writing xml using java

[webgenie]

i have a pre generated xml document and need to write into it using java. for example, the xml file i have is

<address-book>
<person name = "abc" number = "123">
</person>
</address-book>

How do I add more persons in the above schema using Java? Is there an API which can help in doing this?

Also, in case I want to express one of the values as null like,
<person name = null >

How is this done? using quotations and null within just initialises the name as "null".

Please help.

Thank you.

This really depends on the code of the app that receives your xml. Without knowledge of that we cannot say.
