For instance, I am looking to extract the numbers that do not have 'the', 'abc', or 'he' before them;
the89 (no match)
thisis90 (match 90)
iknow89999 (match 89999)
getthe984754 (no match)
abc58934(no match)
he759394 (no match)
I attempted to use this pattern (?<!(the|abc|he))[0-9]+
, but it did not work as expected.
