Which does raise the question, given two different elements, element A in ns X and Y element A in ns X An element has one, and exactly one, name. That name has a namespace URI and a local part. The namespace part may be null, if there is no prefix and no default namespace in scope. This example has no namespace URI and a local part of "foo": <foo xmlns=""/> The namespace part may be a URI. In both of these examples, the URI is "http://crism.maden.org/consulting/example-namespace" and the local part is "foo": <foo xmlns="http://crism.maden.org/consulting/example-namespace"/> <ex:foo xmlns:ex="http://crism.maden.org/consulting/example-namespace"/> Now, this is getting confused with the namespace declarations in scope. An element only ever has one namespace. But more than one namespace *declaration* may be in scope for that element. In these examples, the element has the namespace http://crism.maden.org/consulting/example-namespace and a local part of "foo", but there are two namespace declarations in scope: <ex:foo xmlns:ex="http://crism.maden.org/consulting/example-namespace" xmlns="http://crism.maden.org/consulting/example-namespace-2"/> <foo xmlns="http://crism.maden.org/consulting/example-namespace" xmlns:ex="http://crism.maden.org/consulting/example-namespace-2"/> These elements are of the same type. In XPath 1.0, you must use a prefix to match an element type with a URI. In XSLT, the way to bind that prefix to a URI is to have namespace declarations in scope in the XML document that is the stylesheet: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ex="http://crism.maden.org/consulting/example-namespace"> <xsl:template match="ex:foo"/> </xsl:stylesheet> That template matches *all* of the foo elements given above, except the first one (which has no namespace URI).
