Example

The following XML file contains a QName value, o:name. Note that the prefix "o" is mapped to the namespace http://NamespaceTest.com/Order.

<?xml version="1.0" encoding="utf-8"?>
<p:Purchase xsi:schemaLocation="http://NamespaceTest.com/Purchase Main.xsd"
xmlns:p="http://NamespaceTest.com/Purchase"
xmlns:o="http://NamespaceTest.com/Order"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<p:Order>o:name</p:Order>
</p:Purchase>

A mapping that processes the QName value and gets the namespace URI is illustrated below:

The output of this mapping is http://NamespaceTest.com/Order.
