title: Remove HTML tags in String
body: <p>How can I remove HTML tags from the following string? </p>
  
  <pre><code>&lt;P style="MARGIN: 0cm 0cm 10pt" class=MsoNormal&gt;&lt;SPAN style="LINE-HEIGHT: 115%; 
  FONT-FAMILY: 'Verdana','sans-serif'; COLOR: #333333; FONT-SIZE: 9pt"&gt;In an 
  email sent just three days before the Deepwater Horizon exploded, the onshore 
  &lt;SPAN style="mso-bidi-font-weight: bold"&gt;&lt;b&gt;BP&lt;/b&gt;&lt;/SPAN&gt; manager in charge of 
  the drilling rig warned his supervisor that last-minute procedural changes were 
  creating "chaos". April emails were given to government investigators by &lt;SPAN 
  style="mso-bidi-font-weight: bold"&gt;&lt;b&gt;BP&lt;/b&gt;&lt;/SPAN&gt; and reviewed by The Wall 
  Street Journal and are the most direct evidence yet that workers on the rig 
  were unhappy with the numerous changes, and had voiced their concerns to &lt;SPAN 
  style="mso-bidi-font-weight: bold"&gt;&lt;b&gt;BP&lt;/b&gt;&lt;/SPAN&gt;’s operations managers in 
  Houston. This raises further questions about whether &lt;SPAN 
  style="mso-bidi-font-weight: bold"&gt;&lt;b&gt;BP&lt;/b&gt;&lt;/SPAN&gt; managers properly 
  considered the consequences of changes they ordered on the rig, an issue 
  investigators say contributed to the disaster.&lt;/SPAN&gt;&lt;/p&gt;&lt;br/&gt;

  <p>I'm writing it to Asponse.PDF, but the HTML tags are shown in the PDF. How can I remove them?</p>
