Even with ERE, you need to run it twice, perhaps conditionally if the first hits, as you used both start and end field '|'. Otherwise, you miss the following adjacent fields on a line like: "123.|456."
You can add pipes to both ends for the substitute and then remove them:
I could have removed both added pipes with one substitute "s/^|\(.*\)|$/\1/" but these back references are a bit slower, in my experience, so I avoid them where possible.
Two passes can be avoided if a less careful pattern is sought, like "s/\([0-9]\).|/\1/", as it encompasses only one pipe. It mangles any non-numeric field with a trailing numer and dot, like "123|The field count of this line is 3.|xyz".
