Hi all,
this is a real beginner question, but I don't seem to find a good solution:
I have a single line of whitespace separated values, e.g.:
50 100
150 200 300 50
Now I want to split these values into an array using split, like:
my @array = split(/\s+/,$line);
but, unfortunately, the first value in the array is now an empty value.
I can of course shift this value from the array, but I believe there
must be a more elegant solution to this.
So I thought about using a positive look-behind assertion in which I
look for any number preceded by a whitespace, e.g. something like:
my @array = split(/\d+(?<=\s+)/,$line);
but perl will only accept fixed-width values for look-behind assertions.
Anyone any ideas?
cheers,
Bram
