    Assuming one line at a time:


    $betterline = ($line -match "\(\d+\)(?:\w+\(\d+\))+$") -replace "\(\d+\)", "."

    This first matches the line to grab the end part, then replaces the numbers and parentheses with a dot.

    For the future, I strongly recommend you learn regex – it’s simple yet invaluable. A great reference/tutorial for regex is regular-expressions.info.
