## DOM Element: removeAttributeNode() Method
The `removeAttributeNode()` method removes a specified attribute node from an element.
This method is part of the W3C DOM Core standard and is supported in both XML DOM and HTML DOM environments.
---
## Definition and Usage
The `removeAttributeNode()` method removes an `Attr` (attribute) node from an element.
### Key Characteristics:
* **Return Value:** It returns the removed `Attr` node object. This allows you to inspect its properties (such as `nodeName` or `nodeValue`) or reuse it elsewhere in your document.
* **DTD Default Values:** If the removed attribute has a default value defined in a Document Type Definition (DTD), a new attribute node is automatically created with the default value, namespace URI, local name, and prefix (if applicable).
* **Difference from `removeAttribute()`:** While `removeAttribute(name)` takes a string representing the attribute's name, `removeAttributeNode(node)` requires the actual `Attr` node object as its argument.
---
## Syntax
```javascript
elementNode.removeAttributeNode(attributeNode)
```
### Parameters
| Parameter | Type | Description |
| :--- | :--- | :--- |
| `attributeNode` | `Attr` | **Required.** The attribute node object that you want to remove. |
### Return Value
| Type | Description |
| :--- | :--- |
| `Attr` | The removed attribute node object. |
### Exceptions
* **`DOMException` (NOT_FOUND_ERR):** Thrown if the specified `attributeNode` is not an attribute of the element.

## Code Examples
### Example 1: Removing All Attributes from XML Elements
The following example loads an XML file ("books.xml") and removes all attribute nodes from every `` element, printing out the name and value of each removed attribute.
```javascript
// Load the XML document
const xmlDoc = loadXMLDoc("books.xml");
// Get all elements
const books = xmlDoc.getElementsByTagName('book');
for (let i = 0; i < books.length; i++) {
// Loop through and remove all attributes of the current book element
while (books.attributes.length > 0) {
// Get the first attribute node
const attrNode = books.attributes;
// Remove the attribute node and store the returned node
const removedAttr = books.removeAttributeNode(attrNode);
// Output the details of the removed attribute
document.write("Removed: " + removedAttr.nodeName + ": " + removedAttr.nodeValue + "
"); } } ``` ### Example 2: HTML DOM Usage You can also use this method in standard HTML web pages. Here is how to find and remove a specific attribute node from an HTML element: ```html
