The Document Object Model (DOM) is a programming interface for HTML, XML and SVG documents. It provides a structured representation of the document as a tree. The DOM defines methods that allow access to the tree, so that they can change the document structure, style and content. The DOM provides a representation of the document as a structured group of nodes and objects, possessing various properties and methods. Nodes can also have event handlers attached to them, and once an event is triggered, the event handlers get executed. Essentially, it connects web pages to scripts or programming languages.

The NodeFilter.acceptNode() method returns an unsigned short that will be used to tell if a given Node must be accepted or not by the NodeIterator or TreeWalker iteration algorithm. This method is expected to be written by the user of a NodeFilter. Possible return values are:

The TreeWalker.firstChild() method moves the current Node to the first visible child of the current node, and returns the found child. It also moves the current node to this child. If no such child exists, returns null and the current node is not changed.

API DOM DOM Reference Method TreeWalker

The TreeWalker.lastChild() method moves the current Node to the last visible child of the current node, and returns the found child. It also moves the current node to this child. If no such child exists, returns null and the current node is not changed.

API DOM DOM Reference Method TreeWalker

The TreeWalker.nextNode() method moves the current Node to the next visible node in the document order, and returns the found node. It also moves the current node to this one. If no such node exists, returns null and the current node is not changed.

The TreeWalker.nextSibling() method moves the current Node to its next sibling, if any, and returns the found sibling. I there is no such node, return null and the current node is not changed.
