Simple xml parse

Question

hi, i am using the next code:
dibujos_XML = new XML(_loader.data);
            var _dibujos:XMLList = dibujos_XML.children();
            var _dibujo_id:Number;
            for each (var _dibujo:XML in _dibujos) {
                if (_dibujo.localName()!="dibujo")
                    throw new Error("nodo XML no es un dibujo");
                if (_dibujo.hasOwnProperty("id")==false)
                    throw new Error("nodo XML no contiene identificación");
                _dibujo_id = Number(_dibujo.id);
                trace(_dibujo_id)//.toXMLString());
on the next file:
<p>
<dibujo id="1">a</dibujo>
<dibujo id="2">as</dibujo>
<dibujo id="34">asd</dibujo>
<dibujo id="54">123</dibujo>
</p>
if it was doing what i think it should do, it should take each 'dibujo' node, check that it was a 'dibujo' (this part works ok so far), then check that each 'dibujo' had an id property. this part is failing. it seems to be throwing exception with the next sentence:
if (_dibujo.hasOwnProperty("id")==false)
                    throw new Error("nodo XML no contiene  identificación");
if i comment this sentence, there is no error but the trace prints all 0s. if i understood, it should check that the current node stored in '_dibujo' has a property called 'id', which all have, and set the value of that property to some other var, which does not seem to be doing. any pointers?
tnx

Answer 1

id is an attribute, so you need to use this:
_dibujo.hasOwnProperty("@id")
