This is a bug report against the XSLT 3.0 development branch of Xalan.
I am still trying to use the function fold-left with some XSLT defined function
but run into a strange error "XPTY0004 Function call argument at position 1 for
function
{http://example.com/mf}
identity(), doesn't match the declared parameter type node()" followed by a
java.lang.NullPointerException.
{code:xml}
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="3.0"
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:mf="http://example.com/mf";
exclude-result-prefixes="xs mf">
<xsl:output method="xml" indent="yes"/>
<xsl:function name="mf:identity" as="node()">
<xsl:param name="node" as="node()"/>
<xsl:sequence select="$node"/>
</xsl:function>
<xsl:template match="/">
<xsl:copy>
<xsl:sequence select="fold-left(//*, (), function($a, $n) { ($a,
mf:identity($n)) })"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
{code}
Run that against any XML input and you will get the XPTY0004 for each element
node in the input followed by the NullPointerException.
The code runs with with Saxon HE 12.5 Java as well as SaxonJS so I think it is
clean and proper XSLT 3.
The shown code is a reduced test case whether I can get any node passed from
fold-left to an XSLT defined function, my real use case is using fold-left to
chain calls of the transform function, as I get the same error "XPTY0004 :
Function call argument at position 1 for function
\{http://example.com/mf}transform-node(), doesn't match the declared parameter
type node()" there I hope if the simple test case can be fixed the real use
case also works.
For completeness I tried to attach the real use as well but somehow attaching
currently fails. I will try to attach the file later after I have created the
bug issue.
