Is the XML document only exist in the form of a text file? wrong.
Common XML storage forms are:
Text file relational database binary XML database (this is a bit too much, huh, huh)
Storage XML data in text is certain in many cases, it is also the most common XML storage method, because we have access to the XML configuration file in J2EE. If it is not text, we will change it. Don't you turn a little? Only when the text is used, it needs to be converted each time, affecting the efficiency of the execution. So usually we use some automated tools when you do a project, do some of our XML before system running or debugging.
In this way, we really can't think of it.
