Three Variable Split

[jonnymp316]

Ok so what I want to do is to parse 1 line into 3 variables at 3 different points so here is what it looks like now:

my ($name, $value) = split /:/;

and here is what I want it to look like or do I guess:

my ($name, $value, $phone) = split /:/,/;

like I said its basically parsing one line at the colon) and the other at the comma(,) anyway if anyone could help that would be awesome.

Thanks,
-Jonny

split only allows one pattern match so you could use a group in your regular expression. Something like the following:

my ($name, $value, $phone) = split /[:,]/;

The caveat is that this is not positional. In other words if there is a , before a : then it will split on the comma first.

...or you could try

  $line =~ /^([^:]*):([^,]*),(.*)$/
    && my ($name, $value, $phone) = ( $1, $2, $3 );

which says grab every non-colon character from the top of the string into $1 (and thence into $name). Ignore the first colon, then grab every non-comma character up to the next comma into $2 (and thence into $value). Ignore the comma and put everything else into $3 (and thence into $phone).
