xsl:choose
Syntax
<xsl:choose>
<xsl:when test="boolean-expression">
...
</xsl:when>
<xsl:otherwise>
...
</xsl:otherwise>
</xsl:call-template>Description
Evaluate multiple conditional tests, and execute
instructions for the first test that evaluates to TRUE or execute
an optional default set of instructions if all tests evaluate to FALSE.
The <xsl:choose> instruction contains
one or more <xsl:when> elements, each
of which tests a Boolean expression. If the test evaluates to TRUE,
the XSLT processor executes the instructions
in the <xsl:when> element, and ignores
all subsequent <xsl:when> elements.
The XSLT processor processes only the instructions contained in the
first <xsl:when> element whose test attribute evaluates to TRUE. If none of the <xsl:when> elements’ test attributes evaluate to TRUE, the content of the optional <xsl:otherwise> element, if one is present, is processed.
