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_xxx_NODE constants
parentNode: The parent of this node. If there is no such node, 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.
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, or null if it is unspecified.
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.
