XML DOM setAttribute() Method

Complete Element Object Reference

Definition and Usage

The setAttribute() method adds a new attribute.

If an attribute with that name already exists in the element, its value is changed to be that of the value parameter

Syntax

elementNode.setAttribute(name,value)

Example

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

xmlDoc=loadXMLDoc("books.xml");

x=xmlDoc.getElementsByTagName("book");

for(i=0;i<x.length;i++)
{
x.item(i).setAttribute("edition","first");
}

//Output book title and edition value
x=xmlDoc.getElementsByTagName("title");
for (i=0;i<x.length;i++)
{
document.write(x[i].childNodes[0].nodeValue);
document.write(" - Edition: ");
document.write(x[i].parentNode.getAttribute('edition'));
document.write("<br />");
}

Output:

Everyday Italian - Edition: FIRST
Harry Potter - Edition: FIRST
XQuery Kick Start - Edition: FIRST
Learning XML - Edition: FIRST
