In response to your first question regarding XML:
1. Start Visual Studio 2005 or Visual Studio .NET.
2. Create a new Visual C# Console Application. You proceed directly to the "Complete code listing" section or continue through these steps to build the application.
3. Make sure that the project contains a reference to the System.Xml.dll assembly.
4. Specify the using directive on the System.Xml namespace so that you are not required to qualify XmlTextReader declarations later in your code. You must use the using directive before any other declarations.
5. Create an instance of an XmlTextReader object, and populate it with the XML file. Typically, the XmlTextReader class is used if you need to access the XML as raw data without the overhead of a DOM; thus, the XmlTextReader class provides a faster mechanism for reading XML. The XmlTextReader class has different constructors to specify the location of the XML data. The following code creates an instance of the XmlTextReader class and loads the Books.xml file. Add the following code to the Main procedure of Class1.
XmlTextReader reader = new XmlTextReader ("books.xml");
6. Read through the XML. (Note that this step demonstrates an outer "while" loop, and the next two steps demonstrate how to use that loop to read the XML.) After you create the XmlTextReader object, use the Read method to read the XML data. The Read method continues to move through the XML file sequentially until it reaches the end of the file, at which point the Read method returns a value of "False."
// Do some work here on the data.
