[jdom-interest] Child number

[KhanhVinh Tran]

Thanks everyone for your advice.
My data is more complicated than what I put in the
previous sample.

Let's me make it clear.
ex:
<sample>        
  <child> 
    <name> A </name>
    <description> Andrew </description>
      <grandchild> 
        <name> A1 </name>
        <description> Andrew1 </description>     
      </grandchild>
      <grandchild> 
        <name> A2 </name>
        <description> Andrew2 </description>     
      </grandchild>
      ...
  </child>
  <child> 
    <name> B </name>
    <description> Brian </description>
      <grandchild> 
        <name> B1 </name>
        <description> Brian1 </description>     
      </grandchild>
      <grandchild> 
        <name> B2 </name>
        <description> Brian2 </description>     
      </grandchild>
      ...
  </child>
  ...
</sample>

It's complicated like above.  So if I know the child#,
the remove(child#) method will let me remove the whole
thing.  
For ex: allChildren.remove(1)
        This will remove child A and all grandchildren

Thanks!
