Seems like a job for a higher-level code. Perl, python, awk, anything like that.
If the line can be very long you could expect unexpected problems (like storing too much data into a variable in shell or the line being truncated).
On the other side such trick could probably work as well: "for var in $(cat file); do .... done" or better - use "read".... you might need to play with the FS/IFS settings.
Anyway - I strongly suggest higher level language.

Documentation
Module Parsing
: sig end
The run-time library for parsers generated by ocamlyacc .
val symbol_start : unit -> int
symbol_start and Parsing.symbol_end are to be called in the action part of a grammar rule only. They return the offset of the string that
matches the left-hand side of the rule: symbol_start() returns the offset of the first character; symbol_end() returns the offset after the
last character. The first character in a file is at offset 0.
val symbol_end : unit -> int
See Parsing.symbol_start .
val rhs_start : int -> int
Same as Parsing.symbol_start and Parsing.symbol_end , but return the offset of the string matching the n th item on the right-hand side of
the rule, where n is the integer parameter to rhs_start and rhs_end . n is 1 for the leftmost item.
val rhs_end : int -> int
See Parsing.rhs_start .
val symbol_start_pos : unit -> Lexing.position
Same as symbol_start , but return a position instead of an offset.
val symbol_end_pos : unit -> Lexing.position
Same as symbol_end , but return a position instead of an offset.
val rhs_start_pos : int -> Lexing.position
Same as rhs_start , but return a position instead of an offset.
val rhs_end_pos : int -> Lexing.position
Same as rhs_end , but return a position instead of an offset.
val clear_parser : unit -> unit
Empty the parser stack. Call it just after a parsing function has returned, to remove all pointers from the parser stack to structures that
were built by semantic actions during parsing. This is optional, but lowers the memory requirements of the programs.
exception Parse_error
Raised when a parser encounters a syntax error. Can also be raised from the action part of a grammar rule, to initiate error recovery.
val set_trace : bool -> bool
Control debugging support for ocamlyacc -generated parsers. After Parsing.set_trace true , the pushdown automaton that executes the
parsers prints a trace of its actions (reading a token, shifting a state, reducing by a rule) on standard output. Parsing.set_trace false
turns this debugging trace off. The boolean returned is the previous state of the trace flag.
Since 3.11.0
