There are two simple methods in my application: one is reading xml file by using DOM method and the other is reading the same file using SAX method. I’m not gonna explain the difference between DOM & SAX, only telling this that in DOM , a parser must read the whole file u r reading before u can read anything. In other words the file is loaded into the memory of your application, where DOM makes an object model of it, then u can traverse throw the elements of this object model & receive/update needed information. SAX method, reads file step by step, so it is a resource benefit . Of course there can be said a lot about that but if u r interested I’m sure u’ll find more complex info. I made this example when I was studying XML and its two models/interfaces for making parsers – DOM & SAX and it was interesting for me to use them throw NET.
