Question

我有一个看起来像这样的html字符串：

<body>
I am a text that needs to be wrapped in a div!
<div class=...>
  ...
</div>
...
I am more text that needs to be wrapped in a div!
...
</body>

因此，我需要将悬挂的html文本包装在自己的div中，或将整个主体（文本和其他div）包装在顶级div中。有没有办法用JSoup做到这一点？非常感谢你！

如果要将全身包裹在div中，请尝试以下操作：

    Element body = doc.select("body").first();
    Element div = new Element("div");
    div.html(body.html());
    body.html(div.outerHtml());

结果：

<body>
  <div>
    I am a text that needs to be wrapped in a div! 
   <div class="...">
     ... 
   </div> ... I am more text that needs to be wrapped in a div! ... 
  </div>
 </body>

如果要将每个文本包装在单独的div中，请尝试以下操作：

    Element body = doc.select("body").first();
    Element newBody = new Element("body");

    for (Node n : body.childNodes()) {
        if (n instanceof Element && "div".equals(((Element) n).tagName())) {
            newBody.append(n.outerHtml());
        } else {
            Element div = new Element("div");
            div.html(n.outerHtml());
            newBody.append(div.outerHtml());
        }
    }
    body.replaceWith(newBody);

<body>
  <div>
    I am a text that needs to be wrapped in a div! 
  </div>
  <div class="...">
    ... 
  </div>
  <div>
    ... I am more text that needs to be wrapped in a div! ... 
  </div>
 </body>

Jsoup：将属于body的文本包装在div中？
