XCData

Represents a text node that contains CDATA.
XComment

Represents an XML comment.
XContainer

Represents a node that can contain other nodes.
XDeclaration

Represents an XML declaration.
XDocument

Represents an XML document. For the components and usage of an XDocument object, see XDocument Class Overview.
XDocumentType

Represents an XML Document Type Definition (DTD).
XElement

Represents an XML element. See XElement Class Overview and the Remarks section on this page for usage information and examples.

Remarks

Using LINQ to XML, you can:

  • Load XML from files or streams.

  • Serialize XML to files or streams.

  • Create XML trees from scratch using functional construction.

  • Query XML trees using LINQ queries.

  • Manipulate in-memory XML trees.

  • Validate XML trees using XSD.

  • Use a combination of these features to transform XML trees from one shape into another.
