 Thanks !

 I have a simple PHP function to minify all HTML elements in function.php
 You can see an example here :

 output#answer-6225706

 You can rewrite it more simple
 {{{#!php
 <?php
 ob_start(function ($buffer) {
     return preg_replace([
         '/\>[^\S ]+/s',  // strip whitespaces after tags, except space
         '/[^\S ]+\</s',  // strip whitespaces before tags, except space
         '/(\s)+/s'       // shorten multiple whitespace sequences
     ], ['>','<','\\1'], $buffer);
 });
 }}}
