Declaring the msxsl: Namespace Prefix
Before using the msxsl:node-set()
function in an XSLT style sheet, you must declare the msxml:
namespace prefix. Most often this is done in the root <xml:stylesheet>
element of the style sheet, as shown below:
XSLT File (msxsldecl.xsl)
<?xml version='1.0'?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt"> <xsl:template match="text()"/> </xsl:stylesheet>
As with other namespace declarations, the prefix (such as msxsl:
) is not important. Only the namespace URI (that is, the value of the xmlns
attribute) is important. To use the Microsoft implementation of the node-set()
extension function, that value must be "urn:schemas-microsoft-com:xslt"
. For example, you could use either of the following two namespace declarations, as long as all references to the node-set()
function appear as ms:node-set()
or xyz:node-set()
, respectively.
xmlns:ms="urn:schemas-microsoft-com:xslt"
xmlns:xyz="urn:schemas-microsoft-com:xslt"
Throughout this topic, we have used the msxsl:
prefix.
Note The Uniform Resource Identifier (URI) for using Microsoft extensions to core W3C technologies takes the form of a Uniform Resource Name (URN), such as urn:schemas-microsoft-com:xslt. This is an accepted alternative to a Uniform Resource Locator (URL), such as http://www.w3.org/1999/XSL/Transform.
Also note that declaring themsxsl:
namespace gives your style sheet access not only to themsxsl:node-set()
function, but also to other Microsoft extensions, such as the<msxsl:script>
element.
