I'm new to programming in Delphi 7, as well as regular expressions.
Delphi 7 because in the company I'm working on, for other reasons, they have to use Delphi 7.
I need to work with regular expressions, someone knows some way. From what I read, there's a library for it, could anyone give me a map?
For versions prior to XE, there are alternatives like TRegExpr that is free.
In newer versions of Delphi there is native support , the unit ( unit ) to be used is System.RegularExpressions .
A simple example replacement: p>
function TForm1.ReplaceCC(const Match: TMatch): string;
begin
i := i + 1;
Result := InttoStr(i);
end;
procedure TForm1.Button1Click(Sender: TObject);
var
regex: TRegEx;
input: string;
myEval: TMatchEvaluator;
begin
i := 0;
input := Edit1.Text;
regex.Create('cc');
myEval := ReplaceCC;
Edit2.Text := regex.Replace(input, myEval);
end;
There is also the open source library System.RegularExpressionsCore.TPerlRegEx implementing regular expressions compatible with Perl .
