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="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( $DocumentCode , 6 , 1 )"/> <xsl:variable name="FirstPass" as="document-node()">
<xsl:document>
<xsl:copy-of select="Test"/>
</xsl:document>
</xsl:variable> <xsl:template match="Test">
<xsl:result-document href="test20.html" format="OutHTML">
<xsl:apply-templates select="$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> <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? tia, ...sam
