Re: How do I find the Nth occurrence of a pattern?

[vroom]

Use the /g (global) to find all occurrences in a string. Place the matching statement within a while loop and count until you get to the wanted number.

$n=5;  #want the 5th occurrence of a group of 5 numbers
$count=0;
while(/(\d{5})/g){
   if(++$count==$n){
      print "The $n\th occurrence was $1\n";
   }
}
