- * This class parses HTML code using pure JavaScript and executes various events for each item it finds. It will
- * always execute the events in the right order for tag soup code like <b><p></b></p>. It will also remove elements
- * and attributes that doesn't fit the schema if the validate setting is enabled.
- *
- * @example
- * var parser = new tinymce.html.SaxParser({
- * validate: true,
- *
- * comment: function(text) {
- * console.log('Comment:', text);
- * },
- *
- * cdata: function(text) {
- * console.log('CDATA:', text);
- * },
- *
- * text: function(text, raw) {
- * console.log('Text:', text, 'Raw:', raw);
- * },
- *
- * start: function(name, attrs, empty) {
- * console.log('Start:', name, attrs, empty);
- * },
- *
- * end: function(name) {
- * console.log('End:', name);
- * },
- *
- * pi: function(name, text) {
- * console.log('PI:', name, text);
- * },
- *
- * doctype: function(text) {
- * console.log('DocType:', text);
