Functions
The appendChild()
method of the Node interface adds a node to the end of the list of children of a specified parent node.
The appendData()
method of the CharacterData interface adds the provided data to the end of the node's current data.
The compareDocumentPosition()
method of the Node interface reports the position of its argument node relative to the node on which it is called.
The deleteData()
method of the CharacterData interface removes all or part of the data from this CharacterData
node.
The getRootNode()
method of the Node interface returns the context object's root, which optionally includes the shadow root if it is available.
The hasChildNodes()
method of the Node interface returns a boolean value indicating whether the given Node has child nodes or not.
The insertData()
method of the CharacterData interface inserts the provided data into this CharacterData
node's current data, at the provided offset from the start of the existing data.
The isDefaultNamespace()
method of the Node interface accepts a namespace URI as an argument.

method of the Node interface tests whether two nodes are equal.
The isSameNode()
method of the Node interface is a legacy alias the for the ===
strict equality operator.
The lookupNamespaceURI()
method of the Node interface takes a prefix as parameter and returns the namespace URI associated with it on the given node if found (and null
if not).
The lookupPrefix()
method of the Node interface returns a string containing the prefix for a given namespace URI, if present, and null
if not.
The removeChild()
method of the Node interface removes a child node from the DOM and returns the removed node.
The replaceData()
method of the CharacterData interface removes a certain number of characters of the existing text in a given CharacterData
node and replaces those characters with the text provided.
Replaces node with nodes, while replacing strings in nodes with equivalent Text nodes.
The substringData()
method of the CharacterData interface returns a portion of the existing data, starting at the specified index and extending for a given number of characters afterwards.
