时间：2022-10-31 10:34:18

I have a html line where there are tags inside tags, a single tag my contain multiple class. I need to extract the text with single class name(i know only one class name)

我有一个html行,其中标签内有标签,单个标签我包含多个类。我需要用单个类名提取文本(我只知道一个类名)

<p class="Body1"><span class="style3"></span><span class="style1">W</span><span class="Allsmall style5">extract this text </span><span class="style5">unwanted text </span></p>

I know the class name Allsmall alone i want to extract the text "extract this text" from the html line using Jsoup in java.

我知道单独的类名Allsmall我想用java中的Jsoup从html行中提取文本“extract this text”。

You can use the selector syntax to retrieve a specific element based on its CSS class attribute:

您可以使用选择器语法根据其CSS类属性检索特定元素:

Document doc = Jsoup.parse(
  new File("input.html"), 
  "UTF-8", 
  "http://sample.com/");

Element allSmallSpan = doc.select("span.Allsmall").first(); // Retrive the first <span> element which belongs to "Allsmall" class
