System.Xml namespaces

System.Xml and its child namespaces (System.Xml.Linq, System.Xml.Schema, and System.Xml.Serialization) contain types for processing XML.

This topic displays the types in the System.Xml namespaces that are included in the .NET for Windows Store apps. Note that the .NET for Windows Store apps does not include all the members of each type. For information about individual types, see the linked topics. The documentation for a type indicates which members are included in the .NET for Windows Store apps.

XmlNamespaceScope	Defines the namespace scope.
XmlNameTable	Table of atomized string objects.

XmlQualifiedName	Represents an XML qualified name.
XmlReader	Represents a reader that provides fast, non-cached, forward-only access to XML data.
XmlReaderSettings	Specifies a set of features to support on the XmlReader object created by the Create method.
XmlSpace	Specifies the current xml:space scope.
XmlWriter	Represents a writer that provides a fast, non-cached, forward-only means of generating streams or files containing XML data.
XmlWriterSettings	Specifies a set of features to support on the XmlWriter object created by the Create method.

System.Xml.Linq namespace

Types supported in the .NET for Windows Store apps	Description
Extensions	Contains the LINQ to XML extension methods.
LoadOptions	Specifies load options when parsing XML.
ReaderOptions	Specifies whether to omit duplicate namespaces when loading an XDocument with an XmlReader.
SaveOptions	Specifies serialization options.
XAttribute	Represents an XML attribute.
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.
XDocumentType	Represents an XML Document Type Definition (DTD).
XElement	Represents an XML element.
XName	Represents a name of an XML element or attribute.
XNamespace	Represents an XML namespace. This class cannot be inherited.
XNode	Represents the abstract concept of a node (element, comment, document type, processing instruction, or text node) in the XML tree.
XNodeDocumentOrderComparer	Contains functionality to compare nodes for their document order. This class cannot be inherited.
XNodeEqualityComparer	Compares nodes to determine whether they are equal. This class cannot be inherited.
XObject	Represents a node or an attribute in an XML tree.
XObjectChange	Specifies the event type when an event is raised for an XObject.
XObjectChangeEventArgs	Provides data for the Changing and Changed events.
XProcessingInstruction	Represents an XML processing instruction.
XStreamingElement	Represents elements in an XML tree that supports deferred streaming output.
XText	Represents a text node.

System.Xml.Schema namespace

Types supported in the .NET for Windows Store apps	Description
XmlSchema	An in-memory representation of an XML Schema as specified in the World Wide Web Consortium (W3C) XML Schema Part 1: Structures and XML Schema Part 2: Datatypes specifications.
XmlSchemaForm	Indicates if attributes or elements need to be qualified with a namespace prefix.

System.Xml.Serialization namespace

Types supported in the .NET for Windows Store apps	Description
IXmlSerializable	Provides custom formatting for XML serialization and deserialization.
XmlAnyAttributeAttribute	Specifies that the member (a field that returns an array of XmlAttribute objects) can contain any XML attributes.
XmlAnyElementAttribute	Specifies that the member (a field that returns an array of XmlElement or XmlNode objects) contains objects that represent any XML element that has no corresponding member in the object being serialized or deserialized.
XmlAnyElementAttributes	Represents a collection of XmlAnyElementAttribute objects.
XmlArrayAttribute	Specifies that the XmlSerializer must serialize a particular class member as an array of XML elements.
XmlArrayItemAttribute	Specifies the derived types that the XmlSerializer can place in a serialized array.
XmlArrayItemAttributes	Represents a collection of XmlArrayItemAttribute objects.
XmlAttributeAttribute	Specifies that the XmlSerializer must serialize the class member as an XML attribute.
XmlAttributeOverrides	Allows you to override property, field, and class attributes when you use the XmlSerializer to serialize or deserialize an object.
XmlAttributes	Represents a collection of attribute objects that control how the XmlSerializer serializes and deserializes an object.
XmlChoiceIdentifierAttribute	Specifies that the member can be further detected by using an enumeration.
XmlElementAttribute	Indicates that a public field or property represents an XML element when the XmlSerializer serializes or deserializes the object that contains it.
XmlElementAttributes	Represents a collection of XmlElementAttribute objects used by the XmlSerializer to override the default way it serializes a class.
XmlEnumAttribute	Controls how the XmlSerializer serializes an enumeration member.
XmlIgnoreAttribute	Instructs the Serialize method of the XmlSerializer not to serialize the public field or public read/write property value.
XmlIncludeAttribute	Allows the XmlSerializer to recognize a type when it serializes or deserializes an object.
XmlNamespaceDeclarationsAttribute	Specifies that the target property, parameter, return value, or class member contains prefixes associated with namespaces that are used within an XML document.
XmlRootAttribute	Controls XML serialization of the attribute target as an XML root element.
XmlSchemaProviderAttribute	When applied to a type, stores the name of a static method of the type that returns an XML schema and a XmlQualifiedName (or XmlSchemaType for anonymous types) that controls the serialization of the type.
XmlSerializer	Serializes and deserializes objects into and from XML documents. The XmlSerializer enables you to control how objects are encoded into XML.
XmlSerializerNamespaces	Contains the XML namespaces and prefixes that the XmlSerializer uses to generate qualified names in an XML-document instance.
XmlTextAttribute	Indicates to the XmlSerializer that the member must be treated as XML text when the class that contains it is serialized or deserialized.
XmlTypeAttribute	Controls the XML schema that is generated when the attribute target is serialized by the XmlSerializer.
