Details

The element typically contains a number of xsl:when elements, each with a separate test condition. The first xsl:when element whose condition matches the current element in the source document is expanded, the others are ignored. If none of the conditions is satisfied, the xsl:otherwise child element, if any, is expanded.

The test condition in the xsl:when element is a boolean expression. The full syntax of expressions is outlined in XPath Expression Syntax.

Examples

<xsl:choose> <xsl:when test="@cat='F'">Fiction</xsl:when> <xsl:when test="@cat='C'">Crime</xsl:when> <xsl:when test="@cat='R'">Reference</xsl:when> <xsl:otherwise>General</xsl:otherwise> </xsl:choose>
