How to filter example values based on the attribute names ?

Dear all,

I propose an easy challenge in appearance (in appearance only)...  After many tests, I must admit that 
I'm totally stuck.

My process produces an example set with some attributes (the number of generated attributes is variable according to the set-up of the user) : 


For a given attribute, I want to filter the example values based on the attribute name : 
 - if the example value contains the attribute name, then the example is conserved.
 -  if the example value does not contain the attribute name, then the example is removed.
To perform this task, I try to used a Filter Examples operator inside a Loop Attributes subprocess with the following set-up : 
 - condition class = expression and parameter expression
  = > this solution produces an empty example set !

 - condition class = custom_filters and   filters = 


 = > this solution raises an error ("Instantiation error")


So I'm searching a 100 % native RapidMiner process (no Python / R scripts) to filter example values based on the 
attribute name. Is it possible ?

My data (.pdf file) is in attached file.
My process :

    Hi @lionelderkrikor

    I think @Telcontar120 is referring to the fact that the custom filters in Filter Examples cannot handle macros in the attribute field, while Select Attributes can. So you have to circumvent this. I would just use a Rename operator with renaming the %{loop_attribute} to current_attribute (or similar and using this in the Filter Examples. And renaming the current_attribute back to %{loop_attribute}.
