What are the derived classes from xmlReader and xmlWriter



What are the derived classes from xmlReader and xmlWriter..

Answer / kirti

Both XmlReader and XmlWriter are abstract base classes, which define the functionality that all derived classes must support.

There are three concrete implementations of XmlReader:

1.XmlTextReader

2.XmlNodeReader

3.XmlValidatingReader

There are two concrete implementations of XmlWriter:

1.XmlTextWriter

2.XmlNodeWriter

XmlTextReader and XmlTextWriter support reading data to/from text-based stream, while XmlNodeReader and XmlNodeWriter are designed for working with in-memory DOM tree structure. The custom readers and writers can also be developed to extend the built-in functionality of XmlReader and XmlWriter.
