TIBCO 设计器中的“text()=0”是什么意思？

Question

In one of the TIBCO Designer .process files I found an expression like this: $SomeValue/text()=0 .

What does it mean?

That $SomeValue is null or blank, or what?

Answer 1

Its evaluating the value to a Boolean.. meaning if text() is zero, then the field for which it is mapped becomes true. Generally () are not seen in the xpath values, would be great if you could post the exact statement.
