"Learning Notes" XML DOM

Before learning OC when the XML is too simple, there is no content, the game resources to use the load to find is teacher fooled ~ ~

There are some problems not to be rejected, especially attributes, feel not used first, to be contented often:

Spit trough under W3school, disorderly patchwork, learning like looking for something! Of course, as a free sharing site it is still very great.

Summary from the above (the total feeling missing what):

Try after the code inside no Chinese, but also very naïve comment~~~can you understand yourself??
