xsl:if

Conditionally instantiates the contained template body.

Format

The XSLT processor evaluates the expression and converts the result to a Boolean value. If the result is true, the XSLT processor instantiates template_body. If the result is false, the xsl:if element has no effect.

Example

This following example formats a group of names as a comma-separated list:

<xsl:template match="namelist/name"> 
  <xsl:value-of select="." /> 
  <xsl:if test="not(position()=last())">, </xsl:if> 
</xsl:template>
