<if variable></if>

Provided by module: Tags: RXML tags

Does the variable exist and have a non-null value? And optionally, does its content match the pattern? This is an Eval plugin.


variable="name[ operator pattern]"

Choose variable to test. Valid operators are '=', '==', 'is', '!=', '<' and '>'.

Examples of how this Eval plugin exists in <if> documentation and the If tags tutorial.
