	thanks for the quick response but I've already tried that. {% set var_html = "[special_tag]"%} {{ var_html|replace({"[special_tag]": "<p>new value</p>" }) }} result: <p>new value</p> expected: new value – karl2108 Apr 23 '14 at 8:58  You'll have to add another filter: raw: {{ var_html | replace(...) | raw }} – Crozin Apr 23 '14 at 9:18 Awesome! thanks! – karl2108 Apr 23 '14 at 23:03
