ATTRIBUTES

• NAME

  This is the name of the parameter to test. It is resolved like any other parameter name. (q.v. VAR for more info.)

• VALUE

  If VALUE is set, then a comparison operation is done. The value of NAME is compared to VALUE using the value of OP.

• OP

  If VALUE is set, then this is checked. If it isn't present, then '==' (numeric equality) is assumed. OP must be one of Perl the numeric comparison operators or the string comparison operators. All 6 of each kind is supported.

  Note: If you want to use < or <=, you must instead use &lt; or &lt;=. This is to make sure it will parse with XML::Parser. You should not need to use &gt; or &gt;= instead of > and >=, respectively.

• IS

  If VALUE is not set, then IS is checked. IS is allowed to be either "TRUE" or "FALSE". The boolean value of NAME is checked against IS.

CHILDREN

None

EFFECTS

None

DEPENDENCIES

None

USAGE

<if name="__ODD__" is="false">
  ... Children here
</if>

In the above example, the children will be executed if the value of __ODD__ (which is set by the LOOP node) is false. So, for all even iterations.
