How to remove all inline styles and other attributes(class,onclick) from html elements using Jsoup? 
如何使用Jsoup从html元素中删除所有内联样式和其他属性（class，onclick）？
Sample Input : 样本输入：
<div style="padding-top:25px;" onclick="javascript:alert('hi');">
This is a sample div <span class='sampleclass'> This is a sample span </span>
</div>
Sample Output : 样本输出：
<div>This is a sample div <span> This is a sample span </span> </div>
My Code (Is this is a right way or any other better approach is there?) 我的代码（这是正确的方法还是其他更好的方法？）
Document doc = Jsoup.parse(html);
Elements el = doc.getAllElements();
for (Element e : el) {
Attributes at = e.attributes();
for (Attribute a : at) {
e.removeAttr(a.getKey());
}
}

Yes, one method is indeed to iterate through the elements and call removeAttr(); 是的，一种方法确实是迭代元素并调用removeAttr();
An alternative method using jsoup is to make use of the Whitelist class (see docs ), which can be used with the Jsoup.clean() function to remove any non-specified tags or attributes from the document. 使用jsoup的另一种方法是使用Whitelist类（请参阅docs ），它可以与Jsoup.clean()函数一起使用，以从文档中删除任何未指定的标记或属性。
For example: 例如：
String html = "<html><head></head><body><div style='padding-top:25px;' onclick='javascript.alert('hi');'>This is a sample div <span class='sampleclass'>This is a simple span</span></div></body></html>";
Whitelist wl = Whitelist.simpleText();
wl.addTags("div", "span"); // add additional tags here as necessary
String clean = Jsoup.clean(html, wl);
System.out.println(clean);
Will result in the following output: 将导致以下输出：
11-05 19:56:39.302: I/System.out(414): <div>
11-05 19:56:39.302: I/System.out(414): This is a sample div
11-05 19:56:39.302: I/System.out(414): <span>This is a simple span</span>
11-05 19:56:39.302: I/System.out(414): </div>
