A node can contain text, attributes, other nodes (hence, the hierarchical nature of XML), and a few other specialized things (such as processing instructions and comments).

节点可以包含文本、属性、其他节点(因此形成XML的层次结构)以及其他一些特殊的东西(比如处理指令和注释)。

Processing instructions and comments are also reduced to special tag names that are not available in XML: PI for the former, comment for the latter.
