The tree may be manipulated using the DOMUtils library. + +##Usage +```javascript +var handler = new DomHandler([ <func> callback(err, dom), ] [ <obj> options ]); +// var parser = new Parser(handler[, options]); +``` + +##Example +```javascript +var htmlparser = require("htmlparser2"); +var rawHtml = "Xyz <script language= javascript>var foo = '<<bar>>';< / script><!--<!-- Waah! -- -->"; +var handler = new htmlparser.DomHandler(function (error, dom) { + if (error) + [...do something for errors...] + else + [...parsing done, do something...] + console.log(dom); +}); +var parser = new htmlparser.Parser(handler); +parser.write(rawHtml); +parser.done(); +``` + +Output: + +```javascript +[{ + data: 'Xyz ', + type: 'text' +}, { + type: 'script', + name: 'script', + attribs: { + language: 'javascript' + }, + children: [{ + data: 'var foo = \'<bar>\';<', + type: 'text' + }] +}, { + data: '<!-- Waah! -- ', + type: 'comment' +}] +``` + +##Option: ignoreWhitespace +Indicates whether the DOM should exclude text nodes that consists solely of whitespace.
