which of course explains why it would be able to match any
of the 'directory' names down the chain, but not quite why
it matches ONLY the last in the lot....
OYE! now I get it......
$doc =~ m!(.*)/(\w+)/!;
print "one is :$1: undt two is :$2:\n";
puts all of the stuff above 19463 into the (.*) {matchall} bit...
Whereas the scalar context walk of the form:
while($doc =~ m!/(\w+)!g) {
print "match is: $1 \n";
}
would hand out each in turn....
