Webmaster in a Nutshell, Second Edition

Name

<xsl:if>

Synopsis

<xsl:if test=" pattern " >...</xsl:if>

Description

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 which elements should be selected. The test attribute takes a standard pattern matching string. For example:

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

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