Advanced / tag

tag(tagPath)

Returns the value of the tag at the path specified. Normally, you'd use the expression language's built-in bound-value syntax to use a tag value in an expression. What makes this function useful is that the path itself can be the result of an expression, meaning it can be dynamic.

tag("Tanks/Tank5")

... returns Tank5's value.

tag("Tanks/Tank" + {Root Container.TankNum})

... returns the value for the tank represented by the dynamic property TankNum on the Root Container.
