title: Regular expression to get last part of a string before a character
body: <p>I have this string on a single column of a single row on an oracle table:</p>
  <p>(test-1@gmail.com-<strong>1234567</strong>)</p>
  <p>(testAAAcccc@gmail.com-<strong>7654321</strong>)</p>
  <p>..</p>
  <p>Above it's a single big string.</p>
  <p>I need a regular expression to extract all the occurrences (could be 1 or more, 2 in above example) of the 7 numbers above, so the results should be:</p>
  <p><strong>1234567</strong></p>
  <p><strong>7654321</strong></p>
  <p>I'm trying to to that with various regular expression or oracle functions, I'm not able to get both the occurrences.</p>
  <p>Could you please help me?</p>
