Re: Templates, Q Names and namespaces
Hi Paul, No reasons to worry -- your stylesheet will work without modifications, as long as the namespace-uri for the different prefixes continues to be the same (in your case "http:myco.com"). You'll continue to access my:elem by specifying m:elem, whatever:elem -- as long as the "m:" and "whatever:" prefixes have been used in a namespace declaration that associates them to the same namespace-uri -- in your case "http:myco.com". The reverse is also true -- you can change the prefixes or use several different prefixes in your source -- as long as they've been associated with the same namespace-uri as the prefix used in your stylesheet, then your stylesheet will continue to access by the same Q-name the nodes with the changed prefixes. You can check this for yourself with a simple stylesheet. This is the correct behaviour of an XSLT processor according to the XSLT/XPath specifications. I've verified that SAXON and MSXML 3 perform exactly in this way. In case the default namespace is re-defined in your source xml document, then it will not be possible from a stylesheet to access by name any un-preffixed elements (in scope of the redefinition) in the source document -- even in the case when the same default namespace redefinition is specified in the stylesheet. Dimitre Novatchev. -------------------------Original message ---------- In an XML document, I might have an element <my:elem xmlns:my="http:myco.com">...</my:elem> In a stylesheet, I can write something like: <xsl:apply-templates select="my:elem"/> <xsl:template match="my:elem">...</xsl:apply-templates> Now, if I apply my stylesheet a new document containing: <m:elem xmlns:m="http:myco.com">...</m:elem> my stylesheet will no longer work. Equally, I could be using a default namespace in the source document. What is the simplest way to make my stylesheet independent of the prefix used for the namespace, while keeping it correctly attached to the namespace URI itself? And are there known XSL implementations where this doesn't work (I know implementations of namespaces in some XSL implementations is rather flaky).
