Re^2: Incremental replacement by regex

:-)

I was sure I tried single quotes. But it was the e modifier that I needed. Thanks

This was my effort in the end

my $t = "This example could be another example where the example is th
+e example I wanted\n";

my $count = 0;

while($t =~ /example\s/){
    my $example = "example_".++$count;
    $t =~ s/(example\s)/$example /;
    print $t;
}
print $t;

The 'g' in my example removes the need for the loop. One slightly pedantic comment on your code, you use `\s` and you should remember that it matches all whitespace, including a new-line. So, for example: `my $t = "This example could be another example where the example is th +e example I wanted, for example\n";` [download] removes the trailing "\n" and replaces it with a space, which is probably not what you want.

+e example I wanted, for example\n";
