以上程序会将1.xml解析，并将内容放入数组。

Get the Value of an Attribute

In the DOM, attributes are nodes. Unlike element nodes, attribute nodes have text values.

The way to get the value of an attribute, is to get its text value.

This can be done using the getAttribute() method or using the nodeValue property of the attribute node.

---

Get an Attribute Value - getAttribute()

The getAttribute() method returns an attribute value.

The following code retrieves the text value of the "lang" attribute of the first <title> element:

Example

xmlDoc=loadXMLDoc("books.xml");

txt=xmlDoc.getElementsByTagName("title")[0].getAttribute("lang");
Try it yourself »

Result:  txt = "en"

Example explained:

1. Load "books.xml" into xmlDoc using loadXMLDoc()
2. Set the txt variable to be the value of the "lang" attribute of the first title element node

Loop through all <book> elements and get their "category" attributes: Try it yourself
