Jsoup：如何在很多元素中獲取ID和href

Question

我需要在所有元素中獲取ID和href（如圖中彩色框所示）。我不知道如何正確地尋找路徑並提取所需的信息。我怎樣才能做到這一點？

Answer 1

通過標識和標籤，直到你到了相關的標籤，然後通過屬性讓他們選擇。檢查下面的代碼片段：

Document doc = Jsoup.parse("html_file"); 

Element loginform = doc.getElementById("search_result_container"); 
Elements inputElements = loginform.getElementsByTag("div"); 
Element secondDiv = inputElements.get(1); 
Elements hyperLinks = secondDiv.getElementsByTag("a"); 

for (Element alink : hyperLinks) { 
    String href = alink.attr("href"); 
    String id = alink.attr("id");    
} 

Answer 2

好的，我做到了。有用！！感謝SUNNYben，你給了我正確的輸入！

這裏是我的解決方案，代碼：

import java.io.File; 
import java.io.FileInputStream; 
import java.io.FileWriter; 
import java.io.IOException; 
import java.io.InputStream; 
import org.jsoup.Jsoup; 
import org.jsoup.nodes.Document; 
import org.jsoup.nodes.Element; 
import org.jsoup.select.Elements; 

public class Steam_GameID_Links 
{ 
    public static void main(String[] args) 
    { 
     Steam_GameID_Links wc = new Steam_GameID_Links(); 
     try 
     { 
      String url = "http://store.steampowered.com/search/?sort_by=_ASC&category1=998&page=1"; 
      Document document = Jsoup.connect(url).get(); 
      // nur die Spielnamen 
      Elements howMuchPages = document.select(".search_pagination_right"); 
      String[] stuff = howMuchPages.text().split(" "); 
      String tmp = stuff[4].replace(" ", "").replace(".", ""); 
      StringBuilder sb = new StringBuilder(); 
      for(int i = 0; i < tmp.length(); i++) 
      { 
       if(Character.isDigit(tmp.charAt(i))) 
       { 
        sb.append(tmp.charAt(i)); 
       } 
      } 
      String last = sb.toString().trim();; 
      int lastPages = Integer.parseInt(last); 
      int counter = 0; 
      for(int i = 1; i < lastPages + 1; i++) 
      { 
       url = "http://store.steampowered.com/search/?sort_by=_ASC&category1=998&page=" + i; 
       document = Jsoup.connect(url).get(); 
       // waehlt zunaechst den ElternKnoten: <div id="search_result_container"> 
       Element parentNode = document.getElementById("search_result_container"); 
       Elements childNodes = parentNode.getElementsByAttribute("data-ds-appid"); 
       for(Element alink : childNodes) 
       { 
        String href = alink.attr("href"); 
        String id = alink.attr("data-ds-appid"); 
        String name = alink.getElementsByClass("title").text(); 
        System.out.println("Spiel: " + name + ", ID: " + id + ", SpieleLink: " + href); 
        // wc.writeSpielNameIDLink("Spiel: " + name + ", ID: " + id + ", SpieleLink: " + href + "\n"); 
       } 
      } 
     } 
     catch(IOException e) 
     { 
      e.printStackTrace(); 
     } 
    }
