As a developer of J2EE, in fact, we face a variety of XML files and applications every day, you can say that XML has almost become our homewin, from Ant's build.xml to Web Server's web.xml to the Struts framework Struts-config to EJB application EJB-JAR.XML to the persistent layer framework, such as SQLMAPS to the RPC, XML has penetrated every corner of our usual development work, this fact fully illustrates the powerful function of XML and vitality. (XML applications are of course far from these J2EE's stuff)
However, how much do we really understand XML? Maybe we didn't really think about such a problem, usually we just learn a kind of XML configuration file, and then embraced, just, even in some cases, we can generate directly through graphical interface or automation tools. The required XML document. When I found myself for nearly four years of Java, I was actually surprised, then I was surprised, then I thought, then I thought, I would like to bring XML's foundation to the head, so I now have now The blog article see.
Basically, I will record the most basic XML concepts and usage, and use as much as possible to make yourself with everyone to recall. After these basic things, we will return to the head to see how our daily contacts will have some more in-depth understanding.
This learning note will be roughly divided into three pieces: I - XML's basic concept, II - XML usage / use, III - Java for processing XML API. I will update this topic.
