Syntax
public class Element : Node, IParentNode, 
	IElementTraversal, IChildNode

The Element type exposes the following members.

Properties
  NameDescription
Public propertyAttributes
A NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise.
(Overrides NodeAttributes.)
Public propertyBaseURI
The absolute base URI of this node or null if the implementation wasn't able to obtain an absolute URI.
(Inherited from Node.)
Public propertyChildElementCount
Returns the current number of element nodes that are children of this element. 0 if this element has no child nodes that are of nodeType 1.
Public propertyChildNodes
A NodeList that contains all children of this node. If there are no children, this is a NodeList containing no nodes..
(Inherited from Node.)
Public propertyChildren
Returns the child elements of current element.
Public propertyClassList
Returns a live DOMTokenList which contains tokens received from parsing the "class" attribute.
Public propertyClassName
The class attribute of the element. This attribute has been renamed due to conflicts with the "class" keyword exposed by many languages. See the class attribute definition in HTML 4.01.
Public propertyFirstChild
The first child of this node. If there is no such node, this returns null.
(Inherited from Node.)
Public propertyFirstElementChild
Returns the first child element node of this element. null if this element has no child elements.
Public propertyId
The element's identifier. See the id attribute definition in HTML 4.01.
Public propertyInnerHTML
Returns a fragment of HTML or XML that represents the element's contents. Can be set, to replace the contents of the element with nodes parsed from the given string.
Public propertyLastChild
The last child of this node. If there is no such node, this returns null.
(Inherited from Node.)
Public propertyLastElementChild
Returns the last child element node of this element. null if this element has no child elements.
Public propertyLocalName
Returns the local part of the qualified name of this node. For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as Document.createElement(), this is always null.
(Overrides NodeLocalName.)
Public propertyNamespaceURI
The namespace URI of this node, or null if it is unspecified.
(Overrides NodeNamespaceURI.)
Public propertyNextElementSibling
Returns the next sibling element node of this element. null if this element has no element sibling nodes that come after this one in the document tree.
Public propertyNextSibling
The node immediately following this node. If there is no such node, this returns null.
(Inherited from Node.)
Public propertyNodeName
The name of this node, depending on its type.
(Overrides NodeNodeName.)
Public propertyNodeType
A code representing the type of the underlying object.
(Overrides NodeNodeType.)
Public propertyNodeValue
The value of this node, depending on its type.
(Inherited from Node.)
Public propertyOuterHTML
Returns a fragment of HTML or XML that represents the element and its contents. Can be set, to replace the element with nodes parsed from the given string.
Public propertyOwnerDocument
The Document object associated with this node. This is also the Document object used to create new nodes. When this node is a Document or a DocumentType which is not used with any Document yet, this is null.
(Inherited from Node.)
Public propertyParentElement
Gets the parent Element of this node.
(Inherited from Node.)
Public propertyParentNode
The parent of this node. All nodes, except Attr, Document, DocumentFragment, Entity, and Notation may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, this is null.
(Inherited from Node.)
Public propertyPrefix
The namespace prefix of this node, or null if it is unspecified. When it is defined to be null, setting it has no effect
(Overrides NodePrefix.)
Public propertyPreviousElementSibling
Returns the previous sibling element node of this element. null if this element has no element sibling nodes that come before this one in the document tree.
Public propertyPreviousSibling
The node immediately preceding this node. If there is no such node, this returns null.
(Inherited from Node.)
Public propertySchemaTypeInfo
The type information associated with this element.
Public propertyShadowRoot
Returns shadowRoot stored on this element or null if it's closed.
Public propertyTagName
The name of the element.
Public propertyTextContent
This attribute returns the text content of this node and its descendants. When it is defined to be null, setting it has no effect. On setting, any possible children this node may have are removed and, if it the new string is not empty or null, replaced by a single Text node containing the string this attribute is set to.
(Overrides NodeTextContent.)

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
(Inherited from EventTarget.)
Protected methodDispose(Boolean)
Releases unmanaged and - optionally - managed resources.
(Overrides NodeDispose(Boolean).)
Public methodEquals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
Protected methodFinalize
Finalizes an instance of the Node class.
(Inherited from Node.)

Retrieves an attribute value by local name and namespace URI.
Public methodGetElementsByClassName
Returns a live NodeList object containing all the elements in the document that have all the classes specified in argument. http://www.w3.org/TR/dom/
Public methodGetElementsByTagName
Returns a NodeList of all descendant Elements with a given tag name, in document order.
Public methodGetElementsByTagNameNS
Returns a NodeList of all the descendant Elements with a given local name and namespace URI in document order.
Public methodGetHashCode
Serves as a hash function for a particular type.
(Inherited from Object.)
Public methodGetType
Gets the type of the current instance.
(Inherited from Object.)
Public methodHasAttribute
Returns true when an attribute with a given name is specified on this element or has a default value, false otherwise.

(Inherited from Node.)
Public methodInsertBefore
Inserts the node before the existing child node child. If child is null, insert node at the end of the list of children. If child is a DocumentFragment object, all of its children are inserted, in the same order, before child. If the child is already in the tree, it is first removed.
(Inherited from Node.)
Public methodIsDefaultNamespace
This method checks if the specified namespaceURI is the default namespace or not.
(Inherited from Node.)
Public methodIsEqualNode
Tests whether two nodes are equal. This method tests for equality of nodes, not sameness (i.e., whether the two nodes are references to the same object) which can be tested with Node.isSameNode(). All nodes that are the same will also be equal, though the reverse may not be true.
(Inherited from Node.)
Public methodIsSameNode
Returns whether this node is the same node as the given one. This method provides a way to determine whether two Node references returned by the implementation reference the same object. When two Node references are references to the same object, even if through a proxy, the references may be used completely interchangeably, such that all attributes have the same values and calling the same DOM method on either reference always has exactly the same effect.
(Inherited from Node.)
Public methodLookupNamespaceURI
Look up the namespace URI associated to the given prefix, starting from this node.
(Inherited from Node.)
Public methodLookupPrefix
Look up the prefix associated to the given namespace URI, starting from this node. The default namespace declarations are ignored by this method. See Namespace Prefix Lookup for details on the algorithm used by this method.
(Inherited from Node.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodNormalize
Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a "normal" form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes. This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer [XPointer] lookups) that depend on a particular document tree structure are to be used. If the parameter "normalize-characters" of the DOMConfiguration object attached to the Node.ownerDocument is true, this method will also fully normalize the characters of the Text nodes.
(Inherited from Node.)

Public methodQuerySelectorAll
Returns a NodeList of all the Elements in document, which match selector
Public methodRemove

(Inherited from Node.)
Public methodRemoveEventListener(String, IEventListener)
This method allows the removal of event listeners from the event target. If an IEventListener is removed from an EventTarget while it is processing an event, it will not be triggered by the current actions. Event Listeners can never be invoked after being removed.
(Inherited from EventTarget.)
Public methodRemoveEventListener(String, DOMEventHandler, Boolean)
This method allows the removal of event listeners from the event target. If an IEventListener is removed from an EventTarget while it is processing an event, it will not be triggered by the current actions. Event Listeners can never be invoked after being removed.
(Inherited from EventTarget.)
Public methodRemoveEventListener(String, IEventListener, Boolean)
This method allows the removal of event listeners from the event target. If an IEventListener is removed from an EventTarget while it is processing an event, it will not be triggered by the current actions. Event Listeners can never be invoked after being removed.
(Inherited from EventTarget.)
Public methodReplaceChild
Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node. If newChild is a DocumentFragment object, oldChild is replaced by all of the DocumentFragment children, which are inserted in the same order. If the newChild is already in the tree, it is first removed.
(Inherited from Node.)
Public methodSetAttribute
Adds a new attribute. If an attribute with that name is already present in the element, its value is changed to be that of the value parameter
Public methodSetAttributeNode
Adds a new attribute node. If an attribute with that name (nodeName) is already present in the element, it is replaced by the new one.
Public methodSetAttributeNodeNS
Adds a new attribute. If an attribute with that local name and that namespace URI is already present in the element, it is replaced by the new one.
