XML中的根节点是什么？-WhatistherootnodeinXML?

problem is when I continue the rest of the reading I thought I have misunderstand what root element is. According to my knoweledge root node is node.

问题是，当我继续阅读其余部分时，我认为我误解了根元素是什么。根据我的知识，根节点是 节点。

But in the book I find next this

但在书中，我发现了下一个

Unlike other nodes, the root node has no parent. It always has at least one child, the document element. The root node also contains comments or processing instructions that are outside the document element. In our sample document, the two processing instructions named xmlstylesheet and cocoon-process are both children of the root node, as are the comment that appears before the tag and the comment that appears after the tag.

与其他节点不同，根节点没有父节点。它始终至少有一个子元素，即文档元素。根节点还包含文档元素之外的注释或处理指令。在我们的示例文档中，名为xmlstylesheet和cocoon-process的两个处理指令都是根节点的子节点，标记之前显示的注释和标记之后显示的注释也是如此。

accordning to that whole document is considered as root. If so what is ? It is clear that processing instructions and comments are not child of node.

根据整个文件被视为根。如果是的话是什么？很明显，处理指令和注释不是节点的子节点。
