Subject: Re: [xsl] apply-templates and predicates From: David Carlisle <davidc@xxxxxxxxx> Date: Thu, 28 Apr 2005 15:04:17 +0100 |
<xsl:template match="*"> <xsl:message>unexpected element encountered: <xsl:value-of select="name()" /></xsl:message> </xsl:template> as always, a match template only executes if you apply templates to a matching node. that version makes a warning and doesn't process children. If you want to process children then <xsl:template match="*"> <xsl:message>unexpected element encountered: <xsl:value-of select="name()" /></xsl:message> <xsl:apply-templates/> </xsl:template> I use either form, depending. If I haven't got round to supporting mathml yet I'd rather get one warning for each mathml:math element at the top level of each expression in the document, I don't really want to be told on every character of every expression that I haven't yet supported mathml:mi, so I'd use the first form. In other cases, the second form, processing children is more useful. Other variants: <xsl:template match="*"> <xsl:message>unexpected element encountered: <xsl:value-of select="name()" /></xsl:message> <div class="error"> <span>unexpected element encountered: <xsl:value-of select="name()" /></span> <xsl:apply-templates/> </div> </xsl:template> so that you not only get a warning, but also a big red block of stuff in the output.
