You work as a Web Developer at Certkiller.com. You are in the process of creating a Webapplication using Microsoft ASP.NET 3.5. 
The Web application will be used to displays sales data from an XML file. The XML file does notcontain an inline schema. You notice that a DataSet-compatible schema is stored in an XSD file.The schema identifies a subset of the nodes that exist in the XML file. You should not make anymodifications to this schema. 
You decide to load the XML information in order for it to be navigated relationally and with the XMLDocument Object Model （DOM）.
