Unfortunately, the range operator doesn't work in a regex...though it would
be nice if it did (of course I could be wrong)... I would try something
like:
while( <IN> ) {
while( /,\d+,/g ) {
if( in_range( $1 ) ) {
# do whatever
last; #get out of the while loop
}
}
}
The first while loop will loop through the lines of the file as you already
know. The second while loop will loop through the numbers that are
surrounded by commas. If one of them is in_range (I leave it to the reader
to devise an appropriate in_range function), then it will do the appropriate
actions and break out of processing the current regex. It will then
continue on to the next line.
