XML DOM setAttributeNode() Method

Element Object Reference Element Object

Definition and Usage

The setAttributeNode() method adds a new attribute node.

If an attribute with that name already exists in the element, it is replaced by the new one. If the new attribute replaces an existing attribute, the replaced attribute node is returned, otherwise it returns null.

Syntax

elementNode.setAttributeNode(att_node)

Parameter Description
att_node Required. Specifies the attribute node to set

Example

The following code fragment loads "books.xml" into xmlDoc using loadXMLDoc() and adds a "edition" attribute to all <book> elements:

Example

xmlDoc=loadXMLDoc("books.xml");

x=xmlDoc.getElementsByTagName('book');
var newatt;

for (i=0;i<x.length;i++)
{
newatt=xmlDoc.createAttribute("edition");
newatt.value="first";
x[i].setAttributeNode(newatt);
}

//Output all "edition" attribute values
for (i=0;i<x.length;i++)
{
document.write("Edition: ");
document.write(x[i].getAttribute("edition"));
document.write("
");
}

Output:

Edition: first
Edition: first
Edition: first
Edition: first
