Problem

How can I remove HTML tags from the following string? ``` <P style="MARGIN: 0cm 0cm 10pt" class=MsoNormal><SPAN style="LINE-HEIGHT: 115%; FONT-FAMILY: 'Verdana','sans-serif'; COLOR: #333333; FONT-SIZE: 9pt">In an email sent just three days before the Deepwater Horizon exploded, the onshore <SPAN style="mso-bidi-font-weight: bold"><b>BP</b></SPAN> 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 <SPAN style="mso-bidi-font-weight: bold"><b>BP</b></SPAN> 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 <SPAN style="mso-bidi-font-weight: bold"><b>BP</b></SPAN>’s operations managers in Houston. This raises further questions about whether <SPAN style="mso-bidi-font-weight: bold"><b>BP</b></SPAN> managers properly considered the consequences of changes they ordered on the rig, an issue investigators say contributed to the disaster.</SPAN></p><br/> ``` I'm writing it to Asponse.PDF, but the HTML tags are shown in the PDF. How can I remove them?
