Delphi TPerlRegEx 正则表达式替换字符《LceMeaning》

以下代码经本人在Delphi XE2 下编写并通过。

function Matching(Code,MName,Temp,Source: string) : string;
var
  qryQuery : TADOQuery;
  sql,Balance,SouStr : string;
  reg: TPerlRegEx;
begin
  reg := TPerlRegEx.Create;
  qryQuery := Tadoquery.Create(Application);
  qryQuery.Connection := Form1.con1;
  sql := 'select * from CustomerInfo where CardsName1='''+Code+'''';
  qryQuery.Close;
  qryQuery.SQL.Clear;
  qryQuery.SQL.Add(sql);
  qryQuery.Open;
  if qryQuery.RecordCount > 0 then
    begin
      Balance := qryQuery.FieldByName('Balance').AsString;
    end
  else
    Balance := '';
  //会员编号
  reg.Subject := Source;
  reg.RegEx := '@';
  reg.Replacement := Code;
  reg.ReplaceAll;
  SouStr := reg.Subject;
  //会员姓名
  reg.Subject := SouStr;
  reg.RegEx := '-';
  reg.Replacement := MName;
  reg.ReplaceAll;
  SouStr := reg.Subject;
  //会员金额
  reg.Subject := SouStr;
  reg.RegEx := '&';
  reg.Replacement := Temp;
  reg.ReplaceAll;
  SouStr := reg.Subject;
  //会员余款
  reg.Subject := SouStr;
  reg.RegEx := '#';
  reg.Replacement := Balance;
  reg.ReplaceAll;
  SouStr := reg.Subject;

  Result := SouStr;
  FreeAndNil(reg);
  qryQuery.Free;
end;
