XML Pocket Reference, Second Edition

Name

<xsl:if>

Synopsis

<xsl:if
   test=”expression“>
   ...
</xsl:if>

You can use the xsl:if conditional to select a specific element while inside a template. The xsl:if element uses the test attribute to determine whether to include the contents of an element. The test attribute takes an expression that tests for a specific element or attribute. For example:

<xsl:template match="chapter/title">
   <xsl:apply-templates/>
   <xsl:if test="not([last()])">, </xsl:if>
</xsl:template>

This template matches each qualifying title element but inserts commas only after those that are not the last title element. The result is a standard comma-separated list.
