Bad XS:pattern interpretation for XSD
-------------------------------------

         Key: XERCESC-1512
         URL: http://issues.apache.org/jira/browse/XERCESC-1512
     Project: Xerces-C++
        Type: Bug
  Components: Validating Parser (Schema) (Xerces 1.5 or up only)  
    Versions: 2.6.0    
 Environment: Windows 2000 SP4, VC 6 SP4 used to compiled the xerces libraries 
(C++ & Perl).
I call the Xerces library from perl with the XML::Xerces - perl glue library
    Reporter: Olivier Quintens


Hi,

The code validates xml messages against a enterprise standard XSD.
The following structure defines the tag validation
<xs:element name="ENTRY_TIME_STAMP" type="typeDateSeconds" minOccurs="0"/>
.....
<xs:simpleType name="typeDateSeconds">
      <xs:restriction base="xs:string">
             <xs:pattern value="[0-9]{14}|[0-9]{16}"/>
      </xs:restriction>
</xs:simpleType>

When the tag ENTRY_TIME_STAMP contains a value which match the first part 
([0-9]{14}), the xml is considered as valid.
e.g : <ENTRY_TIME_STAMP>20051006082856</ENTRY_TIME_STAMP>

When the tag ENTRY_TIME_STAMP contains a value which match the first part 
([0-9]{16}), the validator parser failed
e.g : <ENTRY_TIME_STAMP>2005100608285631</ENTRY_TIME_STAMP> 

Threturn error is  like 
Reason :
ERROR:
FILE:    FAKE_SYSTEM_ID
LINE:    1
COLUMN:  211
MESSAGE: Datatype error: Type:InvalidDatatypeValueException, Message:Value 
'2005100608285631' does not match regular expression facet 
'([0-9]{14}|[0-9]{16})'.

Cheers

Olivier
