The System.Xml namespace provides standards-based support for processing XML. The supported standards are:

Members of System.Xml Namespace

Classes
Class Description
class NameTable Implements a single-threaded XmlNameTable. 
class XmlAttribute Represents an attribute. Valid and default values for the attribute are defined in a DTD or schema. 
class XmlAttributeCollection Represents a collection of attributes that can be accessed by name or index. 
class XmlCDataSection Represents a CDATA section.  
class XmlCharacterData Provides text manipulation methods that are used by several classes.  
class XmlComment Represents the content of an XML comment. 
class XmlConvert Encodes and decodes XML names and provides methods for converting between common language runtime types and XML Schema definition language (XSD) types. When converting data types the values returned are locale independent. 
class XmlDeclaration Represents the XML declaration node: <?xml version='1.0' ...?>. 
class XmlDocument Represents an XML document. 
class XmlDocumentFragment Represents a lightweight object that is useful for tree insert operations. 
class XmlDocumentType Represents the document type declaration. 
class XmlElement Represents an element. 
class XmlEntity Represents an entity declaration: <!ENTITY ... >. 
class XmlEntityReference Represents an entity reference node. 
class XmlException Returns detailed information about the last exception.  
class XmlImplementation Defines the context for a set of XmlDocument objects. 
class XmlLinkedNode Gets the node immediately preceding or following this node. 
class XmlNamedNodeMap Represents a collection of nodes that can be accessed by name or index. 
class XmlNamespaceManager Resolves, adds and removes namespaces to a collection and provide scope management for these namespaces. This class is used by the XsltContext and XmlReader classes. 
class XmlNameTable Table of atomized string objects. 
class XmlNode Represents a single node in the XML document. 
class XmlNodeChangedEventArgs Provides data for the XmlDocument.NodeChanged, XmlDocument.NodeChanging, XmlDocument.NodeInserted, XmlDocument.NodeInserting, XmlDocument.NodeRemoved and XmlDocument.NodeRemoving events. 
class XmlNodeList Represents an ordered collection of nodes. 
class XmlNodeReader Represents a reader that provides fast, non-cached forward only access to XML data in an XmlNode 
class XmlNotation Represents a notation declaration: <!NOTATION ... >. 
class XmlParserContext Provides all the context information required by XmlTextReader or XmlValidatingReader to parse an XML fragment. 
class XmlProcessingInstruction Represents a processing instruction, which XML defines to keep processor-specific information in the text of the document. 
class XmlQualifiedName Represents an XML qualified name. 
class XmlReader Represents a reader that provides fast, non-cached, forward-only access to XML data. 
class XmlResolver Resolves external XML resources named by a URI. 
class XmlSignificantWhitespace Represents white space between markup in a mixed content mode or white space within an xml:space= 'preserve' scope. This is also referred to as significant white space. 
class XmlText Represents the text content of an element or attribute. 
class XmlTextReader Represents a reader that provides fast, non-cached, forward-only access to XML data. 
class XmlTextWriter Represents a writer that provides a fast, non-cached, forward-only way of generating streams or files containing XML data that conforms to the W3C Extensible Markup Language (XML) 1.0 and the Namespaces in XML recommendations. 
class XmlUrlResolver Resolves external XML resources named by a URI. 
class XmlValidatingReader Represents a reader that provides DTD, XML-Data Reduced (XDR) schema, and XML Schema definition language (XSD) schema validation. 
class XmlWhitespace Represents white space in element content. 
class XmlWriter Represents a writer that provides a fast, non-cached, forward-only means of generating streams or files containing XML data that conforms to the W3C Extensible Markup Language (XML) 1.0 and the Namespaces in XML recommendations. 

Interfaces
Interface Description
interface IHasXmlNode Enables a class to return an XmlNode from the current context or position. 
interface IXmlLineInfo Provides an interface to enable a class to return line and position information. 

Delegates
Delegate Description
delegate XmlNodeChangedEventHandler Represents the method that handles XmlDocument.NodeChanged, XmlDocument.NodeChanging, XmlDocument.NodeInserted, XmlDocument.NodeInserting, XmlDocument.NodeRemoved and XmlDocument.NodeRemoving events. 

Enumerations
Enumeration Description
enumeration EntityHandling Specifies how entities are handled. 
enumeration Formatting Specifies formatting options for the XmlTextWriter. 
enumeration ReadState Specifies the state of the reader. 
enumeration ValidationType Specifies the type of validation to perform. 
enumeration WhitespaceHandling Specifies how white space is handled. 
enumeration WriteState Specifies the state of the XmlWriter. 
enumeration XmlNodeChangedAction Specifies the type of node change. 
enumeration XmlNodeOrder Describes the document order of a node compared to a second node. 
enumeration XmlNodeType Specifies the type of node.  
enumeration XmlSpace Specifies the current scope. 
enumeration XmlTokenizedType Represents the XML type for the string. This allows the string to be read as a particular XML type, for example a CDATA section type.
