So which output do you want for that input sample? Do you want to 
generate two documents, one containing the groups for the processing 
instructions, the other copying the input, or do you want to mix the 
input with the groups? In the last case, how exactly?

I am sure we can adapt the code once we know exactly which result you 
want, but currently I am not sure how that result is supposed to look like.
