[xsl] how to reflect on the namexpaces URIs and prefixes in XSLT?
Date: 2/11/2002 6:41:00 AM
Hi, 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: <xsd:complexType name='foo'/> 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='$root'/> where <xsl:variable name='root' select='/'/> doesn't contain any xmlns:... attributes, at least not at the point of my XSLT execution where I need them. - even if I find those xmlns:... attributes (which I do, sort of, in the root template of the XSLT), how do I query those? I can see the xslns attributes show up when I do <xsl:copy-of select='$root//xsd:schema'/> but as soon as I'm trying to grab them specifically, e.g., using: <xsl:for-each select='$root//xsd:schema/@*'/> 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? thanks, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow@xxxxxxxxxxxxxxx Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
