Data Diff with exceptions Question

So I'm currently developing an automated test system and I'm verifying my results by running a set of baselined data through and comparing the output (which is in a txt file) to a baseline results file. So of course I'm just using the diff command. Unfortunately each time I run the test there are 2 values that are changed. One is a uniq identifier and the other is a timestamp.

What is the best way to have my diff ignore those 2 values? Keep in mind I need to ignore the value and not the line. Dummy Example of the file below and the fields needing to be ignored highlighted in red.

Code:
XXMAP1234
094 LSAT    04Jan1751Z11 UBIB-UBIB
1234
XXCC
//FORMAT = text
//QUALITY = good
//EPT=<core:private ="upt:exo:/root/test/testing/v8" xmlns:session="ppt:exo:/root/Auto/metadata" identifier="4A9FF2D8-9A29-4E71-9546-F97F085C6C8" maliciouscode="none"


Thanks & Regards

hi,
cannot find a way with diff options only.

you may think to pre-process both file so that "words" matching the structure of the two highlighted texts may be removed in advance and then diff the resulting new files.

Well I did consider removing them but only issue with that is both fields are generated at the time that the test runs so I would have no way of knowing what to tell the script to remove. The timestamp is auto-generated and so is the identifier.

provide two sample files with different value to us, and your expect output.
