Your question is a bit unclear but you can do this in a variety of ways in RapidMiner. One approach would be to use Extract Macro or Generate Macro and Loop Examples to set these macros for each example in your dataset and then do whatever you are planning with this macro.

You can fix this if you harmonize your dataset to ensure that all records have the same attributes, even if they are blank or missing.
