兒童的JSoup格式輸出

Question

我正在解析帶有許多這樣的條目的文檔（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>

我可以提取歌曲的標題和藝術家的兩個單獨的列表，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，現在的輸出如下所示：

<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

我希望它看起來像：

1 - Song - Artist
2 - Song - Artist
etc

我一直在尋找相關的帖子並嘗試過，但是我還不太清楚：

        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");
        }

當前會輸出一首空白歌曲，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: 

兩個主要問題仍然懸而未決：

• 如何打印歌曲的歌手？ 為什么是空白？
• 我該如何添加編號（這是次要的，但是會很好）

非常感謝！

通過使用更大的父代解決了第一個問題：

    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");
    }

現在輸出如下所示：

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

關於如何清除％amp的任何想法； 並添加編號？

Answer 1

像這樣解決它：

    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");
    }
