Thank you, Dr. Kay,
This can be simplified to:
<xsl:variable name="vFuns" as="map(xs:string, function(*))"
select="map {
'move' : f:move#0,
'stop' : f:stop#0
}
"
/>
Yes, I know the f:fun#Arity syntax but could never force myself to use
it -- still seems rather "unnatural".
As for:
<xsl:map>
<xsl:map-entry key="'move'" select="f:move#0"/>
<xsl:map-entry key="'stop'" select="f:stop#0"/>
</xsl:map>
this seems of little use as the <xsl:map> instruction has to be
enclosed in the body of an <xsl:variable> -- so isn't it better just
to define the map in the `select` attribute of the variable
declaration?
Also, why use the verbose <xsl:map-entry> as compared to the XPath way
of writing a map-literal? I know that this can be useful in
dynamically creating a map when the number of key-value pairs is
determined at runtime -- but this still isn't the case in this
question.
Cheers,
Dimitre

You can also use XSLT syntax:
<xsl:map>
<xsl:map-entry key="'move'" select="f:move#0"/>
<xsl:map-entry key="'stop'" select="f:stop#0"/>
</xsl:map>

I also like this XSLT/XPath 3 way:
<xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xs="http://www.w3.org/2001/XMLSchema"; xmlns:f="my:f">
<xsl:param name="pFunName" select="'move'" as="xs:string"/>
<xsl:variable name="vFuns" as="map(xs:string, function(*))"
select="map {
'move' : function() as xs:string {f:move()},
'stop' : function() as xs:string {f:stop()}
}
"
/>
<xsl:function name="f:move" as="xs:string">
Move
</xsl:function>
<xsl:function name="f:stop" as="xs:string">
Stop
</xsl:function>
<xsl:template match="/">
<xsl:value-of select="$vFuns('move')(), $vFuns('stop')()"/>
</xsl:template>
</xsl:stylesheet>
In this line of the code:
<xsl:value-of select="$vFuns('move')(), $vFuns('stop')()"/>
we can also pass string variables or expressions that produce string and not
just the literal name of the function.
When this simple example is run (against any XML document -- not used), we
get the expected result:
Move
Stop

Hi Folks,
I have an XSLT variable, $function-to-invoke, that holds the name of an XSLT
function to be invoked. For example, if $function-to-invoke holds the string
"move" then I want my XSLT program to invoke the function with that name,
i.e., invoke f:move(...). Is there a way for XSLT to call a function whose
name isn't known till run-time?
