Is there NO way to capture all the matches to a numerically quantified subexpression?
e.g.:
my $ham = "spam\tspam\tspam\t\tyam\tclam";
my @jam = ($ham =~ (m/^[^\t]*\t[^\t]*(?:\t([^\t]*)){3}\t[^\t]*$/));
print join("\n", '**', @jam, '**', '');
What I get is this:
**
yam
**
because each subsequent match to the group stomps on the previous one.
What I want is this:
**
spam
yam
**
I have searched and searched and searched for a simple answer to this, and I have come up empty.
Note that, for my purposes, the solution of pulling the inner set of three out as a string and splitting that string on tabs is NOT satisfactory: I want/need to grab all the desired fields in one go.
This should be
trivial, yet it seems to be
impossible.
