Needle in haystack: Specific string followed by exact set of numbers
How can I search for ABC???? where ABC should be exactly that, but the ???? must be exactly four numbers, ideally followed by whitespace.
Illustrative examples:
LHRJFKABC1234 233<-- Has needleEABC123 LHRJFK<-- Does not have needle as only 3 numbers following ABC
Something tells me I need to search for string something like (\d{4}) for the 4 numbers. But not sure quite how to puzzle it all together.
What I've found so far:
- Regular expression to match standard 10 digit phone number
- Regular Expression to match specific string followed by number?

For things like this I find an online checker like Rubular very handy.
Unless I'm misunderstanding, the regex ABC\d{4}\s should work for you. Do you need groupings (i.e. to match the 4-digit part)?
