title: Change delimiter of grep command
body: <p>I am using <em>grep</em> to detect <code>&lt;a href="xxxx"&gt; something here &lt;/a&gt;</code><br>
  This is not working when the link is split on two lines in the input. I want to grep to check till it detects a <code>&lt;/a&gt;</code> but right now it only is taking the input into grep till it detects a new line.</p>
  
  <p>So if input is like <code>&lt;a href="xxxx"&gt; something here &lt;/a&gt;</code> it works,  but if input is like</p>
  
  <pre><code>&lt;a href="xxxx"&gt;
  
  something here /a&gt;    
  </code></pre>
  
  <p>, then it doesn't.
  Any solutions?</p>
