Hi: I am extracting some value from $complete_event asif ( $complete_event =~ /srcIp=(.+) srcPort=/ ) {

returned a valid value? "if($_)" seems to be giving
incorrect values. In the following statement, $srcIp
is being set to an old extracted value if there is no
valid value following srcIP in my $complete_string
instead of 0.
$complete_event =~ /srcIp=(.+) srcPort=/;
# true
}
else {
# false
}
Wags ;)
if($_) {$srcIp = $1;}
else {$srcIp = 0;}
Thanks
