something like (not tested tho)

B4X:
Dim lines() As String
Dim data() As String
lines=regex.split(chr(13)&chr(10),yourresponsetext)
for x=0 to lines.lenght-1
 data=regex.split(",",lines(x))
 if data.lenght>0 then  'check if it is a parameters line to skip the first line
  mylat=data(3)
  mylong=data(4)
  'do your other stuff here
 end if
next

yourresponsetext in my code is the text you get back from your webdownload (if it is in the same format otherwise the code is useless)
