Q>:
Мне нужны функции для парсинга строк
A>:
Здесь представлен модуль, в котором я разметил много методов для подобной работы.
Некоторые функции поименованы по-шведски, но, может-быть, Вы сможете понять,
что они делают.

Вам потребуется один из методов, называющийся stringreplaceall, который
принимает при параметра - исходную строку, подстроку для поиска и подстроку
для замены, и возвращает измененную строку.
Будьте осторожны, если Вы меняется одну подстроку на другую, чьей частью
является первая. Вы должны делать это в два прохода, или Вы попадете
в бесконечный цикл.

Так, если Вы имеете текст, содержащий слово Joe, и Вы хотите все его вхождения
изменить на Joey, то Вы должны сделать сперва нечто похожее на:

text := stringreplaceall (text,'Joe','Joeey');

И потом

text := stringreplaceall (text,'Joeey','Joey');
