just slice

depending on how the input file is created data packet a can be in an 
other position for every line.
figured out how to do it though

order=[a,b,e,d...]
for i in lines:
   i=i.split(" ")
     for j in order:
       if j = a:
	use function for processing data chunk a
       elseif j = b:
         use proper function for processing data type b
       ...

sorry

order of data chunks varies per file

Sorry for the amount of text below, I hope it clarifies
one line of space delimited input data:
