Description
Converts a string matching/containing the regex (?:(?:\()?\s*\d+\s*,\s*\d+\s*(?:\))?\s*;\s*)*(?:\()?\s*\d+\s*,\s*\d+\s*(?:\))? to a TPointArray. The regex allows for a lot of flexibility when it comes to the format of the entered string. The TPointArray can be converted back to a string with TPAToStr.
Example
begin
WriteLn(TPAToStr(StrToTPA('(1,2);(3,4);(5,6)')));
WriteLn(TPAToStr(StrToTPA('Hello(1,2);(3,4);(5,6)World')));
WriteLn(TPAToStr(StrToTPA('(1 ,2) ;( 3 ,4 );(5 ,6)')));
WriteLn(TPAToStr(StrToTPA('1,2;(3,4);(5,6)')));
WriteLn(TPAToStr(StrToTPA(' 1, 2;3, 4;5, 6')));
end.Output:
(1,2);(3,4);(5,6) (1,2);(3,4);(5,6) (1,2);(3,4);(5,6) (1,2);(3,4);(5,6) (1,2);(3,4);(5,6)
