CHAPTER 9: Integrating XML into JavaScript XML Object Reference 255

QName object

This object encapsulates a fully qualified XML name, the combination of a local XML name and its

namespace URI.

QName object constructors

The constructor takes several forms:

new QName ()

new QName (name)

new QName (ns)

new QName (uri, name)

When no arguments are supplies, creates a QName object with an empty local name and no URI.

QName object properties

Namespace object

This object encapsulates the definition of an XML namespace. A namespace associates an XML-name

prefix with a complete URI. The prefix is a string that precedes the local name of an XML element or

attribute and identifies the namespace, while the URI points to the actual location where the definition of

the namespace is found.

For example, this XML definition contains a namespace declaration:

<?xml xmlns:adobe=http://www.adobe.com/test?>

In the corresponding namespace, the prefix is adobe, and the URI is http://www.adobe.com/test.
