How to add a node to XML with XMLBeans XmlObject

My goal is to take an XML string and parse it with XMLBeans XmlObject and add a few child nodes.

Here's an example document (xmlString),

<?xml version="1.0"?>
<rootNode>
 <person>
  <emailAddress>[email protected]</emailAddress>
 </person>
</rootNode>

Here's the way I'd like the XML document to be after adding some nodes,

<?xml version="1.0"?>
<rootNode>
 <person>
  <emailAddress>[email protected]</emailAddress>
  <phoneNumbers>
   <home>555-555-5555</home>
   <work>555-555-5555</work>
  <phoneNumbers>
 </person>
</rootNode>

Basically, just adding the <phoneNumbers/> node with two child nodes <home/> and <work/>.

This is as far as I've gotten,

XmlObject xml = XmlObject.Factory.parse(xmlString);

Thank you

Method getDomNode() gives you access to the underlying W3C DOM Node. Then you can append childs using W3C Document interface.

XMLBeans seems like a hassle, here's a solution using XOM:

import nu.xom.*;

Builder = new Builder();
Document doc = builder.build(new java.io.StringBufferInputStream(inputXml));
Nodes nodes = doc.query("person");
Element homePhone = new Element("home");
homePhone.addChild(new Text("555-555-5555"));
Element workPhone = new Element("work");
workPhone.addChild(new Text("555-555-5555"));
Element phoneNumbers = new Element("phoneNumbers");
phoneNumbers.addChild(homePhone);
phoneNumbers.addChild(workPhone);
nodes[0].addChild(phoneNumbers);
System.out.println(doc.toXML()); // should print modified xml

Here is an example of using the XmlCursor to insert new elements. You can also get a DOM Node for an XmlObject and using those APIs.

import org.apache.xmlbeans.*;

/**
 * Adding nodes to xml using XmlCursor.
 * @see http://xmlbeans.apache.org/docs/2.4.0/guide/conNavigatingXMLwithCursors.html
 * @see http://xmlbeans.apache.org/docs/2.4.0/reference/org/apache/xmlbeans/XmlCursor.html
 */
public class AddNodes
{
    public static final String xml =
    "<rootNode>\n" +
    "  <person>\n" +
    "    <emailAddress>[email protected]</emailAddress>\n" +
    "  </person>\n" +
    "</rootNode>\n";

    public static XmlOptions saveOptions = new XmlOptions().setSavePrettyPrint().setSavePrettyPrintIndent(2);

    public static void main(String[] args) throws XmlException
    {
        XmlObject xobj = XmlObject.Factory.parse(xml);
        XmlCursor cur = null;
        try
        {
            cur = xobj.newCursor();
            // We could use the convenient xobj.selectPath() or cur.selectPath()
            // to position the cursor on the <person> element, but let's use the
            // cursor's toChild() instead.
            cur.toChild("rootNode");
            cur.toChild("person");
            // Move to </person> end element.
            cur.toEndToken();
            // Start a new <phoneNumbers> element
            cur.beginElement("phoneNumbers");
            // Start a new <work> element
            cur.beginElement("work");
            cur.insertChars("555-555-5555");
            // Move past the </work> end element
            cur.toNextToken();
            // Or insert a new element the easy way in one step...
            cur.insertElementWithText("home", "555-555-5555");
        }
        finally
        {
            if (cur != null) cur.dispose();
        }

        System.out.println(xobj.xmlText(saveOptions));
    }

}

It may be a little difficult to manipulate the objects using just the XmlObject interface. Have you considered generating the XMLBEANS java objects from this xml?

If you don't have XSD for this schema you can generate it using XMLSPY or some such tools.

If you just want XML manipulation (i.e, adding nodes) you could try some other APIs like jdom or xstream or some such thing.
