how to append elements into an xml file?

How big a file?
Less than 500kb?

This is because you have two options in reading XML files in .net - you can use a XmlDocument or an XmlReader/XmlWriter.

The XmlDocument is way easier, but since it loads the entire file into memory (and constructs an in-memory tree representation of your document) it's slow and consumes a lot of memory. So it's best used for files less that 500kb or so (that's just a number I made up - your experience may indicate a different one). You would load the file into your XmlDocument, and append your new nodes using CreateElement and AppendChild methods.

The XmlReader/XmlWriter are actually abstract base classes - you'll actually need to instantiate one of XmlTextReader, XmlValidatingReader, or XmlNodeReader. In the case of a writer, you'll use XmlTextWriter.
