Remove HTML tags in String [closed]

Question

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?

Answer 1

Warning: This does not work for all cases and should not be used to process untrusted user input.

using System.Text.RegularExpressions; ... const string HTML_TAG_PATTERN = "<.*?>";  static string StripHTML (string inputString) {    return Regex.Replace       (inputString, HTML_TAG_PATTERN, string.Empty); }

You should use the HTML Agility Pack:

HtmlDocument doc = ... string text = doc.DocumentElement.InnerText;
