Getting specific numbers from a URL path using regex

Trying to extract the numbers 123456 from three different URL paths:

/aaa/bbb/co1-e3ee1ddd-3333s1-123456/art-1?unitId=art(1)par(5)

/aaa/bbb/cos-123456/art-1

/aaa/bbb/cos-123456?unitId=art(1)

Tried using (\d+) but it matches all numbers instead.

Answer №1

My solution involves creating a regular expression that identifies strings with at least eight digits (since document numbers must have at least eight digits). I then compare this regex result with another set of regex results to determine the longest match. While this approach works, it is important to note that it may be sensitive to changes in the number of digits within the document number.

urlWithoutRoutePath.match(new RegExp('(\\d{8,})\\b', 'ig'))
