As usual, TIMTOWTDI (There is more than one way to do it)...

A straightforward way:

Split the input lines on the pipe symbols:

    ($name, $email, $city) = split '|', $inputline;

Remove the words ending in ':' at the beginning of each item:

    for ($name, $email, $city) {
        s/^\w+:\s*//;
    }

Format the output line:

    $outputline = ' 'x19.sprintf '%-40.40s%-90.90s%s', $name, $city, $email;

In the sprintf format, %-40.40s means
- left align (-)
- using at least 40 positions (the first 40 of the two)
- using at most 40 positions (the .40)
- a string (s)
Precede the name by 19 spaces (' 'x19) in order to start at position 20.
