<helloe>How r u <a> www.google.com</a>

From the above code the output which i got is 
&lt;helloe&gt;How r u <a> www.google.com</a>
&lt;hi&gt;How r u &lt;/hi&gt;&lt;et,-2&gt;&lt;&gt;

But the expected output is 
&lt;helloe&gt;How r u <a> www.google.com</a>
<hi>How r u </hi>&lt;et,-2&gt;&lt;&gt;

As '<hi>' as the '</hi>' I shouldn't replace it.
