I have found inconsistent behavior when using current() in the use
attribute of a key element.
Shouldn't these
<xsl:key name="keyUsingCurrent" match="color" use="current()/@id"/>
<xsl:key name="keyWithoutCurrent" match="color" use="@id"/>
produce the same set of keys?With this XML
<t>
<color id="b">blue</color>
<color id="r">red</color>
</t>and this XSLT <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="text" indent="no"/> <xsl:key name="keyUsingCurrent" match="color" use="current()/@id"/>
<xsl:key name="keyWithoutCurrent" match="color" use="@id"/> <xsl:template match="/">
(1):<xsl:value-of select="key('keyUsingCurrent', 'b')"/>
(2):<xsl:value-of select="key('keyUsingCurrent', 'r')"/> (1):<xsl:value-of select="key('keyWithoutCurrent', 'b')"/>
(2):<xsl:value-of select="key('keyWithoutCurrent', 'r')"/>
</xsl:template></xsl:stylesheet> Xalan, Saxon and the XSLT processors in Firefox and Internet Explorer return (1):blue
(2):red (1):blue
(2):redwhich I think is correct; xsltproc and the XSLT processors in Chrome and Safari return (1):
(2): (1):blue
(2):redwhich I think is incorrect. Is my understanding of current() inside @use correct? Am I witnessing a bug in code that xsltproc, Chrome and Safari share? If so, to whom would I report such a bug? Would doing so make any difference? I need current() to work inside @use, so that I can have an attribute such as use="../tagUsage[@render=current()/@xml:id]/@gi". See http://stackoverflow.com/questions/13984167/create-xsl-key-by-joining-elements. If this is a bug, is there a workaround? Thanks for any help. -- JPM John P. McCaskey, mailbox@xxxxxxxxxxxxxxxx
