Methods

Name Description
AddEventListener(string, IEventListener) This method allows the registration of event listeners on the event target.
AddEventListener(string, DOMEventHandler, bool) This method allows the registration of event listeners on the event target.
AddEventListener(string, IEventListener, bool) This method allows the registration of event listeners on the event target.
AppendChild(Node) Adds the node newChild to the end of the list of children of this node. If the newChild is already in the tree, it is first removed.
CloneNode() Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent (parentNode is null) and no user data.
CloneNode(bool) Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent (parentNode is null) and no user data.
CreateAttribute(string) Creates an Attr of the given name.
CreateAttributeNS(string, string) Creates an attribute of the given qualified name and namespace URI.
CreateCDATASection(string) Creates a CDATASection node whose value is the specified string.
CreateComment(string) Creates a Comment node given the specified string.
CreateDocumentFragment() Creates an empty DocumentFragment object.
CreateDocumentType(string, string, string, string) Creates a DocumentType node.
CreateElement(string) Creates an element of the type specified. Note that the instance returned implements the Element interface, so attributes can be specified directly on the returned object.
CreateElementNS(string, string) Creates an element of the given qualified name and namespace URI.
CreateEntityReference(string) Creates an EntityReference object. In addition, if the referenced entity is known, the child list of the EntityReference node is made the same as that of the corresponding Entity node.
CreateEvent(string) Creates an Event of a type supported by the implementation.
CreateExpression(string, IXPathNSResolver) Creates a parsed XPath expression with resolved namespaces. This is useful when an expression will be reused in an application since it makes it possible to compile the expression string into a more efficient internal form and preresolve all namespace prefixes which occur within the expression.
CreateNodeIterator(Node) Create a new NodeIterator over the subtree rooted at the specified node.
CreateNodeIterator(Node, long) Create a new NodeIterator over the subtree rooted at the specified node.
CreateNodeIterator(Node, long, INodeFilter) Create a new NodeIterator over the subtree rooted at the specified node.
CreateNSResolver(Node) Adapts any DOM node to resolve namespaces so that an XPath expression can be easily evaluated relative to the context of the node where it appeared within the document. This adapter works like the DOM Level 3 method lookupNamespaceURI on nodes in resolving the namespaceURI from a given prefix using the current information available in the node’s hierarchy at the time lookupNamespaceURI is called, also correctly resolving the implicit xml prefix.
CreateProcessingInstruction(string, string) Creates a ProcessingInstruction node given the specified name and data strings.
CreateTextNode(string) Creates a Text node given the specified string.
CreateTreeWalker(Node) Create a new TreeWalker over the subtree rooted at the specified node.
CreateTreeWalker(Node, long) Create a new TreeWalker over the subtree rooted at the specified node.
CreateTreeWalker(Node, long, INodeFilter) Create a new TreeWalker over the subtree rooted at the specified node.
DispatchEvent(Event) This method allows the dispatch of events into the implementations event model.
Dispose() Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
Evaluate(string, Node, IXPathNSResolver, XPathResultType, object) Evaluates an XPath expression string and returns a result of the specified type if possible.
GetElementById(string) Returns the Element that has an ID attribute with the given value. If no such element exists, this returns null. If more than one element has an ID attribute with that value, what is returned is undefined.
GetElementsByClassName(string) 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/
GetElementsByTagName(string) Returns a NodeList of all the Elements in document order with a given tag name and are contained in the document.
GetElementsByTagNameNS(string, string) Returns a NodeList of all the Elements with a given local name and namespace URI in document order.
virtual GetPlatformType() This method is used to retrieve ECMAScript object Type.
virtual HasAttributes() Returns whether this node (if it is an element) has any attributes
HasChildNodes() Returns whether this node has any children.
ImportNode(Node, bool) Imports a node from another document to this document, without altering or removing the source node from the original document; this method creates a new copy of the source node.
InsertBefore(Node, Node) 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.
IsDefaultNamespace(string) This method checks if the specified namespaceURI is the default namespace or not.
IsEqualNode(Node) 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.
IsSameNode(Node) 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.
LookupNamespaceURI(string) Look up the namespace URI associated to the given prefix, starting from this node.
LookupPrefix(string) 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.
Navigate(RequestMessage) Loads the document based on specified request object, replacing the previous content.
Navigate(string) Loads the document at the specified Uniform Resource Locator (URL) into the current instance, replacing the previous content.
Navigate(Url) Loads the document at the specified Uniform Resource Locator (URL) into the current instance, replacing the previous content.
Navigate(Stream, string) Loads the document from specified content and using baseUri to resolve relative resources, replacing the previous content. Document loading starts from the current position in the stream.
Navigate(Stream, Url) Loads the document from specified content and using baseUri to resolve relative resources, replacing the previous content. Document loading starts from the current position in the stream.
Navigate(string, string) Loads the document from specified content and using baseUri to resolve relative resources, replacing the previous content.
Navigate(string, Url) Loads the document from specified content and using baseUri to resolve relative resources, replacing the previous content.
Normalize() 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.
QuerySelector(string) Returns the first Element in document, which match selector
QuerySelectorAll(string) Returns a NodeList of all the Elements in document, which match selector
RemoveChild(Node) Removes the child node indicated by oldChild from the list of children, and returns it.
RemoveEventListener(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.
RemoveEventListener(string, DOMEventHandler, bool) 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.
RemoveEventListener(string, IEventListener, bool) 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.
virtual RenderTo(IDevice) This method is used to render the contents of the current document to a specified graphical device.
ReplaceChild(Node, Node) 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.
override ToString() Returns a String that represents this instance.
Write(params string[]) Write a string of text to a document stream opened by open(). Note that the function will produce a document which is not necessarily driven by a DTD and therefore might be produce an invalid result in the context of the document.
WriteLn(params string[]) Write a string of text followed by a newline character to a document stream opened by open(). Note that the function will produce a document which is not necessarily driven by a DTD and therefore might be produce an invalid result in the context of the document
