How to extract a file from a package for comparison purposes?

Is there a way to extract a single file, or set of files from a package in one of he OpenSuSE repositories? I simply want to compare a file that I have configured/made changes to, with the original version of that file as it was installed on my system. My head is hurting from attempting DuckDuckGo research (found no joy looking at documentation for Yast, RPM, and Zypper. Maybe, NOT certain, YUM but dunno if usable) and figure I will just ask the gurus in this forum... I am running OpenSuSE 15.4 and 15.5 with the KDE/Plasma desktop if that is helpful. Thanks in advance as always, Marc....
