Filter records from XML response while writing file

Content

Team,

We are not seeing option to filter records received from WS while writing to a file. There are 120 records in response XML and we need to exclude 35 records. We have primary identifier of those records. We are writing file using For each of record element(Res_rec_element).

Is there a way to add NOT IN condition along with For Each Res_rec_element? Or any other way to achieve filtering/exclusion of records from response?

Regards
