http://nagoya.apache.org/bugzilla/show_bug.cgi?id=6255 Xalan 2.2 mishandles result tree fragment Summary: Xalan 2.2 mishandles result tree fragment Product: XalanJ2 Version: 2.2.0 Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Major Priority: Other Component: Xalan AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Xalan is incorrectly processing a result tree fragment in a recursive template. I am using the following stylesheet (notice the number 3 at the end of the line marked "NOTICE THIS NUMBER"). ---------------- BEGIN STYLESHEET --------------------- <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0"> <xsl:template name="total-numbers"> <xsl:param name="list"/>3<!-- NOTICE THIS NUMBER --> <xsl:variable name="wlist" select="concat(normalize-space($list), ' ')"/> <xsl:choose> <xsl:when test="$wlist!=' '"> <xsl:variable name="first" select="substring-before($wlist, ' ')"/> <xsl:variable name="rest" select="substring-after($wlist, ' ')"/> <xsl:variable name="total"> <xsl:call-template name="total-numbers"> <xsl:with-param name="list" select="$rest"/> </xsl:call-template> </xsl:variable> <xsl:value-of select="number($first) + number($total)"/> </xsl:when> <xsl:otherwise>0</xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template match="/"> <xsl:call-template name="total-numbers"> <xsl:with-param name="list" select="."/> </xsl:call-template> </xsl:template> </xsl:stylesheet> ---------------- END STYLESHEET --------------------- If I use the following input, ---------------- BEGIN INPUT --------------------- <numbers>12 34.5 18.2 -35</numbers> ---------------- END INPUT --------------------- The stylesheet should get output like this: ---------------- BEGIN OUTPUT --------------------- <?xml version="1.0" encoding="utf-8"?>3 NaN ---------------- END OUTPUT --------------------- Instead, the stylesheet output is ---------------- BEGIN OUTPUT --------------------- <?xml version="1.0" encoding="UTF-8"?> 3 15 ---------------- END OUTPUT --------------------- This stylesheet came from Michael Kay's book XSLT Programmer's Reference (page 616 of the second edition), and Michael himself verified that this output from Xalan is incorrect.
