Problems Validating XML against Schema

[Avinash Ga]

hi ranchers,


im getting exception while validating the xml against the schema.

xml file is like

persondetails.xml


<?xml version="1.0" encoding="UTF-8"?>
<person name="avinash" age="27" gender="male">
<address type="email">[e-mail]</address>
<address type="phone">khkhlll</address>
<address type="company">jgjhgjhgk</address>
</person>

persondetails.xsd

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.example.org/persondetails" xmlns:tns="http://www.example.org/persondetails" elementFormDefault="qualified">

<element name="person">
<complexType>
<sequence>
<element name="address">
<complexType>
<attribute name="type">
<simpleType>
<restriction base="string">
<enumeration value="email"></enumeration>
<enumeration value="phone"></enumeration>
<enumeration value="company"></enumeration>
</restriction>
</simpleType>
</attribute>
</complexType>
</element>
</sequence>
<attribute name="name" type="string"></attribute>
<attribute name="age" type="int"></attribute>
<attribute name="gender" type="string"></attribute>
</complexType>
</element>
</schema>


java code is :

package simplevalidator;

import javax.xml.XMLConstants;
import javax.xml.transform.stream.StreamSource;
import javax.xml.validation.Schema;
import javax.xml.validation.SchemaFactory;
import javax.xml.validation.Validator;

public class SchemaValidator {

/**
* @param args
*/
public static void main(String[] args) throws Exception {
SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = factory.newSchema(new StreamSource("src//persondetails.xsd"));
Validator validator = schema.newValidator();
validator.validate(new StreamSource("src//persondetails.xml"));
}

}


Exception is :

What is the difference between the following two attributes?

xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:tns="http://www.example.org/persondetails"

Hi Jim,

As im a newbie in XSD i created it using eclipse. The one posted here is exact one generated by eclipse. One of the yahoo answers says that namespace is related to SOAP.


Thanks
