how to reflect on the namexpaces URIs and prefixes in
I am working on a XSLT dealing with XML Schemas. I generate certain Schema thingies, like complexType and simpleType and other elements. Within those, I need to deal properly with the XML Schema "targetNamespace". For instance, if the ancestor schema node of the input document has this
<xsd:schema xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:v3dt='urn::hl7.org/v3dt' targetNamespace='urn::hl7.org/v3dt'>
now if I generate a xsd:complexType definition for a type called 'foo' I will generate:
if I refer to such types defined in the schema, I have to do something like this:
<xsd:element name='thing' type='v3dt:foo' />
Now the questions:
- how do I query for the active namespace prefix declarations in the input document?
Apparently (in saxon at least) the document that I can see with <copy-of select='$root'/> where <xsl:variable name='root' select='/'/> doesn't contain any xmlns:... attributes, at least not at the point of my XSLT execution where I need them.
- even if I find those xmlns:... attributes (which I do, sort of, in the root template of the XSLT), how do I query those? I can see the xslns attributes show up when I do
but as soon as I'm trying to grab them specifically, e.g., using:
I'm not seeing any of the xmlns ones. They only show up if anything is actually using the namespace in the output, but how do I know what namespace prefix the xsd:schema/@targetNamespace is bound to?
It sounds like XSLT is making namespace prefix declarations a special thing (which is O.K.) but it doesn't provide any special mechanisms by which one could dynamically work with the namespaces used by an input document. Are there any workarounds?
