> Key: XERCESJ-1456
> URL: https://issues.apache.org/jira/browse/XERCESJ-1456
> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema 1.0 Datatypes
> Affects Versions: 2.10.0
> Environment: JDK 1.5.0
> Reporter: Christian Schröder
> Assignee: Khaled Noaman
> Fix For: 2.11.0
>

> I have the following schema:
> <?xml version="1.0" encoding="UTF-8"?>
> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
> <xsd:element name="test" type="Test"/>
> <xsd:simpleType name="Test">
> <xsd:restriction base="xsd:string">
> <xsd:pattern value="[0-9]{0,3}([0-9]{3})*"/>
> </xsd:restriction>
> </xsd:simpleType>
> </xsd:schema>
> And this xml file:
> <?xml version="1.0" encoding="windows-1252"?>
> <test>1010000</test>
> I try to validate the file with the following test code:
> DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
> dbf.setNamespaceAware(true);
> DocumentBuilder builder = dbf.newDocumentBuilder();
> Document xsd =
> builder.parse(Main.class.getResource("/test.xsd").toString());
> SchemaFactory sf =
> SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
> Schema schema = sf.newSchema(new DOMSource(xsd));
> Validator validator = schema.newValidator();
> Document test =
> builder.parse(Main.class.getResource("/test.xml").toString());
> validator.validate(new DOMSource(test));
> I get an org.xml.sax.SAXParseException: cvc-pattern-valid: Value '1010000' is
> not facet-valid with respect to pattern '[0-9]{0,3}([0-9]{3})*' for type
> 'Test'.
> In my opinion, the given value should be valid for the given pattern. Even
> the following code prints "true":
> RegularExpression re = new RegularExpression("[0-9]{0,3}([0-9]{3})*");
> System.out.println(re.matches("1010000"));
