Question

我正在解析一个包含许多条目的文档（使用JSoup）

 <span class="chart_position position-up position-greatest-gains">1</span>
            <h1>Beauty And A Beat</h1>
        <p class="chart_info">
      <a href="/artist/305459/justin-bieber">Justin Bieber Featuring Nicki Minaj</a>            <br>
      Beauty and a Beat          </p>

我可以提取两首单独的歌曲名称和艺术家名单，如下所示：

    Elements song = doc.select("div.chart_listing h1");
    System.out.println("song: " + song);

    Elements li = doc.select("p.chart_info a");
    System.out.println("artists: " + li.text());

但是，现在输出如下：

<h1>The Lucky Ones</h1>
<h1>Scream &amp; Shout</h1>
<h1>Clarity</h1>
<h1>We Are Young</h1>
<h1>Va Va Voom</h1>
<h1>Catch My Breath</h1>
<h1>I Found You</h1>
<h1>Sorry</h1>
<h1>Leaving</h1>
artists: Justin Bieber Featuring Nicki Minaj Kerli will.i.am & Britney Spears Nicki Minaj Kelly Clarkson The Wanted Ciara Pet Shop Boys

我希望它看起来像：

1 - Song - Artist
2 - Song - Artist
etc

我一直在查看相关帖子并尝试过这个，但我还没弄明白：

        Elements parents = doc.select("div.chart_listing h1");
        for (Element parent : parents)
        {
            Elements categories = parent.select("p.chart_info a");
            System.out.print("song: " + parent + " - ");
            System.out.print("artist: " + categories.text() + "\n");
        }

目前输出一首空白歌曲，如下所示：

song: <h1>Beauty And A Beat</h1> - artist: 
song: <h1>The Lucky Ones</h1> - artist: 
song: <h1>Scream &amp; Shout</h1> - artist:

仍有两个主要问题：

如何打印属于该歌曲的艺术家？为什么会这样？
如何添加编号（这是次要的，但会很好）

非常感谢！

--- EDIT

通过使用更大的父级来解决第一个问题：

    Elements parents = doc.select("article.song_review");
    for (Element parent : parents)
    {
        Elements titles = parent.select("h1");
        Elements categories = parent.select("p.chart_info a");
        System.out.print("song: " + titles + " - ");
        System.out.print("artist: " + categories.text() + "\n");
    }

现在输出如下：

song: <h1>Beauty And A Beat</h1> - artist: Justin Bieber Featuring Nicki Minaj
song: <h1>The Lucky Ones</h1> - artist: Kerli
song: <h1>Scream &amp; Shout</h1> - artist: will.i.am & Britney Spears

关于如何清理％amp的任何想法;并添加编号？

Answer 1

解决这个问题：

    Elements parents = doc.select("article.song_review");
    for (Element parent : parents)
    {
        Elements position = parent.select("span.chart_position");
        Elements titles = parent.select("h1");
        Elements categories = parent.select("p.chart_info a");
        System.out.print("position: " + position.text() + " - song: " + titles.text() + " - ");
        System.out.print("artist: " + categories.text() + "\n");
    }

孩子的JSoup格式输出
