Name

<xsl:choose>

Synopsis

<xsl:choose>
   ...
</xsl:choose>

The xsl:choose element, in conjunction with the elements xsl:when and xsl:otherwise, offers the ability to perform multiple condition tests. For example:

<xsl:template match="chapter/title">
   <xsl:choose>
      <xsl:when test="[position()=1]">
          Start Here:
      </xsl:when>
      <xsl:otherwise>
          Then Read:
       </xsl:otherwise>
   </xsl:choose>
   <xsl:apply-templates/>
</xsl:template>

This example matches against each of the qualifying title elements, but it must test each title element to determine how to format it. Here, formatting depends on whether the element is first. The string Start Here: is applied before the first title element, and the string Then Read: is placed before the others.
