[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] RE: How to use multiple xsl:import
 Thanx Michael and Dimitre. I understand that using mode will help me control
the way the processor chooses a template. Michael already pointed that out
(both here and in his book) and you clarified it.
Maybe I stated the question wrong. Actually we're not referring to the
import precedence. We're trying to find a way to name the imported
stylesheets, and apply them **anywhere** we choose in the web page. For
that, there's no functionality in xsl:import, AFAIK. Since xsl:import
doesn't provide this functionality (it is only allowed as a top element, and
it lacks a name or mode attribute), it means we simply cannot use the
approach my collegue had in mind.
But there's another approach. Back in March 2002 I ported a clasical ASP
aplication to using modular approach, using the xsl:include approach. That
would be a better solution, although we'll loose the import precedence
functionality. Following is the mother template where six includes are
called.
<?xml version='1.0' ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ms="urn:schemas-microsoft-com:xslt" version="1.0">
<xsl:output method="html" indent="yes" omit-xml-declaration="yes"
encoding="Windows-1252" />
<xsl:include href="nace6inc1.xsl" />
<xsl:include href="nace6inc2.xsl" />
<xsl:include href="nace6inc3sub1.xsl" />
<xsl:include href="nace6inc3sub2.xsl" />
<xsl:include href="nace6inc3sub3.xsl" />
<xsl:include href="nace6inc4.xsl" />
<xsl:template match="/">
<xsl:apply-templates select="root" />
</xsl:template>
<xsl:template name="root" match="root">
<html>
<head>
<title>E L N O R T E - nota</title>
<link href="img/StyleSheet.css"
type="text/css" rel="STYLESHEET" />
</head>
<body vlink="#000080" alink="#000080" link="#000080"
bgcolor="#ffffff" leftmargin="0" topmargin="0" marginheight="?0?"
marginwidth="?0?">
<!-- Header Terra -->
<xsl:call-template name="headerTerra" />
<!-- Header Elnorte -->
<xsl:call-template name="headerElnorte" />
<table cellspacing="0" cellpadding="0" width="760" border="0">
<tbody>
<tr>
<!-- Parte Izquierda - Navegacion-->
<xsl:call-template name="navbarElnorte" />
<!-- Parte Central -->
<xsl:call-template name="centralElnorte" />
<!-- Parte Derecha -Herramientas-->
<xsl:call-template name="herrElnorte" />
</tr>
</tbody>
</table>
<!-- Parte Derecha -Herramientas-->
<xsl:call-template name="footerElnorte" />
</body>
</html>
</xsl:template>
</xsl:stylesheet>
Thanx again for the help, I appreciate it a lot!
Cheers,

This makes perfect sense. Let's take an example:
If the imported stylesheet contains a template, which matches an element
named "foo" and the importing stylesheet contains a template matching
node(), at the instruction:
<xsl:apply-templates select="foo"/>
the template from the importing stylesheet will always be selected over the
one from the imported stylesheet as the former has a higher import
precedence.
The only way to ensure that the wanted template from the imported stylesheet
will be selected is to specify it with a unique mode and change the
xsl:apply-templates to:
<xsl:apply-templates select="foo" mode="fooprefix:fooMode"/>
where fooprefix is bound to a unique namespace-uri
Often the author of a stylesheet that will be imported doesn't know what
stylesheets will be importing it. The only sound protection from a template
with higher imort precedence being selected instead of owr own is to provide
it with unique mode.
In FXSL there is a general convention that referenced templates (whose
template references are passed as parameters to other
templates/functions) must have:
mode="f:FXSL"
where "f" is bound to "http://www.sf.net/fxsl"
The templates that are passed such parameters initiate the referenced
templates using:
<xsl:apply-templates mode="f:FXSL"/>
Of course, this is incompatible with the idea of xsl:apply-imports and, it
turns out, the idea of xsl:apply-imports is not a bulletproof one.
See for example: "Reliance on import precedence considered dangerous "

Hope this helped.
