-------------------------------------
Summary: document-node() matches/selects more than document nodes
Key: XALANJ-2818
URL: https://issues.apache.org/jira/browse/XALANJ-2818
Project: XalanJ2
Issue Type: Bug
Security Level: No security risk; visible to anyone (Ordinary problems in
Xalan projects. Anybody can view the issue.)
Components: Xalan, Xalan-CmdLine, XPath
Affects Versions: The Latest Development Code
Environment: Java 8, Windows 11
Reporter: Martin Honnen
Attachments: document-node-test1.xsl, document-node-test2.xsl,
sample2.xml
This is a bug report against the XSLT 3.0 development branch of Xalan.
I find that document-node() matches/selects a lot more than just document nodes.
Here are two test cases:
{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";
xmlns:map="http://www.w3.org/2005/xpath-functions/map";
xmlns:array="http://www.w3.org/2005/xpath-functions/array";
exclude-result-prefixes="#all">
<xsl:output method="text"/>
<xsl:template match="/">
<xsl:value-of select="count(descendant-or-self::document-node())"/>
</xsl:template>
</xsl:stylesheet>
{code}
which should output 1 for any XML input but seems to output the number of nodes
in the whole input document and
{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";
xmlns:map="http://www.w3.org/2005/xpath-functions/map";
xmlns:array="http://www.w3.org/2005/xpath-functions/array";
exclude-result-prefixes="#all">
<xsl:output method="text"/>
<xsl:param name="count" as="xs:integer" select="1"/>
<xsl:template match="document-node()">
<xsl:param name="count" select="$count"/>
<xsl:text>Matching document-node() </xsl:text>
<xsl:value-of select="$count"/>
<xsl:text> </xsl:text>
<xsl:apply-templates>
<xsl:with-param name="count" select="$count + 1"/>
</xsl:apply-templates>
</xsl:template>
</xsl:stylesheet>
{code}
which should process the single document nodes but with Xalan processes lots of
nodes e.g. outputs
{noformat}
Matching document-node() 1
Matching document-node() 2
Matching document-node() 3
Matching document-node() 3
Matching document-node() 4

Matching document-node() 5

Input sample is e.g.
{code:java}
<root>
<div>
<para>This is a test.</para>
<para>This is a test.</para>
</div>
<div>
<para>This is a second test.</para>
<para>This is a second test.</para>
</div>
</root>{code}
