[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] controller stylsheet. performance, best practices ques
 Here is the script, questions to follow: <?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <!-- import templates implementing dynamic content -->
<xsl:import href="xsl-inc_finder.xsl" />
<xsl:import href="xsl-inc_subjects.xsl" />
<xsl:import href="xsl-inc_requirements.xsl" />
<xsl:import href="xsl-inc_listing.xsl" />
<xsl:import href="xsl-inc_login.xsl" /> <!-- set context used by the controller -->
<xsl:param name="op" select="'<?php echo @$_GET["op"]; ?>'" /> <!-- BEGIN MAIN PAGE TEMPLATE-->
<xsl:template match="/">
<!-- blah blah blah. masses of literal content goes here -->
<!-- CALLS TO THE MAIN CONTENT BEGIN HERE -->
<xsl:choose>
<xsl:when test="$op = 'finder'">
<xsl:call-template name="finderPage" />
</xsl:when>
<xsl:when test="$op = 'subjects'">
<xsl:call-template name="subjectsPage" />
</xsl:when>
<xsl:when test="$op = 'login'">
<xsl:call-template name="loginPage" />
</xsl:when>
</xsl:choose>
<!-- CALLS TO THE MAIN CONTENT END HERE -->
<!-- blah blah blah. masses of literal content goes here -->
</xsl:template>
<!-- END MAIN PAGE TEMPLATE--></xsl:stylesheet> Functionally, this appoach seems to work well for me. My questions is: Is taking this sort of approach prone to big performance problems? I can see that in many cases, most of the templates imported at the top of the style sheet will not even be used. They can't be included on the fly because they need to be top-level (can't be nested inside IF or CHOOSE).* Any other observations about the merits of this approach appreciated. cheers. * I could probably use PHP code to include it on the fly, but I want to avoid doing so because I've made a rule for myself not to use server-side code embedded in the stylesheet. I've done so in the param of this example for purposes of clarity, normally I would send them to the processor directly from the PHP function call.
