Dealing with multiple enclosures in a feed

I am dealing with a feed that all of a sudden has multiple enclosures for some content and the code can’t deal with it. Here is the current code. How can I grab just a single enclosure? I actually don’t need all of them (they are the same), just one.

else if item.enclosure.Count() > 0
      print item.enclosure@url
      newStream = {
            url:	ValidStr(item.enclosure@url)
      }
      newItem.streams.Push(newStream)
      result.Push(newItem)
end if

Thanks!

Try: item.enclosure[0]@url
