Yet another parsing question

[Gallagher, Tim F \(NE\)]

Lets say that I have a list of data that have a few things in common, ie
 
this is a 1 test to see 2 what is happening 3 to the state of the 4
country
all work 1 and no 2 play makes 3 jack a dull boy 4
how 1 much wood 2 could a wood 3 chuck 4 chuck
 
so I want to grab all data between 1 - 2 and 3 - 4  2 different
variables, can this be done?
 
Thanks.
