PI则是为处理xml/sgml的软件给出的提示。

发帖数: 144 | 6 I guess you will get all the content in your <> by getDocType
and nothing from getProcessInstruction.
from specification, PItarget can not have any name with
(('X' | 'x') ('M' | 'm') ('L' | 'l')).

发帖数: 22 | 7 somewhat confused....
don't know about getDocType() and getProcessingInstruction()
also can't find them in DOM API.
PI is a type of node, just like Element, Attributer,
Text......
Document is container, owning a bundle of nodes,
so there should be some sort of different between them.
