Question

我需要结合这两个正则表达式将^.*(Completed: BALI - Job).*$和\b(BALI_)(INVOICES|CORRESPONDENCE|LATE_SCANNINGS)\b合并为一个，以便"Completed: BALI - Job"作为强制匹配，"BALI_INVOICES or BALI_CORRESPONDENCE or BALI_LATE_SCANNINGS"作为替代

Answer 1

扩展David-SkyMesh的答案，使第一部分成为强制性，三个备选方案的第二部分可选：

/ (                                                           # capture
    (?:Completed: BALI - Job)                                 # this
                                                              # AND optionally
                                                              # one of these
    (?:\bBALI_(?:INVOICES|CORRESPONDENCE|LATE_SCANNINGS)\b)?  
  )
/x                       # ignore whitespace & comments in regexp itself

Answer 2

由于第二部分是可选的，因此附加?。

^.*(Completed: BALI - Job).*(\b(BALI_)(INVOICES|CORRESPONDENCE|LATE_SCANNINGS)\b)?
