I am using XSLT 2 via AltovaXML.
I have a need to look up "key" terms in an external glossary document. The
external document has a default namespace at the root level. The code works
fine like this:
<xsl:param name="GLOSSARY" select="'./working_files/glossary.xml'"/>
<xsl:key name="definitions" match="glossentry" use="term/@key"
xpath-default-namespace="http://www.abcdef.com/hij"/>
<xsl:variable name="glossaryDocument" select="document($GLOSSARY)"/>
...
<xsl:variable name="definition">
<xsl:for-each select="$glossaryDocument">
<xsl:value-of select="key('definitions',
$normalizedText)/definition" xpath-default-namespace="
http://www.abcdef.com/hij"/>
</xsl:for-each>
</xsl:variable>
After testing I decided to replace the "hardcoded" namespace with a "global"
variable. I was surprised to find that this did not work.
<xsl:variable name="glossNS" select="'http://www.abcdef.com/hij'"
as="xs:anyURL"/>
<xsl:key name="definitions" match="glossentry" use="term/@key"
xpath-default-namespace="{$glossNS}"/>
...
<xsl:value-of select="key('definitions',
$normalizedText)/definition" xpath-default-namespace="{$glossNS}"/>
I've check the spec and I can't find anything to make me believe this
shouldn't work but it's entirely possible I may have missed some subtlety.
Can anyone tell me if this a bug or expected behaviour?
Well the XSLT 2.0 specification for values taking an attribute value
template uses a syntax like
xsl:element name = { qname }
(i.e. curly braces are used).
For the xpath-default-namespace the syntax is defined on xsl:stylesheet
without curly braces:
<xsl:stylesheet
id? = id
extension-element-prefixes? = tokens
exclude-result-prefixes? = tokens
version = number
xpath-default-namespace? = uri
so the syntax you want is not supported.
