[flexcoders] looping xml structure

[Jason B]

I've so far got an xmlcollection

using this code shows the xml code

for each (var xmlitems in xmlcollection_data)
                         {
                                trace(xmlitems);
                         }

but i'd like to know how to loop the collection and search for strings
etc.. any link to an example would be fine too, my googling for 
"for loop xmllistcollection"
"loop xmllistcollection"
and many others turned sour
