String-Bearbeiten (Filtern, Löschen, etc.)

[s.h.a.r.k]

Schon mal die folgenden Proceduren probiert:

Delphi-Quellcode:

Pos Routine
 
Returns the index value of the first character in a specified substring that occurs in a given string.
 
Unit: System 

function Pos(const substr: string, const str: string): Integer;
function Pos(const substr: WideString, const str: WideString): Integer;


Description 
In Delphi, Pos searches for a substring, Substr, in a string, S. Substr and S are string-type expressions.
Pos searches for Substr within S and returns an integer value that is the index of the first character of Substr within S. Pos is case-sensitive. If Substr is not found, Pos returns zero.
The PosEx function is similar to Pos, but provides additional features and can be used in C++ code.

Delphi-Quellcode:

Copy(...)
Returns a substring of a string or a segment of a dynamic array.
