pc:if

note

This article is about the pc:if Blend directive.

pc:if​

The <pc:if> directive introduces script sections that execute only if a given condition applies.

Syntax

<pc:if test="*xpath >> boolean*">
  <pc:then>
    *conditional-content*
  </pc:then>
  <pc:else>
    *conditional-content*
  </pc:else>
</pc:if>

The value of the required test attribute evaluates to a boolean. If it evaluates to true() according to the rules of the xslutil:test() Blend function, the content of the required <pc:then> child element is processed. If it evaluates to false(), the content of the optional <pc:else> element is processed if it exists.

If you omit the <pc:else> element, you can write the construct in a more compressed format by using pc:if-then.

Examples

The element <PrintThis/> is written to standard output in:

<pc:if test="1=1">
  <pc:then> <PrintThis/> </pc:then>
  <pc:else> <PrintThat/> </pc:else>
</pc:if>

The element <PrintThat/> is written to standard output in:

<pc:if test="1=2">
  <pc:then> <PrintThis/> </pc:then>
  <pc:else> <PrintThat/> </pc:else>
</pc:if>
