Question

I’m reading a XML file same as below:

<ts>
    <tr comment="" label="tr1">
        <node order="1" label="" />
    </tr>
</ts>

And I expected the below code prints out three e on screen:

XMLInputFactory factory = XMLInputFactory.newInstance();
XMLStreamReader sr = factory.createXMLStreamReader(new FileReader("test.xml"));

while (sr.hasNext()) {
    int eventType = sr.next();

    if (eventType == XMLStreamReader.START_DOCUMENT) {
        continue;
    } else if (eventType == XMLStreamReader.END_ELEMENT) {
        System.out.println("e");
    } else if (eventType == XMLStreamReader.START_ELEMENT) {
        System.out.println("s");
    }
}

But it doesn’t work! Any ideas on how I can resolve the issue?

Note: I think it is related to self-closed-tags, for example: <myTag id="1" />

Answer 1

The code posted in your question produced the three e for me which is expected. I’m using JDK 1.6 on the Mac.

Demo

You may want to try running the following code to see which end element event you are missing:

import java.io.FileReader;
import javax.xml.stream.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        XMLInputFactory factory = XMLInputFactory.newInstance();
        XMLStreamReader sr = factory.createXMLStreamReader(new FileReader("test.xml"));
        System.out.println(sr.getClass());

        while (sr.hasNext()) {
            int eventType = sr.next();

            if (eventType == XMLStreamReader.START_DOCUMENT) {
                continue;
            } else if (eventType == XMLStreamReader.END_ELEMENT) {
                System.out.println("End Element:    " + sr.getLocalName());
            } else if (eventType == XMLStreamReader.START_ELEMENT) {
                System.out.println("Start Element:  " + sr.getLocalName());
            }
        }
    }

}

Output

Below is the output I get.

class com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl
Start Element:  ts
Start Element:  tr
Start Element:  node
End Element:    node
End Element:    tr
End Element:    ts
