Parsing input file with DFDL page by page - dfdl

Question

I have a very simple row based document in which each row comprises a record. I want to have a DFDL that parses it into chunks that contains fixed number of rows(say, for example 3 records at each chunk).
Original File:
record1
record2
record3
record4
record5
record6
record7
After DFDL Parse:
1) [record1, record2, record3]
2) [record4, record5, record6]
3) [record7]
I am currently able to get all records at once with the following DFDL, but it creates a serious problem when the size of document gets bigger, that' s why i want to get these records page by page. Is it possible to do this? Does anyone have any idea how can this be done?
