key function not working on trees that have been created by using exsl:node-set function on result tree fragment
----------------------------------------------------------------------------------------------------------------

Key: XALANJ-2504
URL: https://issues.apache.org/jira/browse/XALANJ-2504
Project: XalanJ2
Issue Type: Bug
Security Level: No security risk; visible to anyone (Ordinary problems in Xalan projects. Anybody can view the issue.)
Components: XSLTC
Affects Versions: 2.7.1
Environment: Windows XP Professional SP 3, Sun Java JRE 6 (1.6)
Reporter: Martin Honnen

The key function is not working properly on trees that have been created by converting a result tree fragment to a node-set with the extension function exsl:node-set. Instead of returning the nodes with the passed in key value it looks as if an empty node-set is returned.

Details:

With the XSLT stylesheet being

<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:exsl="http://exslt.org/common"
exclude-result-prefixes="exsl"
version="1.0">

<xsl:output indent="yes"/>

<xsl:key name="k1" match="foo" use="bar"/>

<xsl:template match="/">
<html lang="en">
<head>
<title>Test case</title>
</head>
<body>
<h1>Test case</h1>
<xsl:variable name="rtf1">
<foo><bar>1</bar></foo>
<foo><bar>1</bar></foo>
<foo><bar>2</bar></foo>
</xsl:variable>
<p>The count should be 2.
<xsl:for-each select="exsl:node-set($rtf1)">
<xsl:variable name="c" select="count(key('k1', '1'))"/>
Count returned is <xsl:value-of select="$c"/>.
<xsl:choose>
<xsl:when test="$c = 2">
<xsl:text>Test succeeded.</xsl:text>
</xsl:when>
<xsl:otherwise><xsl:text>Test failed.</xsl:text></xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</p>
</body>
</html>
</xsl:template>

</xsl:stylesheet>

the output (when run against any XML input) with Xalan interpreter of Saxon is as follows:

<html lang="en">
<head>
<META http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Test case</title>
</head>
<body>
<h1>Test case</h1>
<p>The count should be 2.

Count returned is 2.
Test succeeded.</p>
</body>
</html>

so the number of nodes returned by the call key('k1', '1') is 2 as it should be.

When I run with Xalan XSLTC then the output is

<html lang="en">
<head>
<META http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Test case</title>
</head>
<body>
<h1>Test case</h1>
<p>The count should be 2.

Count returned is 0.
Test failed.</p>
</body>
</html>

so the number of nodes returned by the call key('k1', '1') is 0 which is a bug.

This bug is quite a problem any time you want to use keys (e.g. with Muenchian grouping) on temporary results created by converting a result tree fragment to a node-set with the help of exsl:node-set.
