Thanks, that's an interesting approach. I find the logic still rather complex, though, and I think if I were going in this direction I'd separate it out a bit differently:
while (pos($tag) < length($tag)) {
if (m{ \G (\w+) \s* = }gcx) {
push @args [ $1 ];
} elsif (m{ \G (\w+) (?= \s* | \z ) \s* }gcx) {
push @args, $1;
} elsif (m{ \G (['"]) ( \\. | [^\\] )*? \1 \s* }gcx) {
(my $quoted = $2) =~ s/\\(.)/$1/g;
push @args, $quoted;
} else {
die "parsing error\n";
}
}
for (my $i = 0; $i < @args; ++$i) {
$args[$i][1] = splice(@args, $i + 1, 1) if ref $args[$_];
}
