Add attribute to a XML node at a specific position

Question

I have this XML :
var myNode:XML = <node attribute="123"/>
I know how to add an attribute to the node :
myNode.@otherAttribute = "abc";
But this adds the attribute to the end. What if I want to add it as the first attribute ? I would like to have :
<node otherAttribute="abc" attribute="123"/>
I know it is possible to add a child node to a specific position with insertChildAfter() or insertChildBefore() but I don't know if it's possible for an attribute.

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);
