How to retrieve all Variables from a Twig Template?

Question

Is it possible to retrieve all variables inside a Twig template with PHP?

Example someTemplate.twig.php:

Hello {{ name }}, 
your new email is {{ ema

If you need all Twig elements inside of a text, just use:

preg_match_all('/\{\%\s*(.*)\s*\%\}|\{\{(?!%)\s*((?:[^\s])*)\s*(?

I had a issue where the WSIWYG editor placed HTML tags inside of Twig variables. I filter them with:

public function cleanHTML($text)
{
    preg_match_all('/\{\%\s*(.*)\s*\%\}|\{\{(?!%)\s*((?:[^\s])*)\s*(?

UPDATE

Use this expression to find all {{ }} and {% %}

preg_match_all('/\{\%\s*([^\%\}]*)\s*\%\}|\{\{\s*([^\}\}]*)\s*\}\}/i', $text, $matches);
