如何使用jsoup從html文件中的強標記檢索數據？

Question

我有這樣

<div class="bs-example"> 
    <div class="panel panel-primary"> 
    <div class="panel-heading"> 
     <h3 class="panel-title">ABC</h3> 
    </div> 
    <div class="panel-body"> 
     <div class="slimScroller" style="height:280px; position: relative;" data-rail-visible="1" data-always-visible="1"> 
     <strong>Name:</strong> 
     <a href="https://ABC"> </a><br /> 
     <strong>ID No:</strong> XXXXX<br /> 
     <strong>Status:</strong> ACTIVE<br /> 
     <strong>Class:</strong> 5<br /> 
     <strong>Category:</strong> A<br /> 
     <strong>Marks:</strong> 500<br /> 
     </div> 
    </div> 
    </div> 
</div> 

一些HTML數據我想爲（多學生數據）輸出：

Name: ABC 
ID No.: XXXXX 
Status: Active 
Class: 5 
Category: A 
Marks: 500 

如何使用jsoup或任何其他方式獲得這些數據？請幫忙。

Answer 1

您可以使用Element.nextElementSibling（）或/和Element.nextSibling（）來獲取所需的輸出。

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

public class Exam { 
    public static void main(String[] args) { 
    String html = "<div class=\"bs-example\">" + 
        " <div class=\"panel panel-primary\">" + 
        " <div class=\"panel-heading\">" + 
        "  <h3 class=\"panel-title\">ABC</h3>" + 
        " </div>" + 
        " <div class=\"panel-body\">" + 
        "  <div class=\"slimScroller\" style=\"height:280px; position: relative;\" data-rail-visible=\"1\" data-always-visible=\"1\">" + 
        "  <strong>Name:</strong>" + 
        "  <a href=\"https://ABC\"> </a><br />" + 
        "  <strong>ID No:</strong> XXXXX<br />" + 
        "  <strong>Status:</strong> ACTIVE<br />" + 
        "  <strong>Class:</strong> 5<br />" + 
        "  <strong>Category:</strong> A<br />" + 
        "  <strong>Marks:</strong> 500<br />" + 
        "  </div>" + 
        " </div>" + 
        " </div>" + 
        "</div>"; 

    Document doc = Jsoup.parse(html); 
    Elements eles = doc.select("div.slimScroller strong"); 
    for(Element e :eles) 
    System.out.println(e.text() + 
         (e.nextElementSibling().tagName().equals("a")? 
         e.nextElementSibling().attr("href").replace("https://", ""): 
         e.nextSibling().toString())); 
    } 
} 

Answer 2

下面的代碼應提供輸出基於指定了你的評論，說明您的a標籤如何：

private static void printStudentInfo(Document document){ 
    Elements students = document.select("div.slimScroller strong"); 

    for(Element student : students){ 
     System.out.print(student.text()); 

     System.out.println(student.nextElementSibling().tagName().equals("a") ? 
       student.nextElementSibling().text() : student.nextSibling().toString()); 
    } 
}
