The three find method calls in the for loop are searching from the
document root (the "soup" variable), not from the item you're
currently iterating at.  Try changing these to calls of item.find. And
note that calling one of the results "item" will replace the loop
variable.  That won't affect the iteration, but it's bad practice to
refer to two different things by the same local name.
