Clear HTML tags using regular expressions (RegEx)

In some cases, users are prohibited from submitting HTML-containing content due to security considerations. However, client verification and restrictions are always untrusted.

At this time, we need to securely process the submitted content and remove all HTML tags.

Alternatively, We need to extract part of some mixed content as the abstract. At this time, we also need to clear the HTML Tag.

 

I. C # Method

System. Text. regularexpressions. RegEx Reg = new system. Text. regularexpressions. RegEx ("</? [^>] +> ", System. Text. regularexpressions. regexoptions. ignorecase );

String cleansed result = reg. Replace ("content to be cleansed ","");

Ii. Javascript

VaR striptagsre =/<\/? [^>] +>/GI;

Striptags = function (v ){

Return! V? V: string (V). Replace (striptagsre ,"");

}

// Usage

Result of VaR cleanup = striptags ("content to be cleansed ");
