I have a few additional generic attributes with specific values (meaning of them are in a separate codelist)  in my CityGML dataset. Now I want to test them with the transformer "Filter" an sort them by the gml:id. Then I want to write them in an Excel-file or text file. Some attributes are also in the buildingpart with means I need a multidimensional output maybe as xml-file. How can I test only one attribute with the transformer "Filter"?

 

My intention is to build a row of transfomers and every transformer is testing one attribute. At the end I want to write a protocol with invalid datasets. Any ideas? Best regards, Frank
