Hello again,
Still debugging the upgrade to XSLT 2.0. This one took some time to create a reduced stylesheet that still reproduced the error. The XML instance file (probably irrelevant) is the same as my last post:
Using SaxonB-8.9j, I get the following error:
with the following XSLT:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output name="OutHTML" method="html" encoding="windows-1252"/>
<xsl:param name="DocumentCode" select=" 'abc11111' "/>
<xsl:param name="Flag1" select="boolean( true() or false() )"/> <!-- force to true -->
<xsl:param name="Flag2" select="boolean( number( substring( $DocumentCode , 6 , 1 ) ) )"/>
<xsl:param name="Flag3" select="substring( $DocumentCode , 6 , 1 )"/>
<xsl:template name="SomeNamedTemplate">
<xsl:variable name="SomeVariable1">
<xsl:choose>
<xsl:when test="$Flag3 = '1' and //SomeElement[not(ancestor::Foo)][not(contains(string(Bar),'$'))]">true</xsl:when>
<xsl:when test="$Flag3 != '1' and //SomeElement[not(contains(string(Foo),'$'))]">true</xsl:when>
</xsl:choose>
</xsl:variable>
<xsl:value-of select="$SomeVariable1"/>
</xsl:template>
</xsl:stylesheet>
*However*, when I try to debug by adding an xsl:message within xsl:variable name="SomeVariable1", the error goes away (?!). i.e. with this mod:
<xsl:variable name="SomeVariable1">
<!-- the xsl:message instruction below makes error go away! -->
<xsl:message>Flag3: <xsl:value-of select="$Flag3"/>, Cond1: <xsl:value-of select="//SomeElement[not(ancestor::Foo)][not(contains(string(Bar),'$'))]"/>, Cond2: <xsl:value-of select="//SomeElement[not(contains(string(Foo),'$'))]"/></xsl:message>
<xsl:choose>
<xsl:when test="$Flag3 = '1' and //SomeElement[not(ancestor::Foo)][not(contains(string(Bar),'$'))]">true</xsl:when>
<xsl:when test="$Flag3 != '1' and //SomeElement[not(contains(string(Foo),'$'))]">true</xsl:when>
</xsl:choose>
</xsl:variable>
I now get the following in the output, and the transformation continues to the end without any errors:
<<Flag3: 1, Cond1: , Cond2: >>
Any thoughts on what is going on here?

Hello again,
Still debugging the upgrade to XSLT 2.0. This one took some time to create a reduced stylesheet that still reproduced the error. The XML instance file (probably irrelevant) is the same as my last post:
<?xml version="1.0" encoding="UTF-8"?> <Test>"Hello" ≠ "World"</Test>
Using SaxonB-8.9j, I get the following error:
<<Error on line 42 of file:/C:/Test/Saxon/Test20.xsl: XPTY0004: Cast does not allow an empty sequence Transformation failed: Run-time errors were reported>>
with the following XSLT:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output name="OutHTML" method="html" encoding="windows-1252"/>

<xsl:param name="Flag1" select="boolean( true() or false() )"/> <!-- force to true -->
<xsl:param name="Flag2" select="boolean( number( substring( $DocumentCode , 6 , 1 ) ) )"/>
<xsl:param name="Flag3" select="substring( $DocumentCode , 6 , 1 )"/>
<xsl:variable name="FirstPass" as="document-node()">
<xsl:document>
<xsl:copy-of select="Test"/>
</xsl:document>
</xsl:variable> <xsl:template match="Test">
<xsl:result-document href="test20.html" format="OutHTML">
<xsl:apply-templates select="$FirstPass" mode="SomeMode"/>
</xsl:result-document>
</xsl:template> <xsl:template match="Test" mode="SomeMode">
<html>
<head>
<title>test</title>
</head>
<body>
<p><xsl:call-template name="SomeNamedTemplate"/></p>
</body>
</html>
</xsl:template><xsl:template name="SomeNamedTemplate">
<xsl:variable name="SomeVariable1">
<xsl:choose>
<xsl:when test="$Flag3 = '1' and //SomeElement[not(ancestor::Foo)][not(contains(string(Bar),'$'))]">true</xsl:when>
<xsl:when test="$Flag3 != '1' and //SomeElement[not(contains(string(Foo),'$'))]">true</xsl:when>
</xsl:choose>
</xsl:variable>
