Pascalban hogy lehet lekezelni egy 500 ezer (vagy több) karakteres stringet? Egyáltalán le lehet?

Egy focibajnokság éves adatait akarom feldolgozni. Az adat AJAX-en keresztül jön a szerverről HTML-be és azt kell feldolgozni, változókba rakni, stb.

Itt egy példa, ami valójában csak 1 sor a html-ben. A valóságban ez persze sokkal hosszabb:
