Predefined Constants

DOMNode::DOCUMENT_POSITION_DISCONNECTED: Set when the other node and reference node are not in the same tree.
DOMNode::DOCUMENT_POSITION_PRECEDING: Set when the other node precedes the reference node.
DOMNode::DOCUMENT_POSITION_FOLLOWING: Set when the other node follows the reference node.
DOMNode::DOCUMENT_POSITION_CONTAINS: Set when the other node is an ancestor of the reference node.
DOMNode::DOCUMENT_POSITION_CONTAINED_BY: Set when the other node is a descendant of the reference node.
DOMNode::DOCUMENT_POSITION_IMPLEMENTATION_SPECIFIC: Set when the result depends on implementation-specific behaviour and may not be portable. This may happen with disconnected nodes or with attribute nodes.

Properties

nodeName: Returns the most accurate name for the current node type
nodeValue: The value of this node, depending on its type. Contrary to the W3C specification, the node value of DOMElement nodes is equal to DOMNode::textContent instead of null.
nodeType: Gets the type of the node. One of the predefined XML_*_NODE constants
parentNode: The parent of this node. If there is no such node, this returns null.
parentElement: The parent element of this element. If there is no such element, this returns null.
childNodes: A DOMNodeList that contains all children of this node. If there are no children, this is an empty DOMNodeList.
firstChild: The first child of this node. If there is no such node, this returns null.
lastChild: The last child of this node. If there is no such node, this returns null.
previousSibling: The node immediately preceding this node. If there is no such node, this returns null.
nextSibling: The node immediately following this node. If there is no such node, this returns null.
attributes: A DOMNamedNodeMap containing the attributes of this node (if it is a DOMElement) or null otherwise.
isConnected: Whether the node is connected to a document
ownerDocument: The DOMDocument object associated with this node, or null if this node is a DOMDocument
namespaceURI: The namespace URI of this node, or null if it is unspecified.
prefix: The namespace prefix of this node.
localName: Returns the local part of the qualified name of this node.
baseURI: The absolute base URI of this node or null if the implementation wasn't able to obtain an absolute URI.
textContent: The text content of this node and its descendants.

Changelog

Version	Description
8.3.0	Properties DOMNode::$parentElement, and DOMNode::$isConnected have been added.
8.0.0	The unimplemented methods DOMNode::compareDocumentPosition, DOMNode::isEqualNode, DOMNode::getFeature, DOMNode::setUserData and DOMNode::getUserData have been removed.

Notes

Note:
The DOM extension uses UTF-8 encoding. Use mb_convert_encoding, UConverter::transcode, or iconv to handle other encodings.
