Break down a regex expression into single regex?

zen0n has asked for the wisdom of the Perl Monks concerning the following question:

I am looking for a way to "break down" a regex expression into individual regex strings. for example

my $regex = "(^[1-3]|^yyy|^zzz)";
my @regexs = convert($regex);

would create a list like
$regexs[0] = "^1"
$regexs[1] = "^2"
$regexs[2] = "^3"
$regexs[0] = "^yyy"
$regexs[0] = "^zzz"
[download]

or some other equiv functionality :) Thanks

Your question has implications very like this recent thread: Reverse regexp a regexp? However, YAPE::Regex::Explain may do something like what you want. HTH, planetscape	[reply]

Your pseudo-coded problem statement makes very little sense. read `perldoc perlretut` or any number of other documents re regexen. Change the capturing parens and perhaps add `/g`. Come back and show us what you've tried along with an explanation of how it fails, if that's the case	[reply] [d/l] [select]
