Ok, thanks, but dont think i explained my self very well
Basically, i have a properties list which stores a object with a name and a
value, which are both strings. name is the attribute name, so in ur example it
will be 'id' and the value will be '1'. so knowing that information i should be
able to filter the xml using them values.
var itemList : XMLList = <items>
<item id='1' quantity='2' type='fruit'>
<item id='2' quantity='5' type='veg'>
<item id='3' quantity='6' type='veg'>
<item id='4' quantity='7' type='fruit'>
</items>;
var propertyList : ArrayCollection = new ArrayCollection();
propertyList.addItem({name:'type' , value:'fruit'});
var filterList : XMLList = itemList.item;
for each(var property : Object in propertyList)
{
filterList = filterList.(attribute(property.name) == property.value);
}
//Output of filterList
<item id='1' quantity='2' type='fruit'>
<item id='4' quantity='7' type='fruit'>
So thats the basic idea but always get that error, looking in the API it
suggests it is possible to filter like that. Well hope this gives a better idea
of what the problem is. Thank You
