XmlNode Class

Definition

Represents a single node in the XML document.

Remarks

This class implements the W3C Document Object Model (DOM) Level 1 Core and the Core DOM Level 2. The DOM is an in-memory (cache) tree representation of an XML document. XmlNode is the base class in the .NET implementation of the DOM. It supports XPath selections and provides editing capabilities. The XmlDocument class extends XmlNode and represents an XML document. You can use XmlDocument to load and save XML data. It also includes methods for node creation. See XML Document Object Model (DOM) for more information.

Importante

Exceptions raised as a result of using the XmlNode class, such as the XmlException class may contain sensitive information that should not be exposed in untrusted scenarios. Exceptions should be properly handled so that this sensitive information is not exposed in untrusted scenarios.

Properties

Attributes

Gets an XmlAttributeCollection containing the attributes of this node.

BaseURI

Gets the base URI of the current node.

Gets or sets the concatenated values of the node and all its child nodes.

InnerXml

Gets or sets the markup representing only the child nodes of this node.

IsReadOnly

Item[String]

Gets the first child element with the specified Name.

LastChild

NamespaceURI

Gets the namespace URI of this node.

NextSibling

Gets the node immediately following this node.

NodeType

OuterXml

Gets the markup containing this node and all its child nodes.

OwnerDocument

Gets the XmlDocument to which this node belongs.

ParentNode

Gets the parent of this node (for nodes that can have parents).

Prefix

Gets or sets the namespace prefix of this node.

PreviousSibling

Methods

AppendChild(XmlNode)

Adds the specified node to the end of the list of child nodes, of this node.

Clone()

Creates a duplicate of this node.

CloneNode(Boolean)

Creates a duplicate of the node, when overridden in a derived class.

CreateNavigator()

Creates an XPathNavigator for navigating this object.

Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object)
GetEnumerator()

Gets an enumerator that iterates through the child nodes in the current node.

GetHashCode()

Serves as the default hash function.

(Inherited from Object)
GetNamespaceOfPrefix(String)

Looks up the closest xmlns declaration for the given prefix that is in scope for the current node and returns the namespace URI in the declaration.

GetPrefixOfNamespace(String)

Looks up the closest xmlns declaration for the given namespace URI that is in scope for the current node and returns the prefix defined in that declaration.

GetType()

Gets the Type of the current instance.

(Inherited from Object)
InsertAfter(XmlNode, XmlNode)

Inserts the specified node immediately after the specified reference node.

InsertBefore(XmlNode, XmlNode)

Inserts the specified node immediately before the specified reference node.

MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
Normalize()

Puts all XmlText nodes in the full depth of the sub-tree underneath this XmlNode into a "normal" form where only markup (that is, tags, comments, processing instructions, CDATA sections, and entity references) separates XmlText nodes, that is, there are no adjacent XmlText nodes.

PrependChild(XmlNode)

Adds the specified node to the beginning of the list of child nodes for this node.

RemoveAll()

Removes all the child nodes and/or attributes of the current node.

RemoveChild(XmlNode)

Removes specified child node.

ReplaceChild(XmlNode, XmlNode)

Replaces the child node oldChild with newChild node.

SelectNodes(String, XmlNamespaceManager)

Selects a list of nodes matching the XPath expression. Any prefixes found in the XPath expression are resolved using the supplied XmlNamespaceManager.

SelectNodes(String)

Selects a list of nodes matching the XPath expression.

SelectSingleNode(String, XmlNamespaceManager)

Selects the first XmlNode that matches the XPath expression. Any prefixes found in the XPath expression are resolved using the supplied XmlNamespaceManager.

SelectSingleNode(String)

Selects the first XmlNode that matches the XPath expression.

Supports(String, String)

Tests if the DOM implementation implements a specific feature.

ToString()

Returns a string that represents the current object.

(Inherited from Object)
WriteContentTo(XmlWriter)

Saves all the child nodes of the node to the specified XmlWriter, when overridden in a derived class.

WriteTo(XmlWriter)

Saves the current node to the specified XmlWriter, when overridden in a derived class.
