need your help: extract Ids from elements

dear for all

i need to extract nodes from several comp like green elements in ordered way:

the idea is to extract nodes from begin 1 to end 1 and from begin 2 to end 2 separately

i used  [hm_getvalue comps id=$compid dataname=nodes.id] --> no ordred Ids 

any propositions?

thx
