in thread grep question using multiple lines

My solution with the while loop works with many emails on the same line. In fact doing so we consider the text as a whole totally ignoring newlines.

The idea of /g flag within a while is each match will start where the previous one has stopped and the loop stops when there is no more successful match.

The special variable @- is an array with the match start and end positions respectivly as $-[0] and $-[1] it might help to see what the loop does,

while ($txt =~ /constant=(\w+@\w+\.\w+)/g) {
  print "==> match starts at $-[0]!!!\n";
  print "$1\n";
}

    By my reading, the OP wants to know how to use the PCRE capability of BBEdit (or TextWrangler) to accomplish this task. While BBEdit has a mechanism for invoking scripts, I do not think that was what the OP was asking about. There are many merits to your answer, but it is not something that can be implemented directly in BBEdit.
