Can one _generate_ namespace nodes?
I've got a situation where I'm using namespace aliasing. It's working fine, but the output (using Xalan, at least) is a bit ugly; the serializer doesn't realize that the new prefix binding is required until it gets down to the aliased nodes, and generates the binding there. Since these are scattered throughout the document, that means a lot of namespace declaration nodes. I'd prefer to declare the new prefix once, at the top of the generated document. But there doesn't seem to be a way to express that. There's no <xsl:namespace-node> to go with <xsl:attribute>, and <xsl:attribute> is explicitly forbidden to generate namespace declarations. (Actually, the way it's forbidden doesn't work now that namespaces have been redefined to be namespace-aware rather than being hardcoded to the xmlns: prefix, but that's a separate matter.) I could generate a dummy attribute with the correct prefix and namespace at the top level, and let that imply a declaration -- but that could break validation of the generated document, and sometimes it's explicitly forbidden. (If I'm generating a stylesheet element, I'd have to create an attribute in the same namespace as xsl: -- but those are reserved for XSL's use, and there isn't one which is officially legal on an <xsl:stylesheet> element.) I say again, this is an attempt to fix a purely cosmetic problem... but it really feels like there ought to be a solution. If anyone *does* know of an official and reliable way to generate a namespace declaration into a document at a specific point, I'd appreciate the tip! If not... well, the article goes out as "it's ugly but it works." ______________________________________ Joe Kesselman, IBM Next-Generation Web Technologies: XML, XSL and more.
