Updated: (XERCESJ-1211) Use of DOMInputSource causes null entries in XSNa 2006-11-09 - By Chris Simmons (JIRA)
[ http://issues.apache.org/jira/browse/XERCESJ-1211?page=all ]
Chris Simmons updated XERCESJ-1211:
-----------------------------------
Attachment: NullSchemaLocations.zip
A simple application showing the problem.
There are two schemas, one including the other. The application loads the
schema grammar and prints out the document locations to standard out.
I'd expect to see two distinct URI's but there's one URI and a null entry.
> Use of DOMInputSource causes null entries in XSNamespaceItem
.getDocumentLocations().

> Key: XERCESJ-1211
> URL: http://issues.apache.org/jira/browse/XERCESJ-1211
> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema API
> Affects Versions: 2.8.1
> Environment: Linux.
> Reporter: Chris Simmons
> Priority: Minor
> Attachments: NullSchemaLocations.zip

> I've written a test which I will shortly attach where I load a schema grammar
using DOMInputSource. The resulting schema grammar's document locations list
contains a null entry.
> I think this is due to the different code path followed when using dom inputs
. The normal path loads the schema from a stream and hits the following code in
XSDHandler.getSchemaDocument():-
> // now we need to store the mapping information from system id
> // to the document. also from the document to the system id.
> if (key != null)
> fTraversed.put(key, schemaElement );
> if (schemaId != null)
> fDoc2SystemId.put(schemaElement, schemaId );
> fLastSchemaWasDuplicate = false;
> return schemaElement;
> The document isn't being put in fDoc2SystemId when using DOMInputSource.
Perhaps it would be more robust if XSDHandler was responsible for dealing with
dom inputs, and just directly used the dom when it normally parses the XML?
> I need the document locations field in order to figure out which documents a
schema grammar depends upon, in case some are modified or reloaded.
