<xsl:if>

The <xsl:if> element contains a test attribute and a template. If the test evaluates to true, the template is processed. In this it is similar to an if statement in other languages. To achieve the functionality of an if-then-else statement, however, use the <xsl:choose> element with one <xsl:when> and one <xsl:otherwise> children.
