http://issues.apache.org/bugzilla/show_bug.cgi?id=27949 Schema xs:pattern value does not correctly handle [-xxx] or [xxx-] Summary: Schema xs:pattern value does not correctly handle [-xxx] or [xxx-] Product: Xerces2-J Version: 2.6.2 Platform: Other OS/Version: Other Status: NEW Severity: Minor Priority: Other Component: XML Schema datatypes AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Overall Description Xerces-2 does not correctly handle leading or trailing - characters in character sets, but requires the addition of an escape character \. Steps to reproduce Validate the xml: <Test Sign="-"/> Using the schema: <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";> <xs:element name="Test"> <xs:complexType> <xs:attribute name="Sign" type="Pattern" use="required"/> </xs:complexType> </xs:element> <xs:simpleType name="Pattern"> <xs:restriction base="xs:string"> <xs:pattern value="[+-]"/> </xs:restriction> </xs:simpleType> </xs:schema> The parser gives the error "InvalidRegex: Pattern value '[+-]' is not a valid regular expression. The reported error was: ''-' is an invalid character range. Write '\-'.'. According to http://www.w3.org/TR/xmlschema-2/#dt-charrange "The - character is a valid character range only at the beginning or end of a ·positive character group·." So the - character should not need to be escaped if it is next to a square bracket. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
