Hi Chaps, I am having some problems with XMLGrammarPool and I would like to confirm the cause of this.
I think that it is because I have a number of different XML documents that use different XML Schemas, and these all use the same namespace i.e. no namespace. When I create a new XMLGrammarPool and validate document A with Schema 1 it works, however when I then validate document B with Schema 2 using the same XMLGrammarPool it fails as it cant find the Schema. Both document A and document B have no namespace defined. e.g. <a xsi:noNamespaceSchemaLocation="1.xsd" xmlns:xsi="xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> ... </a> <b xsi:noNamespaceSchemaLocation="2.xsd" xmlns:xsi="xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> ... </b> Our application needs to validate a number of different incoming XML documents using their XML Schemas, a number of these documents all have no namespace and use xsi:noNamespaceSchemaLocation="blah.xsd" to refer to their Schemas. I would like to use an XMLGrammarPool for caching Schemas to improve performance of the system. I thought that by implementing my own XMLGrammarPool I would be able to determine the uniqueness of an XMLSchema by something other than its namespace, e.g. its location. However this doesn't seem to be the case. After some investigation with the debugger: at line 1373 of XMLSchemaValidator in com.sun.org.apache.xerces.internal.impl.xs (Sun JDK 1.6.0_06) I see this comment in reset(XMLComponentManager componentManager) - // store the external schema locations. they are set when reset is called, // so any other schemaLocation declaration for the same namespace will be // effectively ignored. because we choose to take first location hint // available for a particular namespace. My question then is how and what do I need to do to get this working? Or if it is currently possible, then what am I doing wrong?
