Jsoup获取类名 [英] Jsoup get class name

问题描述

我用解析元素

 Elements input1 = pageListingParsed.select("form[name=MailForm] textarea");

示例输出为:

 <textarea name="dec13d35885064571998cc1c81facc28" rows="5" wrap="virtual" class="form-control c-545599b92f2d2b5a09f21c06d490e810"></textarea>

如何获取课程名称?在这种情况下，我需要将c-545599b92f2d2b5a09f21c06d490e810分配给变量.

How can I get the class names? In that case I would need to assign the c-545599b92f2d2b5a09f21c06d490e810 to a variable.

谢谢

推荐答案

如果确定元素大小为1，则需要获取第一个Element并对其使用方法attr(...):

if you are sure the element size is 1, then you need to get the first Element and use method attr(...) for it:

Element e = input1.get(0);
System.out.println(e.attr("class"));

输出将是:

form-control c-545599b92f2d2b5a09f21c06d490e810

form-control c-545599b92f2d2b5a09f21c06d490e810

仅获得第二部分，您可以在其上简单地使用String.split(regex)方法.

to only get the second part, you can simply use String.split(regex) method on it.

例如

String s = "form-control c-545599b92f2d2b5a09f21c06d490e810";
System.out.println(s.contain(" ")? s.split(" ")[1] : s);

输出:

c-545599b92f2d2b5a09f21c06d490e810

c-545599b92f2d2b5a09f21c06d490e810
