namespace-uri | NetBeansв„ў IDE Field Guide: Developing Desktop, Web, Enterprise, and Mobile Applications (2nd Edition)

The namespace-uri() function returns a string that represents the URI of the namespace in the expanded name of a node. Typically, this will be a URI used in a namespace declaration, that is, the value of an xmlns or xmlns:* attribute in the source XML.

For example, if you apply this function to the outermost element of an XSLT stylesheet by writing the expression «namespace-uri(document(' ')/*) » , the result will be the string « http://www.w3.org/1999/XSL/Transform » .
