XML DOM - Objek Node
Objek Node
Objek Node mewakili satu node di pohon dokumen.
Sebuah node dapat berupa node elemen, node atribut, node teks, atau jenis node lainnya yang dijelaskan dalam bab Node Types .
Perhatikan bahwa sementara semua objek mewarisi properti / metode Node untuk berurusan dengan orang tua dan anak-anak, tidak semua objek dapat memiliki orang tua atau anak-anak. Misalnya, node Teks mungkin tidak memiliki anak, dan menambahkan anak ke node tersebut akan menghasilkan kesalahan DOM.

| nodeType | Returns the type of a node |
| nodeValue | Sets or returns the value of a node, depending on its type |
| ownerDocument | Returns the root element (document object) for a node |

Metode Objek Node
| Method | Description |
|---|---|
| appendChild() | Appends a new child node to the end of the list of children of a node |
| cloneNode() | Clones a node |
| compareDocumentPosition() | Compares the placement of two nodes in the DOM hierarchy (document) |
| getFeature(feature,version) | Returns a DOM object which implements the specialized APIs of the specified feature and version |
| getUserData(key) | Returns the object associated to a key on a this node. The object must first have been set to this node by calling setUserData with the same key |
| hasAttributes() | Returns true if the specified node has any attributes, otherwise false |
| hasChildNodes() | Returns true if the specified node has any child nodes, otherwise false |
| insertBefore() | Inserts a new child node before an existing child node |
| isDefaultNamespace(URI) | Returns whether the specified namespaceURI is the default |
| isEqualNode() | Tests whether two nodes are equal |
| isSameNode() | Tests whether the two nodes are the same node |
| lookupNamespaceURI() | Returns the namespace URI associated with a given prefix |
| lookupPrefix() | Returns the prefix associated with a given namespace URI |
| normalize() | Puts all Text nodes underneath a 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 |
| removeChild() | Removes a specified child node from the current node |
| replaceChild() | Replaces a child node with a new node |
| setUserData(key,data,handler) | Associates an object to a key on a node |
