Answer 1

You may use

^([^|]*\|)((?:[^|]*\|){2})((?:[^|]*\|){3})

And replace with $1$3$2.

Details:

• ^ - start of a line
• ([^|]*\|) - Group 1 ($1) capturing zero or more chars other than | and then a literal |
• ((?:[^|]*\|){2}) - Group 2 ($2) capturing 2 sequences of the same pattern as in Group 1
• ((?:[^|]*\|){3}) - Group 3 ($3) capturing 2 sequences of the same pattern as in Group 1

The order is changed with the order of the backreferences in the replacement pattern.

To remove the 2nd, 3rd and 4th |, use a similar expression:

Find what: ^([^|]*\|)([^|]*)\|([^|]*)\|([^|]*)
Replace with: $1$2$3$4

Basically, you just manipulate the capturing group boudaries and the order of the backreferences in the replacement pattern, that is all.
