Question

我正在使用JSOUP库来解析html.But我最终在我的DOM中添加了编码＆lt;＆gt;（＆amp; lt和＆amp; gt）的额外结束标记.Hence我使用了String utils库摆脱那些编码的东西。虽然我仍然有重复的结束标签，但他们没有编码。所以我的初始html是

<!DOCTYPE html>
<html xmlns:og="http://opengraphprotocol.org/schema/" xmlns:fb="http://www.facebook.com/2008/fbml" xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" class="SAF" id="global-header-light">
<head>

</head>
<body>


<div style="background-image: url(http://aka-cdn-ns.adtech.de/rm/ads/23274/HPWomenLOFT_1381687318.jpg);background-repeat: no-repeat;-webkit-background-size: 1001px 2059px; height: 2059px; width: 1001px; text-align: center; margin: 0 auto;">                      

<div style="height:2058px; padding-left:0px; padding-top:36px;">


<iframe style="height:90px; width:728px;" />



</div>
</div>

</body>
</html>

在通过此代码进行格式化之后

String url = request.getParameter("htmluri").trim();
        System.out.println("Fetching %s..."+url);

        Document doc = Jsoup.connect(url).get();
        //System.out.println(doc.html());
        Document.OutputSettings settings = doc.outputSettings();
        settings.prettyPrint(false);
        //settings.escapeMode(Entities.EscapeMode.base);
        settings.charset("ASCII");
        String html = doc.html();
        html = StringEscapeUtils.unescapeHtml(html);
        System.out.println(html);

       // String html = doc.html();

        System.out.println(html);

我得到这个HTML

<!DOCTYPE html><html xmlns:og="http://opengraphprotocol.org/schema/" xmlns:fb="http://www.facebook.com/2008/fbml" xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" class="SAF" id="global-header-light"><head>

</head>
<body>


<div style="background-image: url(aol.jpeg);background-repeat: no-repeat;-webkit-background-size:100720; height:720; width:100; text-align: center; margin: 0 auto;">                      

<div style="height:100; padding-left:0px; padding-top:36px;">


<iframe style="height:90px; width:728px;"></iframe>



</div>
</div>

</body>
</html></div></div></body></html>

所以有更多的重复关闭div体和html标签。虽然他们不会伤害页面的渲染我猜。有没有办法摆脱它。

我回来了：P。你只需再次解析你拥有的html，这样jsoup将删除任何额外的结束标记

String url = request.getParameter("htmluri").trim();
System.out.println("Fetching %s..."+url);

Document doc = Jsoup.connect(url).get();
Document.OutputSettings settings = doc.outputSettings();
settings.prettyPrint(false);
settings.charset("ASCII");
String html = doc.html();
html = StringEscapeUtils.unescapeHtml(html);
html = Jsoup.parse(html).html();   //This will take care of any extra closing tags 
System.out.println(html);

输出

Fetching %s...http://iqtestsites.adtech.de/pictelatest/custombkgd/StylelistDevil.html
<!DOCTYPE html>

   <div style="height:1050px; width:300px; padding-left:681px; padding-top:200px;"> 
    <iframe style="height:1050px; width:300px;"></iframe> 
   </div> 
  </div>  
 </body>
</html>
