Hey, I'm about to give this little application a bash at the minute but am struggling to grasp what needs to be achieved.

Basically I have an XML which looks like (for example):

<player>
<uid>1</uid>
<name>Bob</name>
<positionx> </positionx>
<positiony> </positiony>
</player>

<player>
<uid>1</uid>
<name>Bob</name>
<positionx> </positionx>
<positiony></positiony>
</player>

Now positionx and y are going to be the elements co-ords on the stage, I've currently got them appearing but I want to be able to effectively save their new x / y co-ords to the XML file without having to re-write the XML from scratch.

Effectively a logic of
-Drag movieclip(uid =1 (name=bob)) to a new position.
-press a button
-Flash sends the new X and Y location of the movie clip to a coldfusion script which then finds the <player> element with the uid of 1, and inserts the x location into the <positionx> part and the y location into <positiony>.

Does this make sense? I'm just currently researching the best method to do this as there are going to be multiple elements (wont just have to update uid=1/name=bob but also about another 10 movie clips on the stage).

Anyone offer any advice?
