A module with the XQuery/XPath Core Library Functions
namespace-uri
namespace-uri($arg as node()?) xs:anyURI
Returns the namespace URI of the xs:QName of $arg.
If the argument is omitted, it defaults to the context node (.). The behavior of the function if the argument is omitted is exactly the same as if the context item had been passed as the argument.
The following errors may be raised: if the context item is undefined [err:XPDY0002]XP; if the context item is not a node [err:XPTY0004]XP.
If $arg is neither an element nor an attribute node, or if it is an element or attribute node whose expanded-QName (as determined by the dm:node-name accessor in the Section 5.11 node-name AccessorDM) is in no namespace, then the function returns the xs:anyURI corresponding to the zero-length string.
