Your first example began with

list = "url1, irl2, url3, url4, url5"

but now your list looks like this:

list = "A,B,C,D"

The spaces are missing, so splitting on a comma followed by a space does 
not split anything in your second example. In your first example, it 
produces an array with 4 elements. In your second list it produces an 
array with one elemement: "A,B,C,D"

hth,
