Dynamic HTTPService request AS3

Question

I'm doing a mashup in Flex right now using Yahoo Maps. One of
the functions allows users to create their own routes.
Here's the problem. I need a dynamic httpService request
because I never know beforehand how many markers a route holds.
Here's my code:
[Bindable]
private var rssFeed:String;
private function opslaanRoute(event:Event):void
if(this.tekstInputVenster.text!="")
if(markerLijst.length>0)
rssFeed = "<route>";
rssFeed +=
"<routebeschrijving>"+this.tekstInputVenster.text+"</routebeschrijving>";
var lengte:Number = markerLijst.length;
for(var d:Number=0;d<lengte;d++)
rssFeed +="<marker>";
rssFeed +=
"<latlon"+d+">"+markerLijst[d][0]+"</latlon"+d+">";
rssFeed +=
"<indexMarker"+d+">"+markerLijst[d][1]+"</indexMarker"+d+">";
rssFeed +=
"<titel"+d+">"+markerLijst[d][2]+"</titel"+d+">";
rssFeed +=
"<beschrijving"+d+">"+markerLijst[d][3]+"</beschrijving"+d+">";
rssFeed +="</marker>";
rssFeed += "<aantal>"+indexMarkers+"</aantal>";
rssFeed += "<userid>"+_loginid+"</userid>";
rssFeed += "</route>";
opslaanR.send();
else
Alert.show("U moet markers toevoegen om op te slaan!");
else
Alert.show("U moet een routebeschrijving toevoegen om op te
slaan!");
The httpservice looks like this:
<mx:HTTPService
id="opslaanR"
url="url"
useProxy="false"
method="POST"
resultFormat="e4x"
result="opslaanSucces(event)"
showBusyCursor="true"
>
<mx:request>
{rssFeed}
</mx:request>
</mx:HTTPService>
The "aantal" tag is the number of markers a route holds.
Basically I want to loop the $_POST variables in php using "aantal"
so I can add them to my database. The PHP works flawlessly but it
never gets the httpservice values.
Please help.

Answer 1

well you understood me, I want an alternative to the script what I put in AS2,
but I think. of the script as you sent me centenary assume that I have in the library button menu0 menu1 .....
But I have only one menu button.
because I tried it and it did not work.
var ClassRef: Class = Class (getDefinitionByName ("menu" + i));
I will be happy if later you look again
