Displaying malformed html with twig

Assume we have a string

$mystring = "<b> Hello"

How can I display this string using twig while preventing leaking html tags? Or in other word how can I make twig to close tags automatically if they are still open?

I guess {{ mystring | raw }} just prints raw text without verifying / purifying.

Solution

  • sw_sanitize does this already.

    {{ '<b> hello' | sw_sanitize }}

    Produces:

    <b> hello</b

    Internally \HTMLPurifier::purify is used, which

    Filters an HTML snippet/document to be XSS-free and standards-compliant.
