This is just another quick example of Regex pattern.
Next pattern matches “at least one symbol which is letter or digit at the begging and then exactly one delimiter ‘|’ and then at least one symbol which is letter or digit in the end“:
Valid is:
ab123|cde45
Not valid are:
|ad
df|
adf||adf
and so on…
