我如何用Jsoup解析这个HTML [英] How do I parse this HTML with Jsoup

问题描述

我试图提取了解你的拖拉机和壳牌石油公司1955？请记住，这只是整个代码的一部分，并且有多个H2 / H3标签。我想从所有H2和H3标签中获取数据。

继承HTML： http：//我现在的代码是：

  ArrayList< String> arrayList = new ArrayList< String>（）; 
 Document doc = null; 
尝试{
 
 doc = Jsoup.connect（http://primo.abdn.ac.uk:1701/primo_library/libweb/action/search.do?dscnt=0&scp .scps =范围％3A％28ALL％29&安培; frbg =安培;标签= default_tab&安培; dstmp = 1332103973502&安培; SRT =秩&安培; CT =搜索和安培;模式=基本&安培;达姆=真安培; INDX = 1&安培; TB = T&安培; VL（freeText0 ）=拖拉机&安培; FN =搜索&安培; VID = ABN_VU1\" ）得到（）; 
元素标题= doc.select（h2.EXLResultTitle span）; 
 
 for（Element src：heading）{
 String j = src.text（）; 
 System.out.println（j）; //检查进入数组
 arrayList.add（j）; 
} 
  

我将如何提取了解您的拖拉机和壳牌石油公司。 ？感谢您的帮助！

解决方案

您的选择器只会选择< span> 元素，它们在< h2 class =EXLResultTitle> 中，而实际上 需要那些< h2> ; 元素自己。因此，只需从选择器中移除 span 即可：

 元素标题= doc 。选择（ h2.EXLResultTitle）; （元素标题：标题）{
 System.out.println（heading.text（））; 
 
 
} 
  

您应该能够为< ; h3 class =EXLResultAuthor> 你自己根据学到的经验。 b $ b

I am trying to extract "Know your tractor" and "Shell Petroleum Company.1955"? Bear in mind that that is just a snippet of the whole code and there are more then one H2/H3 tag. And I would like to get the data from all the H2 and H3 tags.

Heres the HTML: http://i.stack.imgur.com/Pif3B.png

The Code I have just now is:

    ArrayList<String> arrayList  = new ArrayList<String>();
    Document doc = null;
 try{

     doc = Jsoup.connect("http://primo.abdn.ac.uk:1701/primo_library/libweb/action/search.do?dscnt=0&scp.scps=scope%3A%28ALL%29&frbg=&tab=default_tab&dstmp=1332103973502&srt=rank&ct=search&mode=Basic&dum=true&indx=1&tb=t&vl(freeText0)=tractor&fn=search&vid=ABN_VU1").get();
     Elements heading = doc.select("h2.EXLResultTitle span"); 

     for (Element src : heading) {
            String j = src.text();
            System.out.println(j);  //check whats going into the array 
            arrayList.add(j);
     }

How would I extract "Know your tractor" and "Shell Petroleum Company.1955"? Thanks for your help!

解决方案

Your selector only selects <span> elements which are inside <h2 class="EXLResultTitle">, while you actually need those <h2> elements themself. So, just remove span from the selector:

Elements headings = doc.select("h2.EXLResultTitle");

for (Element heading : headings) {
    System.out.println(heading.text());
}

You should be able to figure the selector for <h3 class="EXLResultAuthor"> yourself based on the lesson learnt.
