Part II: LINQ to XML
The XDocument class contains a number of methods that are identical to XElement class methods. They??™re
described in the following table.
Method Description
AddAnnotation Adds an annotation to a given XElement. In general terms, this method
adds an object to the annotation of the corresponding XObject (the
current node or attribute in the tree).
CreateReader Creates an XmlReader (a fast, forward-only copy of the XML document)
of the current node.
CreateWriter Creates an XmlWriter of the XML document that provides the
capability to modify the XML document, such as adding nodes or
attributes. The XmlWriter is a fast, forward-only mechanism for
creating files of the in-memory XML document.
DescendantNodes Returns a collection of all descendant nodes of the entire document or
the current node/element.
Element In an ordered XML document, Element returns the first element that
matches the specified element name.
IsAfter Returns a Boolean value that specifies whether the current node
appears after a specified node.
