Jsoup.parse().body().getAllElements() 双打标签

【发布时间】：2018-09-05 20:37:18
【问题描述】：

这个JSoup有什么理由把body标签的内容加倍吗？

public static void main(String[] args) {
    Jsoup.parse(myHtmlString).body().getAllElements()
}

这确实发生在这段 html 代码中：

<html>
 <head> 
  <style> p{margin-bottom:0px;margin-top:0px;} body{font-family:Arial;font-size:10pt;} </style> 
 </head> 
 <body>

以上解析方式的结果，并不是说这里只是body部分的内容：

我正在使用 Java 6 和 Jsoup 1.7.2。

    【解决方案1】：

    它明显而完美。

    事实上，它不会翻倍，而是重复 Elements 的次数与其深度 w.r.t 到参考 Node 的次数相同

    body 下的每个Node 都被视为Element，包括body，直到它到达叶子Node。

    如果你考虑文本&lt;b&gt;Betreff:&lt;/b&gt;，它重复了7次，它比根(&lt;body&gt;)低7级，也是树中深度更大的孩子。

    body &gt; div &gt;div &gt; div &gt; p &gt; span &gt;b
