RE: [xsl] If vs. apply-templates for optional attributes

["Hunsberger, Peter" <Peter dot Hunsberger at stjude dot org>]

I'm doing the same test for many different elements....

I can't see how the named template gains me anything?  It doesn't make the
code any more compact,
and although the call to the named template likely adds no overhead, passing
the parameter might?  Moreover,
the test is still done. 

A smart compiler shouldn't have much more overhead for a modal template than
a named template, or am I missing something?

If you're going to be using this type of test frequently (I'm not sure
whether you meant for the same element a dozen times or for a dozen
elements), you could use a named template with a parameter:

<xsl:template match="testelement">
	<xsl:call-template name="attTest">
	  <xsl:with-param name="node" select="."/>
	</xsl:call-template>
</xsl:template>

<xsl:template name="attTest">
<xsl:param name="node"/>
<xsl:copy>
	<xsl:if test="not($node[@attr])">
		<xsl:attribute name="attr">test</xsl:attribute>
	</xsl:if>
</xsl:copy>
</xsl:template>	

HTH,
John
