title: Regular Expression to select all sentences Except one sentence with specific word
body: <p>I want to select all sentences which do not includes <strong>&quot;Bull &amp; Cat&quot;</strong> word.</p>
  <p><strong>This is a Dog. This is  Cat. This is a Bull. This is a Cow</strong></p>
  <pre><code>((?&lt;=^)|(?&lt;=\.))\s*(?![^.]*Bull).*?(?:\.|$)((?&lt;=$)|(?&lt;=\.))
  </code></pre>
  <p>This regex selects sentences except one that contain <strong>Bull</strong>, but I need to select all sentences other than contains <strong>Bull &amp; Cat</strong>.</p>
  <p>Edit the above regex. So, i can select all sentences except those who contains Bull &amp; Cat.</p>
