I am using JAXP to parse and validate XMLs using XSD. I am able to do that. I need to store the data type of attributes. Is there any way to do so using JAXP?
My code Is as below...
SchemaFactory factory = SchemaFactory.newInstance(language);
schema = factory.newSchema(new StreamSource("test.xsd"));
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setSchema(schema);
DocumentBuilder db =dbf.newDocumentBuilder();
db.setErrorHandler(new DefaultHandler());
Document dom = db.parse(new File("test.xml"));
Element root = dom.getDocumentElement();
System.out.println("Node Name: " + root.getNodeName()+ " Node Value: " + root.getNodeValue());
TypeInfo type =root.getSchemaTypeInfo();
System.out.println("Root : " + type + type.getTypeName());
Attr a =root.getAttributeNode("orderid");
type = a.getSchemaTypeInfo();
System.out.println("Attr : " + type.toString() + " Type: " + type.getTypeName());
XML Input:
<?xml version="1.0" encoding="ISO-8859-1"?>
<shiporder orderid="889923">
<orderperson>John Smith</orderperson>
<shipto>
<name>Ola Nordmann</name>
<address>Langgt 23</address>
<city>4000 Stavanger</city>
<country>Norway</country>
</shipto>
<item>
<title>Empire Burlesque</title>
<note>Special Edition</note>
<quantity>1</quantity>
<price>10.90</price>
</item>
<item>
<title>Hide your heart</title>
<quantity>1</quantity>
<price>9.90</price>
</item>
</shiporder>
XSD:
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="shiporder">
<xs:complexType>
<xs:sequence>
<xs:element name="orderperson" type="xs:string"/>
<xs:element name="shipto">
<xs:complexType>
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="address" type="xs:string"/>
<xs:element name="city" type="xs:string"/>
<xs:element name="country" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="item" maxOccurs="unbounded">
<xs:complexType>
<xs:sequence>
<xs:element name="title" type="xs:string"/>
<xs:element name="note" type="xs:string" minOccurs="0"/>
<xs:element name="quantity" type="xs:positiveInteger"/>
<xs:element name="price" type="xs:decimal"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute name="orderid" type="xs:string" use="required"/>
</xs:complexType>
</xs:element>
</xs:schema>
Output I am getting is:
Node Name: shiporder Node Value: null
Root : [shiporder: null]null
Attr : orderid="889923" type null
If you're using SAX parsing (ValidatorHandler
), you want ValidatorHandler.getTypeInfoProvider().getAttributeTypeInfo()
. If you're using DOM parsing you want Attr.getSchemaTypeInfo()
.
