Consider this stylesheet that tests three != 0 expressions. You can run it against any XML file, as all it does it output messages to indicate expression results.
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns="http://www.w3.org/1999/xhtml"; version="1.0"> <xsl:template match="/"> <xsl:variable name="text" select="'A'"/> <xsl:variable name="node">B</xsl:variable> <xsl:choose> <xsl:when test="$text != 0"> <xsl:message>text value A is not equal to zero</xsl:message> </xsl:when> <xsl:otherwise> <xsl:message>text value A is *not* not equal to zero!</xsl:message> </xsl:otherwise> </xsl:choose> <xsl:choose> <xsl:when test="$node != 0"> <xsl:message>node value B is not equal to zero</xsl:message> </xsl:when> <xsl:otherwise> <xsl:message>node value B is *not* not equal to zero!</xsl:message> </xsl:otherwise> </xsl:choose> <xsl:choose> <xsl:when test="string($node) != 0"> <xsl:message>node string value B is not equal to zero</xsl:message> </xsl:when> <xsl:otherwise> <xsl:message>node string value B is *not* not equal to zero!</xsl:message> </xsl:otherwise> </xsl:choose> </xsl:template> </xsl:stylesheet> When I run it with xsltproc from libxslt version 10114CVS1011 on Windows XP, I get: text value A is not equal to zero node value B is *not* not equal to zero! node string value B is not equal to zero Does anyone else think the middle test produces the wrong result? My understanding is that in equality expressions, if one operand is a number then the other is converted to a number. Converting a node means first converting it to a string and then converting that string to a number. So that node conversion should yield NaN, which should not be equal to zero. Am I missing something, or should I file a bug report?
