Missing XML tags create literal instead of variables

When receiving an XML file, some tags are not necessary and do not exist. When testing in a Branch statement inside of Integrator, it decides that it’s not a variable and tests as a literal.

For example.
Missing element:
In a Branch statement: %Width%<>’’
But since Width does not exist, the previous statement is true.

Does anyone know of a way to get around this so that the statement is false and does not execute?

Thanks,

This expression would likely work…

%Width%<>’’ and %Width%<>$null
