We compare files which contain several datasets within one file.
there is a request from the users to compare only a certain part of the file.
The lines we like to compare have a certain value at a specific place.
a solution cab be that these values can be in- or excluded from the compare
Have you checked Regular expressions support? You can ignore lines, which follow some pattern. At the moment I could not tell how to include only specified lines, but I will think about it.
