  </code></pre>
  <p>Now I want to get sub strings from it like this :</p>
  <pre><code>1. Error import KeyPair: InvalidKeyPair.Duplicate: The keypair 'avtx-ctrl-key' already exists.status code: 400,
  2. Error: Error creating IAM policy my-assume-role-policy: EntityAlreadyExists: A policy called my-assume-role-policy already exists. Duplicate names are not allowed.\n\tstatus code: 409, request id: 643d1d64-4b27-43db-be11-5585410c31c2
  </code></pre>
  <p>and so on.</p>
  <p><strong>Explanation</strong> :  Evvery sub string will be extracted which start from Word <strong>Error</strong> and end where  <code>request id</code> of that error is show till then. So same way every string can have 4,5 sub strings.</p>
