace.

How do we solve this case? When I tried, I think it overwrote the
mapping information. 

It is possible to register multiple schema files for same namespace?

Thanks,
Shiva

Let's say schemafile1.xsd is in the http://www.example.com/namespace1
namespace and schemafile2.xsd is in http://www.example.com/namespace2.
Then you can do the following:

xml_schema::properties props;

props.schema_location (
  "http://www.example.com/namespace1",
  "file:////opt/schemas/namespace1/namespace2/schemafile1.xsd");

props.schema_location (
  "http://www.example.com/namespace2",
  "file:////opt/schemas/namespace1/namespace2/schemafile2.xsd");

root ("file.xml", 0, props);

Here 'root' is the parser function for the document root. Note
that the above schema location properties override the schema
location information specified in the XML documents.
