LocalName is returning empty string, though namespace is defined


XML

<em:Employees  xmlns:em="http://www.example.com">
    <em:Employee id="1">
        <age>29</age>
        <name>Pankaj</name>
        <gender>Male</gender>
        <role>Java Developer</role>
        <childrens>
            <child>
                <age>2</age>
                <name>Guptha</name>
                <gender>Male</gender>
            </child>
        </childrens>
    </em:Employee>
</em:Employees>

Java

import java.io.File;
import java.io.IOException;
import java.util.List;

import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

import org.xml.sax.SAXException;

public class XMLParserSAX {

    public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException {
        SAXParserFactory saxParserFactory = SAXParserFactory.newInstance();
        SAXParser saxParser = saxParserFactory.newSAXParser();
        MyHandler handler = new MyHandler();
        saxParser.parse(new File("src/Resources/employees.xml"), handler);
        //Get Employees list
        List<Employee> empList = handler.getEmpList();
        //print employee information
        for (Employee emp : empList)
            System.out.println(emp);
    }
}

In my DefaultHandler, when I'm implementing startElement(), localName is empty, and qName contains the namespace including the name, ex. em:Employees.

If I'm not mistaken, localName should give me back the name without the namespace. Am I doing something wrong?


Solution

  • Try making the SAXParserFactory namespace aware:

        SAXParserFactory saxParserFactory = SAXParserFactory.newInstance();
        saxParserFactory.setNamespaceAware(true);
        SAXParser saxParser = saxParserFactory.newSAXParser();
    

    Read the details of startElement() here. You'll see that localNameisn' defined unless the parser is aware of namespaces.
