Given a keyword Product data sheet how can I extract 3rd line only after that match.

For example, given below data, output should be XB4BW84M5

Product data sheet
Characteristics
XB4BW84M5

I have tried (Product data sheet)rn(.*?)(^.*rn)3 but, that is to find something preceeded by 2 lines then the key word but, it extracts all 3 lines I need the 3rd only

Use this pattern: (?<=Product data sheet)r?n.+r?n(.+)

Explanation:

(?<=Product data sheet) - assert that what's preceding is Product data sheet

If assertion is true, then it matches new line character with r?n, then matches whole line with .+, which is "match one or more of any characters", then again, in order to match newline I used r?n and then used (.+) to store in capturing group second line after desired string.

  @TimBiegeleisen Then this would become impossible to achieve, as it would require positive lookbehind of variable length, which is only allowed in .NET. Moreover, what regex tools? I don't know any that doesn't support capturing group.

  A wrong match is likely if third line doesn't exist. You'd better replace s* with r?n at least.
