if-global-variable

<if-global-variable> performs a test on a global configuration value (GCV). The type of test performed depends on the operator specified by the op attribute. The following table shows the type of test performed by each operator.

operator	Returns true when...
available	there is a global configuration value with the specified name.
equal	there is a global configuration value with the specified name and its value equals the content of the condition when compared using the specified comparison mode. Supports variable expansion.
lt	there is a global configuration value with the specified name and its value is less than the content of the condition when compared using the specified comparison mode. Supports variable expansion.
gt	there is a global configuration value with the specified name and its value is greater than the content of the condition when compared using the specified comparison mode. Supports variable expansion.
not-available	available would return false.
not-equal	equal would return false.
not-lt	lt would return false.
not-gt	gt would return false.

Examples

<if-global-variable name="myGlobalVariable" op="available"/>

<if-global-variable mode="nocase" name="myGlobalVariable" op="equal">enabled</if-global-variable>
