If you know they will always be around -, then you might be able to do
something like:
while( $line =~ /(\d\d?-\d\d?)|(T+)/g ) {
push @snow, ($1 || $2); #T will be $2, not $1
}
Also, I'm not sure why you had all of the [], they make a character class
which is probably not what you want.

Subject: A regex question
Hello,
I have a line of text like so:
SNOW 12HR 00-00 00-00 1- 2
I've written a regex to parse these lines and grab the values in between the
hyphens like so:
while ($line =~ /([\d]{1,2})|([T+])/g) {
push @snow, $1;
}
On occasion instead of a numerical snowfall amount "T" is used to indicate a
trace.
In the above line in question; I will get all the numbers however I also
capture the "12" in "SNOW 12HR" which I don't want. I've modified the
above regex to be like so;
while ($line =~/([\d]{1,2})\W{1,2}|([T+])/g) {....
I eliminate the "12" in "12HR", however I also lose the last numerical
forecast value (in the above line the final "2").
I am guessing my problem is likely with the newline at the end of the final
digit however I've not been able to map a solution using regexes to this.
Incidentally I've been able to solve the problem by using the first regex
and eliminating the first "12" via a for loop and counting from $snow[1],
not $snow[0].
Anyone have insights as to how the above regex could be made to work?
Thanks,
Don
