XSLT, 2nd Edition

Name

[2.0] QName()

This is a constructor function that allows you to create a new QName.

Syntax

xs:QName QName($paramURI as xs:string?, $paramQName as xs:string)

Inputs

Two xs:strings. The first string is the namespace URI of the QName, and the second is the string value of the QName. If the second string contains a colon (:), the substring before the colon is the namespace prefix of the QName and the substring after the colon is the local name. For example, if the second string is auth:author, the namespace prefix is auth and the local name is author.

The namespace URI string can be a zero-length string or the empty sequence, meaning this QName does not belong to a namespace. In this case, the XSLT processor raises an error if the second string contains a colon. (In other words, you can’t have a namespace prefix if you don’t have a namespace URI.)

Output

An xs:QName value.

Defined in

XQuery 1.0 and XPath 2.0 Functions and Operators section 11.1, “Additional Constructor Functions for QNames.”

Example

Here is a stylesheet that creates several QNames, and then uses various functions to print the details of those QNames:

<?xml version="1.0"?>
