I like the idea of using split() but decided to keep
most of my regex and incorporate split on the string.
So the string: 'Spurs 94, Suns 82' <-and there may or
may not be a space after the 2.
I decided to read up on split(), and then try to split
it.
This is what I came up with:
@teamscores = split(m#\s*\d*\,\s*#, $_);
This puts 'Spurs' in $teamscores[0] and 'Suns 82' in
$teamscores[1].
I think it has to do with the comma not being present
after 'Suns' so I modified the split() to look like
this:
@teamscores = split(m#\s*\d*\,*\s*#, $_);
that put 'p' in $teamscores[1]
so then I tried to make the comma and the space
optional as a group and did this:
@teamscores = split(m#\s*\d*(\,\s*)?#, $_);
and that gave me a use of uninitialized error with the
concatenation operator. I'm not sure what that's
about.
i tried one more change:
@teamscores = split(m#\s*\d*\,?\s?#, $_);
Since the comma wasn't present in the second number,
and I wasn't sure if the space was either. That
didn't give me what I expected. it gave me:
$teamscores[0] == S and $teamscores[1] == p
I'm not sure what's going wrong here. Can someone
tell me how I can split 'Spurs 94, Suns 82' into:
array[0] == 'Spurs' and array[1] == 'Suns'
Thanks. -stu
