[jira] Created: (XERCESC-1581) anyURI spaces rejected, while RFC allows them

anyURI spaces rejected, while RFC allows them
---------------------------------------------

         Key: XERCESC-1581
         URL: http://issues.apache.org/jira/browse/XERCESC-1581
     Project: Xerces-C++
        Type: Bug
  Components: Validating Parser (Schema) (Xerces 1.5 or up only)  
    Versions: 2.7.0    
 Environment: Windows XP, Linux, Mac OSX Tiger
    Reporter: Chris Storah


When validating an instance document based on a schema that uses the xs:anyURI datatype, spaces cause a validation error to be thrown (and the following message is displayed):

   Message: Datatype error: Type:InvalidDatatypeValueException, Message:Value 'urn:abc:v1 schema.xsd' is NOT a valid URI .


Although the schema specification says spaces should be avoided, in this case the document is coming from an external source so spaces are used.
See http://www.w3.org/TR/xmlschema-2/#anyURI

As the URI validation code calls XMLUri::isValidURI, the problem can be emulated using the code:
XMLCh* test = X("urn:abc:v1 schema.xsd"); // fails
//XMLCh* test = X("urn:abc:v1%20schema.xsd"); // works
bool valid = XMLUri::isValidURI(true, test);

Also, I notice that Xerces-J had a similar problem:
http://issues.apache.org/bugzilla/show_bug.cgi?id=18785

Is this a bug?
If not, is there anyway around this problem - apart from replacing spaces with their escaped versions prior to parsing?

Chris

Thom Bartold commented on XERCESC-1581:
---------------------------------------

This issue has still not been resolved in xerces-c version 2.8.0. It has apparently been resolved in xerces2-j 2.9.1.

If this issue were resolved in 2.7.0, it should have been correct in version 2.8.0.
