    Post How To Retain Entity Reference Character While Reading XML

    I have an xml file input.xml as below:
    <?xml version='1.0' encoding='UTF-8'?>
    <parameter name="&quot;name&quot;">

    And I use dom4j library to parse the xml file to add email address postfix "@sa.com" to useranme element value:
    import org.dom4j.*;
    import org.dom4j.io.*;
    import java.io.*;
    public class Main {
    	public static void main(String[] args) throws Exception {
    	    SAXReader reader = new SAXReader();
    	    InputStream in = new FileInputStream("input.xml");
    	    Document doc = reader.read(in);
    	    Element element = (Element) doc.selectSingleNode("/parameter/username");
    	    element.setText(element.getText() + "@sa.com");
    	   StringWriter writer = new StringWriter();
    	   System.out.println("Converted Xml is:\n" + writer.toString());

    After running the code, I get below result:
    Converted Xml is:
    <?xml version="1.0" encoding="UTF-8"?>
    <parameter name="&quot;name&quot;">

    From the result, you can see the summary element value changes from
    But the name attribute value which contains entity reference character doesn't change.

    Why is it working like this? If I want to retain the original summary element value <summary>&quot;summary&quot;</summary>, how should I achieve that?

    Hello leon850515.

    Welcome to the Java Programming Forums.

    The only difference I can see between

    <parameter name="&quot;name&quot;">



    Is that the first one is in quotes. I'm not sure if this makes a difference?!

    Try changing




    and see what happens... This is just a test
