Question:

How can I strip the HTML tags from a text string using regular expressions?


[Print this FAQ]

Answer: Have you ever wanted to strip all of the HTML tags from a string? There are many reasons you may want to do this. For example, if you provide a feature on your site where a user can have the contents of a Web page emailed to them, you may wish to strip all of the HTML tags from the particular article for those users whose email client does not support HTML-formatted email. (For more information on sending emails via ASP be sure to check out the Email FAQ Category.)

Stripping HTML tags is a breeze using regular expressions. Using the regular expression pattern:

<(.+?)>

will match all < and > tags that have one or more characters inbetween them. The non-greedy operator (?) ensures that the matches will occur where there are the fewest number of characters between the < and > tags. With this regular expression pattern, once we find all of the matches we need but use the Replace method to replace them with an empty string ("").

An article on 4Guys, Stripping HTML Tags using Regular Expressions, examines the complete code for this function. There's also a live demo that you can try out. Be sure to check out both the article and live demo!

Happy Programming!
