Another thing I have been playing with is XML using Apache Xerces. I plan to use XML files to store configuration information for programs. I also use several programs that use XML as a data file formats, and I need an easy way to parse various info from them. The following example will write out an XML file with a structure like so:
-Root(String1=Root_Node)
------Child(String2=child_node)
The code is below:
package xmlTest;
import java.io.File;
import java.io.FileOutputStream;
import javax.xml.parsers.*;
import org.w3c.dom.*;
import org.apache.xml.serialize.*;
public class XMLTestImpl {
/**
* @param args
*/
public static void main(String[] args) {
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
Element el;
DocumentBuilder db = null;
Document doc = null;
Element root = null;
XMLSerializer xmlSer;
OutputFormat out;
//Try to create the document builder
try
{
db = dbf.newDocumentBuilder();
doc = db.newDocument();
}
catch (Exception e)
{
e.printStackTrace();
System.exit(1);
}
//Creat the root class, called TEst
root = doc.createElement("Test");
doc.appendChild(root);
//Create child node to root
el = doc.createElement("child1");
root.appendChild(el);
//Set some arbitrary attribute
root.setAttribute("String1", "root_node");
el.setAttribute("String2", "child_node");
//Write out to file using the serializer
try
{
out = new OutputFormat(doc);
out.setIndenting(true);
xmlSer = new XMLSerializer(
new FileOutputStream(new File("/tmp/test.xml")), out);
xmlSer.serialize(doc);
}
catch(Exception e)
{
e.printStackTrace();
}
}
}

Hey John, just following up from the conference had a look at your site? Have you had a look at jaxb? Pretty cools stuff, given an XSD it will automagically create the classes to marshal/unmarshal between java and XML.

This mini-tutorial has been useful for me to start creating XML files. Thanks for this help. See you later.
P.S.: Do you know where I can find more examples?
