  32. * @preserve_comments - Bool; [optional];
  33. * Set this flag to true to prevent removing comments from @text ( minxml and mincss functions only. )

  35. * Examples:
  36. * vkbeautify.xml(text); // pretty print XML
  37. * vkbeautify.json(text, 4 ); // pretty print JSON
  38. * vkbeautify.css(text, '. . . .'); // pretty print CSS
  39. * vkbeautify.sql(text, '----'); // pretty print SQL
  40. *
  41. * vkbeautify.xmlmin(text, true);// minify XML, preserve comments
  42. * vkbeautify.jsonmin(text);// minify JSON
  43. * vkbeautify.cssmin(text);// minify CSS, remove comments ( default )
  44. * vkbeautify.sqlmin(text);// minify SQL
