XOM API for Processing XML with Java

[Arjan Huijzer <huijzer AT gmail.com>]

I do not know if this is what you're looking for, but I have included a 
simplified version of some code I wrote a while ago.
Basically I subclassed nu.xom.Element so I could add some convenience 
methods.

Hope this helps,
Arjan Huijzer

=================================
book.xml
=================================
<?xml version="1.0" encoding="utf-8"?>
<book>
<chapter>
<title>Chapter 1</title>
</chapter>
<chapter>
<title>Chapter 2</title>
</chapter>
<chapter>
<title>Chapter 3</title>
</chapter>
<chapter>
<title>Chapter 4</title>
</chapter>
<chapter>
<title>Chapter 5</title>
</chapter> 
</book>


=================================
Chapter.java
=================================
package org.xamples.xomtest;

import nu.xom.Element;

public class Chapter extends Element {

String title;

public Chapter(Element chapterElement) {
super(chapterElement);
}

public String getTitle() {
if (title == null) {
Element titleElement = this.getFirstChildElement("title");
title = titleElement.getValue();
}
return title;
}

}

=================================
Processor.java
=================================
package org.xamples.xomtest;

import java.io.IOException;

import nu.xom.Builder;
import nu.xom.Document;
import nu.xom.Elements;
import nu.xom.ParsingException;

public class Processor {

public static void main(String[] args) {

Document doc = null;

try {
Builder parser = new Builder();
doc = parser.build("book.xml");
} catch (ParsingException ex) {
ex.printStackTrace();
} catch (IOException ex) {
ex.printStackTrace();
}

Elements chapterElements = doc.getRootElement().getChildElements("chapter");
for (int i = 0; i < chapterElements.size(); i++) {
Chapter ch = new Chapter(chapterElements.get(i));
System.out.println( ch.getTitle() );
}

}
}
