Hello there,

Just wonder how can a "if" conditional can be used to detect the case where an attribute is empty (not null) like:

	Source code
1	name="" fov="" width=""

Used to work with this one for single conditional but it's not working when mixed with other condition.

	Source code
1	if(element[name].attribute == , then_action(););

AFAIK this is not the case for null attribute as in this case it's there but it just doesn't have any value.

Thanks in advance! *thumbsup*

Just found the solution myself, post it here if anybody else needs it.

	Source code
1	if(!element[name].attribute, then_action(););

That way it can be used aside other conditionals.
