How to add nodes in xml file at specific position?

programming flash
1

Lets say i have the following xml file which i load in Flash:


<example>
    <items title="something>
      <img id="image"/>
      <audio id="audio" />
      <text id="text"/>
    </items>
</example>

And i would like to add the following line:


<video id="video">

after the node so that input xml looks like this:


<example>
    <items title="something>
      <img id="image"/>
      <audio id="audio"/>
      <video id="video"/>
      <text id="text"/>
    </items>
</example>

I’ve done the loading part but can’t figure it out how to add new node at specific position. Can someone please show me how to do that ?

thanks a lot
