Using the latest Xalan XSLT 3.0 development branch, I get a
NullPointerException when trying to use an XSLT key function call on the right
side of the XPath 3.1 map operator "!".
Expected result: the code should not give any errors but output e.g.
{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<set>
<problem>
<question>Which lots have red cars?</question>
<answer>
<lot id="L"/>
<lot id="L"/>
<lot id="N"/>
</answer>
</problem>
</set>
{code}
The XSLT code:
{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";
exclude-result-prefixes="xs">
<xsl:output method="xml" indent="yes"/>
<xsl:key name="car-by-color" match="cars/car" use="@color"/>
<xsl:key name="lot-for-car" match="lot" use="car/@vin"/>
<xsl:template match="lot">
<lot id="{@id}"/>
</xsl:template>
<xsl:template match="/">
<set>
<problem>
<question>Which lots have red cars?</question>
<answer>
<xsl:apply-templates select="(key('car-by-color', 'red') !
key('lot-for-car', @vin))"/>
</answer>
</problem>
</set>
</xsl:template>
</xsl:stylesheet>
{code}
XML input:
{code:xml}
<dir>
<cars>
<car vin="101" color="red"/>
<car vin="102" color="green"/>
<car vin="103" color="red"/>
<car vin="104" color="red"/>
</cars>
<lots>
<lot id="L">
<car vin="101"/>
<car vin="103"/>
</lot>
<lot id="M">
<car vin="102"/>
</lot>
<lot id="N">
<car vin="104"/>
</lot>
</lots>
</dir>
{code}
Full error output:
{code:java}
