jsoup根据div标签id获取值

I have an html which has tags as follows.

我有一个html,其标签如下。

 parent   <li class="pro pic notSold" status="0" >
 child      <ul><li></li><ul>
 parent   <li class="pro pic soldOut" status="-1" >
 child      <ul><li></li><ul>

there are multiple parent

有多个父母

tags as above. I want my loop to work for all

标签如上。我希望我的循环适用于所有人

parent tags. I tried, Elements indProducts = html.select("li"); This was pulling even the child li. I dont want that. I want to code such that if the

父标签。我试过,Elements indProducts = html.select(“li”);这甚至拉动了孩子李。我不想那样。我想编写这样的代码,如果

class starts with pro pic, then it would be considered else skip. What should I do? Is there a select clause that works similar to "like" or something like that.

课程从专业图片开始,然后将被认为是跳过。我该怎么办?是否有一个类似于“喜欢”或类似的选择子句。

Yes, jSoup provides something similar to like. Check out this selector usage link.

是的,jSoup提供类似的东西。查看此选择器使用链接。

You could try something like this:

你可以尝试这样的事情:

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.select.Elements;


public class JSoupTest 
{
    public static void main(String[] args) 
    {
         String html =   "<li class='pro pic notSold' status='0' >";
         html+=      "<ul><li></li><ul>";
         html+=   "<li class='pro pic soldOut' status='-1' >";
         html+=      "<ul><li></li><ul>";

         Document doc = Jsoup.parse(html);
         Elements elems = doc.select("[class^=pro pic]");

        System.out.println(elems.size());
    }
}

Output = 2

输出= 2

Note: Your class starting with pro pic is too generic and will return the outermost parent (and also one inner child).

注意:以pro pic开头的课程过于通用,将返回最外层的父级(以及一个内部子级)。

This is more precise, just selects tags li for which the class attributes starts with pro pic:

这更精确,只需选择标签li,类属性以pro pic开头:

Elements litags = yourcontent.select("li[class^=pro pic]");

Or if you want to be sure that you take only the first level of childrens you can use this:

或者,如果您想确保只使用第一级儿童,您可以使用:

Elements litags = yourcontent.select(" > li[class^=pro pic]");

*PS: I tested with yourcontent as Element. I don't know if works for Elements.

* PS:我测试了你的内容作为元素。我不知道是否适用于Elements。
