XML Schema
<?xml version="1.0" encoding="UTF-8"?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <xsd:element name="customer" type="customer-type"/> <xsd:complexType name="customer-type"> <xsd:sequence> <xsd:element name="picture" type="xsd:hexBinary"/> <xsd:element name="resume" type="xsd:base64Binary"/> </xsd:sequence> </xsd:complexType> </xsd:schema>
Code Sample
XMLDirectMapping pictureMapping = new XMLDirectMapping(); pictureMapping.setAttributeName("picture"); pictureMapping.setXPath("picture/text()"); XMLField pictureField = (XMLField) pictureMapping.getField(); pictureField.setSchemaType(XMLConstants.HEX_BINARY_QNAME);
Mapping to a Union Field:
XML Schema
<?xml version="1.0" encoding="UTF-8"?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <xsd:element name="customer" type="customer-type"/> <xsd:complexType name="customer-type"> <xsd:sequence> <xsd:element name="shoe-size" type="size-type"/> </xsd:sequence> </xsd:complexType> <xsd:simpleType name="size-type"> <xsd:union memberTypes="xsd:decimal xsd:string"/> </xsd:simpleType> </xsd:schema>
Code Sample
XMLDirectMapping shoeSizeMapping = new XMLDirectMapping(); shoeSizeMapping.setAttributeName("shoeSize"); XMLUnionField shoeSizeField = new XMLUnionField(); shoeSizeField.setXPath("shoe-size/text()"); shoeSizeField.addSchemaType(XMLConstants.DECIMAL_QNAME); shoeSizeField.addSchemaType(XMLConstants.STRING_QNAME); shoeSizeMapping.setField(shoeSizeField);
Preserving the Node Type: If the type of a node is not defined in your XML schema, you can configure an XML Direct Mapping to use the xsi:type attribute to provide type information.
Code Sample
XMLDirectMapping numberMapping = new XMLDirectMapping(); numberMapping.setAttributeName("number"); numberMapping.setXPath("number/text()"); XMLField numberField = (XMLField) numberMapping.getField(); numberField.setIsTypedTextField(true);
More Information: For more information about using the XML Direct Mapping, see the "Understanding XML Mappings" chapter of the Oracle TopLink Developer's Guide. @since Oracle TopLink 10g Release 2 (10.1.3)
