This is a bug report on the XSLT 3.0 development branch of Xalan.
I have tried to use the newly implemented `except` operator but get a
java.lang.StackOverflowError with a simple test case that runs fine with Saxon
HE 12 Java.
XSLT code:
{code:java}
<?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:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="/*">
<xsl:copy>
<xsl:apply-templates select="* except (foo, bar)"/>
</xsl:copy>
</xsl:template>
<xsl:template match="/">
<xsl:copy>
<xsl:apply-templates/>
<xsl:comment>Run with <xsl:value-of
select="system-property('xsl:vendor')"/> at <xsl:value-of
select="current-dateTime()"/></xsl:comment>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
{code}
XML input sample:
{code:java}
<root>
<foo>foo 1</foo>
<bar>bar 1</bar>
<baz>baz 1</baz>
<foo>foo 2</foo>
<baz>baz 2</baz>
</root>{code}
Result with Xalan:
{noformat}
