我有一个像这样的html文本：

'<div class="a"><span>1</span><div>2</div></div>'

闭包库中是否有一个函数可以获取这样的字符串作为输入并返回 DOM 树以插入到文档中？

闭包库提供了从对象goog.dom.safeHtmlToNode(html)创建文档片段 ( Node)的功能goog.html.SafeHtml，可以使用goog.html.sanitizer.HtmlSanitizer如下所示创建。

例子

<!doctype html>
<html>
<head>
  <title>Closure Library Dom Test</title>
  <script src="https://cdn.rawgit.com/google/closure-library/master/closure/goog/base.js"></script>
  <script>
    goog.require('goog.dom');
    goog.require('goog.html.SafeHtml');
    goog.require('goog.html.sanitizer.HtmlSanitizer');
  </script>
</head>

<body>
<h1>Closure Library Dom Test</h1>

<div id="main">
</div>

<script>
  var sanitizer = new goog.html.sanitizer.HtmlSanitizer.Builder().build();
  var fragment = goog.dom.safeHtmlToNode(
      sanitizer.sanitize('<div class="a"><span>1</span><div>2</div></div>'));

  goog.dom.append(/** @type {!Node} */(document.querySelector('#main')),
      /** @type {!Node} */(fragment));
</script>

</body>
</html>
