 The main file will have the filename 'foo' while all the un-needed (in this case at least) files will be ^foo\.\d{14}\.(log|xac)$ (in other words, the filename, followed by a period, followed by 14 digits, followed by a period, then either log or xac).  The main file will also usually be the newest (`ls -t | head -n1`).  The main file is not always the largest though.
