Try using /filter to find the matches in the txt file, then /play to send them to the channel.
Code:
on *:text:!V *:#:{
  filter -ffg file.txt tmpresult.txt / $+ $replace($2-,$chr(32),|) $+ /i
  .play # tmpresult.txt
  .remove tmpresult.txt
}
The above searches in "file.txt" so change that part to whatever your file is named.

/help /filter
/help /play
