----------------------------------

             Summary: E_Regex only works with XSDstring.
                 Key: JENA-839
                 URL: https://issues.apache.org/jira/browse/JENA-839
             Project: Apache Jena
          Issue Type: Bug
          Components: ARQ
    Affects Versions: Jena 2.12.1
         Environment: Linux
            Reporter: Claude Warren
            Assignee: Claude Warren


E_Regex eval verifies the argument is a string using: 

Node arg = NodeFunctions.checkAndGetStringLiteral("REGEX", args.get(0)) ;

 NodeFunctions.checkAndGetStringLiteral verifies that if the nodevalue is not 
null and is an XSDstring by the following statement:

 if ( dt != null && !dt.equals(XSDDatatype.XSDstring) )
            throw new ExprEvalException(label + ": Not a string literal: " + 
nv) ;

this means that other string types (e.g. XSDnormalizedString) fail.

I believe that the check should be to check that dt is an instanceof 
XSDBaseStringType.

I am looking for comment before making the change.
