== The <xsl:if> Element: Conditional Processing==



<source lang="xml">
The xsl:if element tests whether a Boolean condition is true or false.
If it is true, then the content of the xsl:if element is instantiated.
If it is false, then nothing specified inside the xsl:ifelement is added to the result tree.
