XML parsing problem

I can’t correctly parse this XML in AS3
I’m using a Facebook API with AS3, so its fetching data from a MySQL and sending it back as a XML. I’m using the Photos_get method with Facebook API. It returns to Flash the XML documented below.

When you try to use the XML properties in AS3, its not correctly identifying nodes.
Usually just taking the result and assigning it as a XMLList does the trick, but I have realized that doesn’t work with complex XML structures.
Has anybody else had this issue? And knows how to fix it?
I have put a attachment of the file so you can see the issue for youself.

For example if you load the file in AS3, then for example only want to get the ‘src_big’ child values with a
trace(photos.src_big);
It will return nothing or just return the whole photo child if you try to retrieve it from a XMLList
