Need Help??

in reply to regex: only want [a-zA-Z] and comma chars in a string

Hi heezey,

Why not try without regex?

print "yes" if not tr/a-zA-Z,//c and not ( str( $_, ',', 0) or str $_,
+ ',' ,-1);

Did not check it but should work.

Cheers,

After some self-flaggalation:

for (qw/ ,asd asd:asd asd, asd,asd asd,,asd/){
 my $test = $_;
 print "$test: ";
 print "yes" unless $test=~tr/a-zA-Z,//c or index( $test, ',') == 0 or
+ index( $test, ',') == -1 + length( $test) or index( $test, ',,') > 0
+;
 print "\n";
 }

My perl clearly is rusty, and I even don't know anymore in which language str is valid ;).

However, still possible without regexes {grin}.

bzzt! Why post guesses when 10 seconds would have allowed you to check? The strings are not allowed to have consecutive commas, and `str($_,',',0)` isn't even a valid Perl function.	[reply] [d/l]
