Modify expression in notepad++

I have a file so that each line is like this:

A|B

How can I change it using a regex so that I can have this as final res开发者_开发技巧ult:

A|1|||B|||

Example: 1ARC00138|34 results in 1ARC00138|1|||34|||

---

Find:

(.+)\|(.+)

Replace with:

\1|1|||\2|||

---

This replacement regex:

s/^(.*)\|(.*)$/\1|1|||\2|||/
