Hi,
I have a question on pattern matching. Assume I have a line like this consisting of header field(via) and values(IPaddress) repeated like below
via: 192.168.6.100; via:192.168.6.101; via: 203.290.89.90; ......so on
I would like to know how many via: header field occur and to get each via header field value. I want to know how to loop through each via header field to extract the value by pattern matching expressions.
There are alternatives to using regexs:
#!/usr/bin/perl use strict; use warnings;
#chomp(my $header = <DATA>); #my @via = split /;\s*/, $header; #s/^via:\s*// for @via;
# -or-
#my @via = map { s/^via:\s*//; $_ }
# split /;\s*/, scalar <DATA>;print join "\n", @via;
__DATA__ via: 192.168.6.100; via:192.168.6.101; via: 203.290.89.90;
