XPath query for list of UML class attributes that are not associations [message #1752826]

I have a UML model developed with Rational Software Architect v9.1.2. I'm crafting a BIRT report with which I would like to show all of the class attributes that are NOT associations. I have the following XPath query:

resolveURI($classURI)/ownedAttribute[not(@association)]

This query returns all (2) of the attributes on the sample class EmailAddress, screen shot and xmi model fragment attached, both the String address and the association emailAddressStatus.
index.php/fa/28247/0/

It seems that the @association attribute is not recognized. This might be a namespace issue, but I'm not sure. Can anyone offer help, or suggest an alternative approach?

Hi

While I never use BIRT, I was involved on some of the integration activity for OCL, so I know that it once worked.

XPath is nice and compact, but the "X" for extensible means that typos are extensions returning null.

You might try OCL where typos are errors. I doubt that the UI has been integrated into BIRT, so you might want to parctice your OCL expressions using the Xtext OCL Console.

Thanks for the tip Ed! I instead employed OCL and this query did the trick:

oclQuery(resolveURI($classURI)/ownedAttribute, "self.association = null")
