这个JSoup在这里加倍body标签的内容有什么原因吗？

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

它确实发生在这个 html 代码中：

<html>
 <head> 
  <style> p{margin-bottom:0px;margin-top:0px;} body{font-family:Arial;font-size:10pt;} </style> 
 </head> 
 <body> 
  <div class="wordsection1">

以上解析方法的结果，并不是说这里只是body部分的内容：

<body> 
 <div class="wordsection1">

它明显而完美。

事实上，它不会翻倍，而是重复Elements 与参考深度一样多的次数Node

每一个Node下body都被认为是Element包括在内body，直到它到达叶子Node。

如果考虑文本<b>Betreff:</b>It 重复 7 次，它在根 ( <body>) 之下 7 级，也是树中深度更大的子节点。

body > div >div > div > p > span >b
