Averaging on extracted data

[octavia2]

Hi,
I manage to extract digits from an html page, with the use of Xpath (//*[contains(@data-label, 'Moyenne') and contains(@class, 'ng-scope')]).
I therefore output one note per line.
Sample:

    19.5
    17
    19.3
    17.6
    17
    19.5
    19.5
    17.7
    18.2

Is it possible to obtain the average of these scores rather than their detail?
Thanks

that's outside the scope of this software, but you can just copy+paste into google spreadsheets
