how to store these values into the xml

[kaleeswaran]

hi!
i was attend one interview..almo st i completed all my interview rounds.
now they given a task for final thing.
This is my task:
The Project should only consists of *.html,*.css,*. js,*.xml.
so ,i decided to store my data into xml file ...and i am going to display the data's into the html page.
now my concept is this:
i have contact list inside that i have Friends,Family, Workers.
Each list i have First Name and Last Name.
so these data's are i have to display in Tree Structure Format into the html file..
when the user Clicks the Friends ,Family,Workers folder Should close and hides contact within it.
for eg:
when the user clicks the Friends Folder the name List should display like this:

-contact
-Friends
-Jean-Louis Durant
-Rene Norega
+Family
+Work

so ,
when the User Clicks Jean-Louis Durant then Two Text Fields are there In My HTML Page so First Name and Last Name display respectively.

like first Name:Jean-Louis
Last Name:Durant.
That's it.
Hope you all understand my situtation.
how to store into the xml file...means what is the structure.pleas e give me some solution.
Thank you,
Kaleeswaran

the XML structure you want is what you already descibed:
1. list
2. contact
3.a Friends
3.b Family
3.c Workers
4.a First Name
4.b Last Name

or put into XML:

<list>
  <contact>
    <friends>
      <person>
        <firstname>
        <lastname>
      </person>
...
    </friends>
    <family>
...
    </family>
    <workers>
...
    </workers>
  </contact>
...
</list>
