If you are using the Xerces parser you can explicitly override any included
schema reference in the XML with your reference (the one pulled from the
database). The actual function is setExternalSchemaLocation() or
setExternalNoNamespaceSchemaLocation() as the case may be. Since you have
the Schema in a database (as opposed to an URL) you will want to implement
the resolveEntity() method of the EntityResolver handler.

Subject: RE: [xml-dev] Including Schema inside the XML
Thank you very much Joe,
I am working on an application, that pulls the schema from a database
and validates an incoming XML message against the schema. The DTD and then
the XML are added to a stream and submitted to the parser. I want to do the
same with the schema.
Thank you,
Naren

> You can include the location of the schema and its associated
targetNamespace at the top of the instance document as follows:

> <?xml version="1.0"?>
> <Invoice
xmlns:xmlns:xsi="<http://www.w3.org/2001/XMLSchema-instance>"
> xsi:schemaLocation="<http://www.acme.org/invoices>"
> InvoiceV1.xsd>

> where xsi:schemaLocation indicates the targetNamespace of the schema whose
name is given in the second parameter. This indicates that the schema named
InvoiceV1.xsd (assumed here to be in the same directory as the instance
document, which may not always be the case) has a targetNamespace of
"<http://www.acme.org/invoices>".

> If the schema does not have a targetNamespace, the declaration would look
as follows:

> <?xml version="1.0"?>
> <Invoice
xmlns:xmlns:xsi="<http://www.w3.org/2001/XMLSchema-instance>"
> xsi:noNamespaceSchemaLocation="InvoiceV1.xsd>

> For more information on targetNamespace (and namespaces in general), you
can reference chapter 3 of the W3C Schema Primer:

could do this with DTDs and I now need to work with schemas. Thanks for the
help!
