Need help in coding

[Shanthi Priya]

Hi ranchers,
I am novice to sax and dom parsers. I have to convert a simple xml file to java object and then convert the java object back to xml for ex:
i want to convert simple.xml

<addressbook>
<person>
<fistname>james</firstname>
<lastname>bond</lastname>
<address>usa</address>
</person>
<person>
<fistname>micheal</firstname>
<lastname>jannet</lastname>
<address>usa</address>
</person>
</addressbook>

parse this xml using sax or dom parser and convert to java object(sample.java) and then convert the object to output.xml

please help me!!!

Thanks in advance,
Priya.

You could parse the XML into a DOM tree and then do something like this:

Document doc = parseXmlToDomDocument(...);
NodeList personElements = doc.getElementsByTagName("person");
for (int i = 0; i < personElements.getLength(); i++) {
    Element personElement = (Element) personElements.item(i);
    processPersonElement(personElement);
}

Now, in the "processPersonElement" method, you can create an instance of foo.bar.Person, populate it's fields, put it into a collection of some sort, etc.
