XSL processor

As you can see, the value passed in through JavaScript is correctly output to the HTML result. If you use

parameters in this way, you can make style sheets more extensible by incorporating different behaviors

based on parameters.

Another advanced feature of the XSL processor is the capability to set a mode of operation. In XSLT,

it’s possible to define a mode for a template. When a

mode

is defined, the template isn’t run unless

<xsl:apply-templates />

is specifically called with its

mode

attribute. For example:

<xsl:stylesheet version=”1.0” xmlns:xsl=”http://www.w3.org/1999/XSL/Transform”>

<xsl:output method=”html” />

<xsl:param name=”message” />

<xsl:template match=”/”>

<html>

<head>

<title>Employees</title>

</head>

<body>

<ul>

<xsl:apply-templates select=”*” />

</ul>

Message: <xsl:value-of select=”$message” />

</body>

</html>

</xsl:template>

<xsl:template match=”employee”>

<li><xsl:value-of select=”name” />, <xsl:value-of select=”@title”

/></li>

</xsl:template>

<xsl:template match=”employee” mode=”position-first”>

<li><xsl:value-of select=”@title” />, <xsl:value-of select=”name”

/></li>

</xsl:template>

</xsl:stylesheet>

This style sheet defines a template with its

mode

attribute set to

“position-first”

(note that you can

name a mode whatever you want; there are no predefined modes). Inside of this template, the employee’s

position is output first, and the employee name is output second. In order to use this template, the

<xsl:apply-templates/>

element must have its

mode

set

to “position-first”

as well. If you use

this style sheet, it has the same output as the previous one, displaying the employee name first and the

position second. If, however, you use this style sheet and set the mode to

“position-first”

using

JavaScript, it outputs the employee’s position first:

oProcessor.input = oXmlDom;

oProcessor.addParameter(“message”, “Hello World!”);

oProcessor.setStartMode(“position-first”);

oProcessor.transform();
