http://issues.apache.org/bugzilla/show_bug.cgi?id=30802 Getting org.xml.sax.SAXParseException: cvc-complex-type.3.1 while parsing XML with elements having same name but different complex types Summary: Getting org.xml.sax.SAXParseException: cvc-complex- type.3.1 while parsing XML with elements having same name but different complex types Product: Xerces-J Version: 1.4.4 Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: Other Component: SAX AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] I created an XSD which contains elements with same name but different complex types. For example, the high level XSD looks like - <xs:element name = "Field" type = "ComplexType1"> <xs:element name = "Field" type = "ComplexType2" minOccurs=0> <xs:element name = "Field" type = "ComplexType3"> - while the corresponding XML would be - <Field type="Field1"> <Field type="Field2"> <Field type="Field3"> If I validate this XML against the XSD it works fine. But if I remove the second element from the XML as shown below as it's minOccurs = 0 <Field type="Field1"> <Field type="Field3"> and try to validate it against the XSD it throws an exception as shown below org.xml.sax.SAXParseException: cvc-complex-type.3.1: Value 'Field3' of attribute 'name' of element 'Field' is not valid with respect to the corresponding attrib ute use. Attribute 'name' has a fixed value of 'Field2'. But this works fine with XML SPY without any problems. Could you please let me know why it's happening and is it a bug in Xerces? If it's a bug then is there a work around for this? I am pasting the Actual XSD and XML below for your reference XSD: <?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:mm2="mm2" xmlns:xs="http://www.w3.org/2001/XMLSchema"; targetNamespace="mm2" attributeFormDefault="unqualified" elementFormDefault="qualified"> <xs:element name="Test_element" type="mm2:Test_Type"> </xs:element> <xs:simpleType name="SHORT_TEXT255_Type"> <xs:restriction base="xs:string"> <xs:maxLength value="255"/> </xs:restriction> </xs:simpleType> <xs:complexType name="Test_Type"> <xs:sequence minOccurs="0" maxOccurs="1"> <xs:choice minOccurs="1" maxOccurs="1"> <xs:element minOccurs="0" name="Field" maxOccurs="1"> <xs:complexType> <xs:simpleContent> <xs:extension base="mm2:SHORT_TEXT255_Type"> <xs:attribute type="xs:string" fixed="Field1" name="name"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> </xs:choice> <xs:choice minOccurs="0" maxOccurs="1"> <xs:element minOccurs="0" name="Field" maxOccurs="1"> <xs:complexType> <xs:simpleContent> <xs:extension base="mm2:SHORT_TEXT255_Type"> <xs:attribute type="xs:string" fixed="Field2" name="name"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> </xs:choice> <xs:choice minOccurs="1" maxOccurs="1"> <xs:element minOccurs="1" name="Field" maxOccurs="1"> <xs:complexType> <xs:simpleContent> <xs:extension base="mm2:SHORT_TEXT255_Type"> <xs:attribute type="xs:string" fixed="Field3" name="name"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> </xs:choice> </xs:sequence> <xs:attribute type="xs:string" fixed="Test" name="type"/> </xs:complexType> </xs:schema> XML: <?xml version="1.0" encoding="UTF-8"?> <!--Sample XML file generated by XMLSPY v5 U (http://www.xmlspy.com)--> <Test_element xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns="mm2"> <Field name="Field1">String</Field> <Field name="Field3">String</Field> </Test_element> Exception thrown by Parser (thrown for both SAX and DOM parsing): org.xml.sax.SAXParseException: cvc-complex-type.3.1: Value 'Field3' of attribute 'name' of element 'Field' is not valid with respect to the corresponding attrib ute use.
