XSLT Tutorial

XSLT Elements: xsl:if

xsl:if

<xsl:if test=boolean expression>
    template body
</xsl:if>

• The xsl:if element allows an instruction to be run if it meets a criteria, like the if statement in most languages, except that there is no else statement.  The criteria for entering the if statement is based on a test.
  
  
• Criteria: The criteria is evaluated by a test expression, which returns a true boolean for the following:
  
    - if the expression returns a node-set, there must be a node in it, 
    - if the expression returns a string, the string cannot be empty, and
    - if the expression returns a number, it must not equal zero (0).
  
  
• There is no else instruction
