http://nagoya.apache.org/bugzilla/show_bug.cgi?id=24583 muenchian grouping + sorting with strange effects Summary: muenchian grouping + sorting with strange effects Product: XalanJ2 Version: 2.5 Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: Other Component: org.apache.xalan.transformer AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] I try to transform the Cocoon Gump descriptor available at http://cvs.apache.org/viewcvs.cgi/cocoon-2.1/gump.xml (simplified version will be attached) with a stylesheet to a property file as http://cvs.apache.org/viewcvs.cgi/cocoon-2.1/blocks.properties. In the stylesheet I group the Cocoon blocks (<project name="cocoon-block-xyz">) depending on their @status. The problem is in the following template: The stylesheet: <xsl:key name="status" match="project[starts-with(@name, 'cocoon-block-')]" use="@status"/> <xsl:template match="/module"> <xsl:apply-templates select="project[starts-with(@name, 'cocoon-block-')] [count(. | key('status', @status)[1]) = 1]" mode="group"/> </xsl:template> <xsl:template match="project" mode="group"> -------- <xsl:apply-templates select="key('status', @status)"> <xsl:sort select="@name"/> </xsl:apply-templates> </xsl:template> <xsl:template match="project"> <xsl:value-of select="@name"/> <xsl:text> </xsl:text> </xsl:template> There are 3 different groups ('stable', 'unstable', 'deprecated'), which should result in 3 lines of -------- as long as the elements of one group are not sorted. If the above xsl:sort is in use, there are more lines. One further line is added if the grouping element (i.e. the one returned by key('status', @status)[1]) is not the first one after sorting. With the gump.xml as it is, you get 5 lines. If you rename the first project element to cocoon-block-aaaa, you will only get 4 lines. This happens with Xalan 2.5.2 and seems to be a regression bug.
