Replacing a part of text inside a td
<p>I have a <code>td</code> with this format:</p>

<pre><code>&lt;td&gt;
    Business Owner - Delivery Director &lt;br&gt;
    &lt;a href="mailto:me@business.com"&gt;me@business.com&lt;/a&gt;
&lt;/td&gt;
</code></pre>

<p>How can I only replace the text <code>"Business Owner - Delivery Director"</code> with something else?  </p>

<p>Using this.text() fetches <code>Business Owner - Delivery Director</code> and <code>me@business.com</code>, but I  want only
<code>Business Owner - Delivery Director.</code></p>
