bug in xsl:when

Jacob Miles Sun, 27 Feb 2005 12:55:18 -0800

Hi. I got a NullPointerException when I accidentally used 'match' instead of 'test' in an xsl:when. Thought I'd pass it along.

The xslt:

<xsl:template match="*">
                <xsl:choose>                                      
                        <xsl:when test="html">
                                <xsl:call-template name="html"/>
                        </xsl:when>
                        <xsl:when match="head">
                                <xsl:call-template name="head"/>
                        </xsl:when>
                        <xsl:when test="body">
                                <xsl:call-template name="body"/>
                        </xsl:when>
                        <xsl:otherwise>
                                <xsl:copy-of select="."/>
                        </xsl:otherwise>
                </xsl:choose>
        </xsl:template>
