No, that's not correct.
Besides the typos and the fact that you probably don't really want to eliminate whitespace or put non-date elements into your @dates array, your regex has some problems.
Working from the example you give, this might be a little closer to what you want:
my @dates;
while (<FILE>) {
while (m!(\d{2,4}[-/]\d{2}[-/]\d{2,4}|\w+\s+\d+\s+\d+)!g) {
push @dates, "<date>$1</date>"
}
}
That could match a whole bunch of other stuff too though... If you can better explain what you need someone will almost surely give you something better than that.
