You can encode a switch statement with xsl:choose

Each case is represented with an xsl:when element.

xsl:when works just like xsl:if

The default case can be specified by xsl:otherwise

Syntax:

<xsl:choose>
<xsl:when test="...">...</xsl:when>
<xsl:when test="...">...</xsl:when>
<xsl:otherwise>...</xsl:otherwise>
</xsl:choose>
