## XML DOM nodeName Property The `nodeName` property is a standard property of the XML DOM (Document Object Model) used to retrieve the name of a specified node. When applied to an Element node, it returns the tag name of that element. --- ## Definition and Usage The `nodeName` property returns the name of the selected node as a string. Depending on the node type, the value returned by `nodeName` varies: * For **Element** nodes, it returns the tag name (e.g., `"title"`, `"book"`). * For **Attribute** nodes, it returns the attribute name. * For **Text** nodes, it always returns `"#text"`. * For **Document** nodes, it always returns `"#document"`. *Note: In XML DOM, the returned tag name preserves the original casing defined in the XML document. In HTML DOM, the returned tag name is always in uppercase.* --- ## Syntax ```javascript elementNode.nodeName ``` ### Return Value * **Type:** String * **Description:** The name of the node (the tag name for element nodes). --- ## Code Example The following example demonstrates how to load an XML document (`books.xml`) using a helper function `loadXMLDoc()` and retrieve the node name of the first ` Giada De Laurentiis 2005 30.00 ``` ### JavaScript Implementation ```javascript // Load the XML document var xmlDoc = loadXMLDoc("books.xml"); // Get the first
