Jsoup.parse（）。body（）。getAllElements（）将标签加倍
[英]Jsoup.parse().body().getAllElements() doubles tags
问题描述
Is there any reason why this JSoup doubles the contents of the body tag here? 
是否有任何原因导致此JSoup在此处将body标签的内容加倍？
public static void main(String[] args) {
Jsoup.parse(myHtmlString).body().getAllElements()
}
It does just happen for this html code: 这确实发生在此html代码中：
<html>
<head>
<style> p{margin-bottom:0px;margin-top:0px;} body{font-family:Arial;font-size:10pt;} </style>

Its obvious and perfect. 它的明显和完美。
Infact it doesn't double but repeats the Elements as many times as its depth wrt to the reference Node 实际上，它不会加倍，但会重复Elements到参考Node深度的次数
Each and every Node under body is considered as Element including body , until it reaches the leaf Node . body之下的每个Node都被视为包括body在内的Element ，直到到达叶Node为止。
If you consider the text <b>Betreff:</b> It is repeated 7 times since, it is 7 levels below the root ( <body> ) , and also it is the child with greater depth in the tree. 如果考虑文本<b>Betreff:</b> ， <b>Betreff:</b>被重复7次，位于根（ <body> ）下方7个级别，并且也是树中深度更大的子级。
body > div >div > div > p > span >b
