Follow up: I verified that an absolute URI is resolved via a catalog for both namespace and no-namespace cases, e.g.: xsi:noNamespaceSchemaLocation="urn:schema:simpletest_nons.xsd" Mapped thus: <system systemId="urn:schema:simpletest_nons.xsd" uri="simpletest_nons.xsd" /> I suspect this is simply representative of how Xerces (broken) implementation of schema location resolution works. [It is broken because it uses SYSTEM resolution calls to resolve schema locations, rather than URI resolution calls. I reported a bug a while ago and the response was "we're not going to fix it, it's too deep in the code". I looked at the code and concur that it would be a non-trivial fix. Nevertheless, it's still wrong.] Cheers, E. -- Eliot Kimber Senior Solutions Architect "Bringing Strategy, Content, and Technology Together" Main: 610.631.6770 www.reallysi.com www.rsuitecms.com

Hi Eliot, oXygen supports XML Catalogs 1.1 and you can resolve the schema based on its suffix, so you can have something like: <systemSuffix systemIdSuffix="simpletest_nons.xsd" uri="simpletest_nons.xsd"/> that should solve all schema locations ending in simpletest_nons.xsd to the simpletest_nons.xsd from the same folder as your catalog file.

I'm trying to figure out how or if its possible to validate a schema-based document against a schema where the system location is a relative URI resolved through a catalog.

Here's my document element:

<document xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="simpletest_nons.xsd">

This document validates when it's in the same directory as the schema.

Here is my catalog:

<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog" prefer="public"> <system systemId="simpletest_nons.xsd" uri="simpletest_nons.xsd" /> <uri name="simpletest_nons.xsd" uri="simpletest_nons.xsd" /> <uri name="urn:simpletest.gidi.org" uri="simpletest.xsd" /> </catalog>

When I try to validate the above document stored in a location separate from the schema, validation fails with messages to the effect that it can't find the schema, with an effective URI that reflects the location of the document.

Actually I get the same sort of failure for a namespaced document valid against a namespace-governing schema, e.g.:

<document xmlns="urn:simpletest.gidi.org" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:simpletest.gidi.org simpletest.xsd">

Is it possible to use catalogs to remap non-absolute URIs in this way or must I use absolute URIs for the schema location value?

Thanks,
