Templates à la mode
The XSLT <xsl:template> element has a mode attribute
that lets you process the same set of nodes several times. For
example, we might want to process <h1> elements one way when we generate
a table of contents, and another way when we process the document as a
whole. We could use the mode
attribute to define different templates for different purposes:
<xsl:template match="h1" mode="build-toc"> <!-- Template to process the <h1> element for table of contents --> </xsl:template> <xsl:template match="h1" mode="process-text"> <!-- Template to process the <h1> element along with the rest --> <!-- of the document --> </xsl:template>
We can then start applying templates with the mode attribute:
<xsl:template match="/">
<html>
<body>
<h1>Table of Contents</h1>
<ul>
<xsl:apply-templates select="h1" mode="build-toc"/>
</ul>
<xsl:apply-templates select="*" mode="process-text"/>
</body>
</html>
</xsl:template>This style of coding makes maintenance much easier; if the table
of contents isn’t generated correctly, the templates with mode="build-toc" are the obvious place to
start debugging. (We discuss the mode attribute in more detail in the section
New values for the mode attribute” later in this
chapter.)
