java - 如何从HTML获取链接， `doc.select`的正确用法

Question

我想从 HTML 代码中获取链接。此页面的代码:https://www.valorebooks.com/books/fiction/fantasy

 <div class="sub_bar sub_bar_no_pointer"> 
         <span class="showing">Showing 1 - 50 of 28705 - Browse More Fantasy Books for Sale</span> 
         <div class="paginator" id="pg"> 
          <a href="/books/fiction/fantasy" class="active">1</a> 
          <a href="/books/fiction/fantasy?page=2">2</a> 
          <a href="/books/fiction/fantasy?page=3">3</a> 
          <a href="/books/fiction/fantasy?page=4">4</a> 
          <a href="/books/fiction/fantasy?page=5">5</a> 
          <span class="paginatorText">...</span> 
          <a href="/books/fiction/fantasy?page=575">575</a> 
          <span class="paginatorText">|</span> 
          <a href="/books/fiction/fantasy?page=2" class="spriteButton arrow     next icon-right-open"></a>
         </div> 
        </div> 

我找到了如何获取链接的示例，但我不确定应该在 doc.select("div.paginator"); 中编写什么。正确与否，也许我应该用另一种方式来写。

    Elements myLink = doc.select("div.paginator");      

    int number = 0;
    for (Element links : myLink) {
        Elements a = myLink.select("a[href]");                      // get links
        number = Integer.parseInt(a.get(a.size() - 2).text());
    }
    for (int i = 0; i < 20; i++) {
        getData(url + i);
    }
}

目前尚不清楚您想要实现什么目标。

要打印所有链接的字符串，您可以这样做:

System.out.println(doc.select("div.paginator").select("a[href]").toString());

对于链接的 Elements 数组:

Elements theLinks = doc.select("div.paginator").select("a[href]");
