System.Xml Namespace

.NET Framework 2.0

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

The supported standards include:

  • XML 1.0 - http://www.w3.org/TR/1998/REC-xml-19980210 - including DTD support.

  • XML Namespaces - http://www.w3.org/TR/REC-xml-names/ - both stream level and DOM.

  • XSD Schemas - http://www.w3.org/2001/XMLSchema

  • XPath expressions - http://www.w3.org/TR/xpath

  • XSLT transformations - http://www.w3.org/TR/xslt

  • DOM Level 1 Core - http://www.w3.org/TR/REC-DOM-Level-1/

  • DOM Level 2 Core - http://www.w3.org/TR/DOM-Level-2/

  Class Description
Public class NameTable Implements a single-threaded XmlNameTable.
Public class XmlAttribute Represents an attribute. Valid and default values for the attribute are defined in a document type definition (DTD) or schema.
Public class XmlAttributeCollection Represents a collection of attributes that can be accessed by name or index.
Public class XmlCDataSection Represents a CDATA section.
Public class XmlCharacterData Provides text manipulation methods that are used by several classes.
Public class XmlComment Represents the content of an XML comment.
Public 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.
Public class XmlDataDocument Allows structured data to be stored, retrieved, and manipulated through a relational DataSet.
Public class XmlDeclaration Represents the XML declaration node <?xml version='1.0'...?>.
Public class XmlDocument Represents an XML document.
Public class XmlDocumentFragment Represents a lightweight object that is useful for tree insert operations.
Public class XmlDocumentType Represents the document type declaration.
Public class XmlElement Represents an element.
Public class XmlEntity Represents an entity declaration, such as <!ENTITY... >.
Public class XmlEntityReference Represents an entity reference node.
Public class XmlException Returns detailed information about the last exception.
Public class XmlImplementation Defines the context for a set of XmlDocument objects.
Public class XmlLinkedNode Gets the node immediately preceding or following this node.
Public class XmlNamedNodeMap Represents a collection of nodes that can be accessed by name or index.
Public class XmlNamespaceManager Resolves, adds, and removes namespaces to a collection and provides scope management for these namespaces.
Public class XmlNameTable Table of atomized string objects.
Public class XmlNode Represents a single node in the XML document.
Public class XmlNodeChangedEventArgs Provides data for the NodeChanged, NodeChanging, NodeInserted, NodeInserting, NodeRemoved and NodeRemoving events.
Public class XmlNodeList Represents an ordered collection of nodes.
Public class XmlNodeReader Represents a reader that provides fast, non-cached forward only access to XML data in an XmlNode.
Public class XmlNotation Represents a notation declaration, such as <!NOTATION... >.
Public class XmlParserContext Provides all the context information required by the XmlReader to parse an XML fragment.
Public class XmlProcessingInstruction Represents a processing instruction, which XML defines to keep processor-specific information in the text of the document.
Public class XmlQualifiedName Represents an XML qualified name.
Public class XmlReader Represents a reader that provides fast, non-cached, forward-only access to XML data.
Public class XmlReaderSettings Specifies a set of features to support on the XmlReader object created by the Create method.
Public class XmlResolver Resolves external XML resources named by a Uniform Resource Identifier (URI).
Public class XmlSecureResolver Helps to secure another implementation of XmlResolver by wrapping the XmlResolver object and restricting the resources that the underlying XmlResolver has access to.
Public class XmlSignificantWhitespace Represents white space between markup in a mixed content node or white space within an xml:space= 'preserve' scope. This is also referred to as significant white space.
Public class XmlText Represents the text content of an element or attribute.
Public class XmlTextReader Represents a reader that provides fast, non-cached, forward-only access to XML data.
Public 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.
Public class XmlUrlResolver Resolves external XML resources named by a Uniform Resource Identifier (URI).
Public class XmlValidatingReader Represents a reader that provides document type definition (DTD), XML-Data Reduced (XDR) schema, and XML Schema definition language (XSD) validation.
Public class XmlWhitespace Represents white space in element content.
Public class XmlWriter Represents a writer that provides a fast, non-cached, forward-only means of generating streams or files containing XML data.
Public class XmlWriterSettings Specifies a set of features to support on the XmlWriter object created by the System.Xml.XmlWriter.Create method.
  Interface Description
Public interface IHasXmlNode Enables a class to return an XmlNode from the current context or position.
Public interface IXmlLineInfo Provides an interface to enable a class to return line and position information.
Public interface IXmlNamespaceResolver Provides read-only access to a set of prefix and namespace mappings.
  Delegate Description
Public delegate XmlNodeChangedEventHandler Represents the method that handles NodeChanged, NodeChanging, NodeInserted, NodeInserting, NodeRemoved and NodeRemoving events.
  Enumeration Description
Public enumeration ConformanceLevel Specifies the amount of input or output checking that the created XmlReader and XmlWriter objects perform.
Public enumeration EntityHandling Specifies how the XmlTextReader or XmlValidatingReader handle entities.
Public enumeration Formatting Specifies formatting options for the XmlTextWriter.
Public enumeration NewLineHandling Specifies how to handle line breaks.
Public enumeration ReadState Specifies the state of the reader.
Public enumeration ValidationType Specifies the type of validation to perform.
Public enumeration WhitespaceHandling Specifies how white space is handled.
Public enumeration WriteState Specifies the state of the XmlWriter.
Public enumeration XmlDateTimeSerializationMode Specifies how to treat the time value when converting between string and DateTime.
Public enumeration XmlNamespaceScope Defines the namespace scope.
Public enumeration XmlNodeChangedAction Specifies the type of node change.
Public enumeration XmlNodeOrder Describes the document order of a node compared to a second node.
Public enumeration XmlNodeType Specifies the type of node.
Public enumeration XmlOutputMethod Specifies the method used to serialize the XmlWriter output.
Public enumeration XmlSpace Specifies the current xml:space scope.
Public 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.
