Subject: Re: [xsl] apply-templates and predicates From: David Carlisle <davidc@xxxxxxxxx> Date: Wed, 27 Apr 2005 17:33:03 +0100 |
If you filter on the apply-templates it is unlikely that the default template match will ever get invoked. If you have templates that match all the elemnts that appear in your source the default template will not be used, otherwise it will be. That happens in either style. Actually it depoends a bit what you mean by default template. Do you mean the in built default, in my stylesheets that is rarely caused because I usually start off stylesheets by going <xsl:template match="*"> <xsl:message> Unexpected element <xsl:value-of select="name()"/> </xsl:message> </xsl:template> Or by default do you mean any template with a * wildcard whether explictly in the stylesheet, as above, or the built in one? and am looking at ways of making the XSLT as managable as possible. I find that handling different match patterns to handle the various special cases is a lot more manageable than using filters on the select. I mainly use the filter on select idiom if the filter involves a global parameter to the stylesheet, as XSLT1 restrictions disallowing variables in match patterns means that is often the best way. In XSLT2 this restriction will be dropped so I'd expect to use the match pattern version even more often.
