I want to filter a set of Items whether an attribute is empty or not. I Have tried using matches:
@ATTR.Matches('^$') that is supposed to identify empty strings(?). I want to do this both for an enumeration attribute and a string attribute.
How can I do this?
It does. I thought I tried that yesterday without success. Thanks!
Hello, I have similar question here: is there any way I can check if <List> object is empty?
You can use which counts the number of object in a list.
There is a rather elegant, but possibly a bit abstract, example in the Help manual, on the "[ ] Operator":
Returns all report sections without any subsection.
