Select XML Node by a specific attribute value

Question

I am newbie for LifeCyle.
This might be an easy question, but it really got me here.
I am trying bind xml data into a Drop-Down List. The databinding is working fine, but I would like to have more specific node selected from the xml file by using a attribute value.
for example Code in AS 3.0
root.node.(@id=="1").subNode
How could i do the same thing in LifeCycle Designer 8.0
Thank you in advance!!!

there's no native method for this, maybe you should create some functions for this. just like
private function setAttribute(node:XML, name:String, value:String, index:int = -1):void
    var attrs:XMLList = node.attributes().copy(),
        l:int = attrs.length();
    if(index == -1 || index > l - 1)
        node.@[name] = value;
    else
        delete node.@*;
        var idx:int = 0;
        for (var i:int = 0; i < l + 1; i++)
            if(i == index)
                node.@[name] = value;
            else
                var attr:XML = attrs[idx];
                node.@[attr.name()] = attr.toString();
                idx++;
and use it like this:
setAttribute(myNode, "otherAttribute", "abc", 0);
