Hi,
I currently have some very unwieldy predicates showing up in lots of
xsl:template/@match statements, of the form:
<xsl:template match="
foo[ substring-after(./@format,':') = 'type1' and
namespace-uri-for-prefix(substring-before(./@format,':'),.)
= 'http://example.com/schemas/formats' ]">
which aim to match different <foo> elements based on the @format QName
value, e.g.:
<table xmlns:fmt='http://example.com/schemas/formats'>
<foo format="fmt:type1">2008-09-23</foo>
<foo format="fmt:type2">9/23/08</foo>
</table>
and which do QName expansion so the user can choose the prefix.
I would like to replace the "match" statement with a simplified custom
function of the form:
<xsl:template match="foo[ my:test('type1',.) = true ]">
where my:test is defined as:
<xsl:function name="my:test">
<xsl:param name="fmtcode"/>
<xsl:param name="context"/>
<xsl:choose>
<xsl:when test="substring-after($context/@format,':') = $fmtcode and
namespace-uri-for-prefix(substring-before($context/@format,':'),$context)
= 'http://example.com/schemas/formats' ">
<xsl:value-of select="boolean(1)"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="boolean(0)"/>
</xsl:otherwise>
</xsl:choose>
</xsl:function>
The problem is, this doesn't work with Saxon8B. Would others expect
this to work with different XSLT v2.0 processors? Is there some way to
get this to work with Saxon8B?
Cheers,
Ian
