XML Attribute

specifies a single property for the element, using a

name/value

pair. An XML-element can have

one or more

attributes

<a href = "http://www.applications.ge/">Applications.ge</a>

In the example

href

is the

attribute name

and

http://www.applications.ge

is the

attribute value

... XML attribute names (unlike HTML) are case sensitive. Which means that

HREF

and

href

are considered two different XML attributes

<?xml version="1.0"?>
<student>
    <a href="http://www.applications.ge/" hreF="HTTP://applications.ge/">Applications.ge</a>
</student>

Several different values for the same attribute is not allowed. An attribute name must not appear more than once in the same tags:

<?xml version="1.0"?>
<student>
    <a href="http://www.applications.ge/" href="HTTP://applications.ge/">Applications.ge</a>
</student>

The following error will appear on the browser

error on line 3 at column 73: Attribute 
href
 redefined

Attribute names must always be defined without quotation marks, whereas attribute values must always appear in single or double quotation marks

<?xml version="1.0"?>
<student>
    <a "href"="http://www.applications.ge/">Applications.ge</a>
</student>

The following error will appear:

error on line 3 at column 8: error parsing 
attribute name
 

Attribute values must always be in quotation marks (single

'

or double

"

quotes)

<?xml version="1.0"?>
<student>
    <a href=http://www.applications.ge/>Applications.ge</a>
</student>

This incorrect syntax will generate the following error:

error on line 3 at column 13: AttValue: " or ' expected
