XML (eXtensible Markup Language) is a markup language used to store and transport data. It is designed to be both human-readable and machine-readable.
The primary classes include XmlReader, XmlWriter, XmlDocument, and XDocument (from LINQ to XML).
The XmlDocument class represents an XML document in memory and allows for the creation, manipulation, and navigation of the document’s elements and attributes.
Answer: XmlReader is a fast, forward-only, read-only cursor for processing XML data, while XmlDocument loads the entire XML document into memory, allowing for modification and navigation.
What is LINQ to XML and how is it different from XmlDocument?
LINQ to XML (using the XDocument class) is a LINQ-based approach to XML that provides a more intuitive and flexible way to work with XML data through a modern API that supports querying and transforming XML using LINQ syntax
You can load an XML file using XDocument.Load("filePath"), where "filePath" is the path to the XML file
Answer: The XmlSerializer class is used to serialize objects into XML and deserialize XML into objects. It is commonly used for converting between .NET objects and their XML representation.
Answer: XPath is a language for selecting nodes from an XML document. In .NET, XPath expressions can be evaluated using the XPathNavigator class or methods provided by XmlDocument.
Answer: You can create an XML element using the XElement class, for example: XElement element = new XElement("ElementName", "Content");.
Answer: The XmlWriter class is used for writing XML data to a stream, file, text writer, or string builder in a fast, forward-only, non-cached manner.
