Re^3: Nonrepeating characters in an RE

Well, in that case...

my @test = qw/xyzabcxxx xyzaabxxx xyzabbxxx xyzabaxxx/;

for (@test) {
    # only check for 'abc'
    say if not /([abc]).*?\1/;
}

Still quite simple, isn't it?

You can try to contact BernieC to find out how this substring is defined. Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply]
