Hello --
Using Saxon 10.3 and XSLT 3.0 (from inside oXygen 23), can I pass a function
as
a parameter to transform()?
<xsl:sequence select="
transform(map {
'stylesheet-location': 'tidy.xsl',
'source-node': $tableMerge,
'stylesheet-params': map {
QName('', 'defaultLang'): $defaultLang,
QName('', 'overrideStringMap'): $overrideStringMap,
QName('', 'lang2key2autotextMap'): $lang2key2autotextMap,
QName('local','getString') : local:getString(xs:string,xs:string)
}
})?output" />
is syntactically acceptable.
yes, but you aren't passing a function, you are passing the result of calling
local:getString with parameters child::xs:string and child::xs:string. Unless
you have any child elements called xs:string, which is unlikely, the actual
parameter values are empty sequences, which is probably why the function is
complaining.
To pass the function itself, rather than the result of a function call, use
local:getString#2.

Inside tidy.xsl,
<xsl:param as="xs:string" name="defaultLang" />
<xsl:param as="map(*)" name="overrideStringMap" />
<xsl:param as="map(*)" name="lang2key2autotextMap" />
<xsl:param as="function(xs:string,xs:string) as xs:string"
name="local:getString" />
is syntactically acceptable (though oXygen complains about the actual
function calls and not being able to find the function).
If I run the transform, though, I get:
Engine name: Saxon-EE 10.3 (External)
Severity: error
Description: An empty sequence is not allowed as the first argument of
local:getString()
with a location that tells me the transform call parameter map is where the
error happens.
Is there a way to do this? I can of course duplicate the function definition
but that seems improper.
Thanks!
