  <p><strong>String to identify:</strong></p>
  <p>S{test}fAct (the value between the brackets is alphanumeric)</p>
  <p><strong>Question</strong>
  How can I extract the string listed above with a Regex expression? I am a novice with regex and need help creating the correct expression.</p>
  <p>I have tried the following but am unable to only select the S{}fAct attribute:</p>
  <pre><code>\| S{.+}fAct \|
  </code></pre>
