XML Namespaces

This lesson is part of XML · All levels

Summary

XML namespaces prevent name collisions when two different libraries use the same element name, e.g. <harga> of the store module and tax module. Namespace is declared via the xmlns attribute and usually uses a URI as a unique identifier. With prefixes like xmlns:tp, each element indicates which namespace it uses.

Key points

Namespace prevents intermodal or interstandard name conflicts
Default declaration using the xmlns attribute
Namespace prefixed with xmlns:prefix="URI"
URI is used as a unique identifier, not to be opened as a web page
The prefix on the element indicates the namespace of the element's origin
