Hi Ritesh,
                  You need to decide the approach you want to select. There are two ways to do it. They are

DOM parsing.
SAX Parsing.

You can use DOM parsing for small xml files. For larger files use sax parsing. MsXML dll from microsoft provides the COM implementation for parsing. You will msxml SDK for the implementation.
