Regular Expression Help

[triggerthat]

How can I evaluate in a text field if someone types in DD/MM/YYYY OR a string?

I've got the following expression for the date:

^(0?[1-9]|[12][0-9]|3[01])[ \/.-](0?[1-9]|1[012])[ \/.-](19|20)\d\d$

How can I change it to also include a particular string value (say test)?

Can you explain that a bit better I'm struggling to understand what you mean?

I want an expression that evaluates the following by entering either: 11/12/2008 or Hello

Well in perl this would be

use strict;

while(my $input = <STDIN>){

if($input =~ /([0-9]{2}\/[0-9]{2}\/[0-9]{4})|(hello)/){
print "Match \n";
}else{
print "No Match\n";
}

}

The cheat sheet and the testing page have come in really handy.
