Hi All,
I have one variable $feature which contains value as "feature level: 2".
Now i need to remove "feature level: " and need only 2 as a output.
I mean from the value "feature level: 2" i need only 2. Basically i need
to trucate/remove "feature level: ".
I tried in the following way
$feature = s/feature level: //g;
but the value of $feature is not 2.
Can anybody please help.
Hi Irfan
I suggest you shouldn't have 'feature level: ' in your string in the first
place! Where has it come from? If it's a line from a file, for instance, you
should write something like
while (<DATA>) {
if (/feature level:\s+(\d+)/) {
$feature_level = $1;
}
}
Try thinking of it this way round.
HTH,
Rob
