key() on xsl:key with literal @use returns too many nodes
---------------------------------------------------------
Key: XALANJ-2399
URL: https://issues.apache.org/jira/browse/XALANJ-2399
Project: XalanJ2
Issue Type: Bug
Affects Versions: 2.7
Environment: Windows XP Pro x64; JRE 1.5.0_12
Reporter: Deborah Pickett
Using a literal* string value for @use in an xsl:key causes key() to return too
many nodes in the node-set for that key.
I define a key in a couple of places (same stylesheet or different, seems to
behave the same):
<xsl:key name="name" match="foo" use="'string'"/>
<xsl:key name="name" match="bar" use="..."/>
<xsl:key name="name" match="baz" use="..."/>
It does not seem to matter what the "..." are.
Calls to key('name', 'string') should give a node-set only of <foo> elements,
but I also get <bar> and <baz> elements, essentially every node that has a
presence in the "name" key.
Calls to key('name', 'never-seen-before-string') return an empty node-set.
* Or, it seems, an expression that can be optimized into a literal. This makes
the bug go away:
<xsl:key name="group" match="[EMAIL PROTECTED] = 'concept']"
use="concat(substring(@type, 1, 1), 'oncept')"/>
but this still has the bug:
<xsl:key name="group" match="[EMAIL PROTECTED] = 'concept']"
use="concat(substring(@type, 1, 0), 'concept')"/>
Small test case follows.

Stylesheet:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
<xsl:key name="group" match="[EMAIL PROTECTED] = 'concept']"
use="'concept'"/>
<xsl:key name="group" match="[EMAIL PROTECTED] = 'task']" use="'task'"/>
<xsl:key name="group" match="[EMAIL PROTECTED] = 'reference']"
use="'reference'"/>
<xsl:template match="/">
<xsl:apply-templates select="key('group', 'concept')"/>
</xsl:template>
</xsl:stylesheet>
