Delphi通过子字符串搜索比较两个字符串列表，并将匹配项合并到另一个字符串列表中

我试图通过子字符串搜索比较2个stringlist，并将找到的项匹配到另一个stringlist

“Stringlist\u SCSILogical单元”包含以下数据：

SCSIBus=0;SCSILogicalUnit=0;SCSIPort=1;SCSITargetId=0;Status=OK
SCSIBus=0;SCSILogicalUnit=1;SCSIPort=2;SCSITargetId=0;Status=OK
SCSIBus=0;SCSILogicalUnit=2;SCSIPort=2;SCSITargetId=0;Status=OK
SCSIBus=0;SCSILogicalUnit=3;SCSIPort=2;SCSITargetId=0;Status=OK
SCSIBus=0;SCSILogicalUnit=4;SCSIPort=2;SCSITargetId=0;Status=OK
SCSIBus=0;SCSILogicalUnit=43;SCSIPort=2;SCSITargetId=0;Status=OK
SCSIBus=0;SCSILogicalUnit=44;SCSIPort=2;SCSITargetId=0;Status=OK
SCSIBus=0;SCSILogicalUnit=45;SCSIPort=2;SCSITargetId=0;Status=OK
SCSIBus=0;SCSILogicalUnit=46;SCSIPort=2;SCSITargetId=0;Status=OK

  LocationInformation    REG_SZ    Port(2,2,3,3) Bus 0, Target ID 0, LUN 67
;
    LocationInformation    REG_SZ    Port(2,2,3,3) Bus 0, Target ID 0, LUN 43
;
    LocationInformation    REG_SZ    Port(2,2,3,3) Bus 0, Target ID 0, LUN 44
;
    LocationInformation    REG_SZ    Port(2,2,3,3) Bus 0, Target ID 0, LUN 45
;
    LocationInformation    REG_SZ    Port(2,2,3,3) Bus 0, Target ID 0, LUN 50
;
    LocationInformation    REG_SZ    Port(2,2,3,3) Bus 0, Target ID 0, LUN 51
;

“Stringlist_LUN”包含以下数据：

SCSIBus=0;SCSILogicalUnit=0;SCSIPort=1;SCSITargetId=0;Status=OK
SCSIBus=0;SCSILogicalUnit=1;SCSIPort=2;SCSITargetId=0;Status=OK
SCSIBus=0;SCSILogicalUnit=2;SCSIPort=2;SCSITargetId=0;Status=OK
SCSIBus=0;SCSILogicalUnit=3;SCSIPort=2;SCSITargetId=0;Status=OK
SCSIBus=0;SCSILogicalUnit=4;SCSIPort=2;SCSITargetId=0;Status=OK
SCSIBus=0;SCSILogicalUnit=43;SCSIPort=2;SCSITargetId=0;Status=OK
SCSIBus=0;SCSILogicalUnit=44;SCSIPort=2;SCSITargetId=0;Status=OK
SCSIBus=0;SCSILogicalUnit=45;SCSIPort=2;SCSITargetId=0;Status=OK
SCSIBus=0;SCSILogicalUnit=46;SCSIPort=2;SCSITargetId=0;Status=OK

  LocationInformation    REG_SZ    Port(2,2,3,3) Bus 0, Target ID 0, LUN 67
;
    LocationInformation    REG_SZ    Port(2,2,3,3) Bus 0, Target ID 0, LUN 43
;
    LocationInformation    REG_SZ    Port(2,2,3,3) Bus 0, Target ID 0, LUN 44
;
    LocationInformation    REG_SZ    Port(2,2,3,3) Bus 0, Target ID 0, LUN 45
;
    LocationInformation    REG_SZ    Port(2,2,3,3) Bus 0, Target ID 0, LUN 50
;
    LocationInformation    REG_SZ    Port(2,2,3,3) Bus 0, Target ID 0, LUN 51
;

我需要匹配“LUN”值和“SCSILOGICUNIT”值之间的响应（LUN和SCSILOGICUNIT具有相同的值LUN=SCSILOGICUNIT），以便可以在“Stringlist\u结果”中侦听结果。 结果应该是这样的

"SCSIBus=0;SCSILogicalUnit=46;SCSIPort=2;SCSITargetId=0;Status=OK =>>> LocationInformation    REG_SZ    Port(2,2,3,3) Bus 0, Target ID 0, LUN 46
;"

我正在使用以下函数，但结果不一致：

function stringlist_mmg_FastJoin(List1, List2: TStringList): TStringList;
var
  L1Idx, L2Idx,
  L1Max, L2Max: Integer;
  v: Integer;
begin
  // Create Result list, set it's min size
  Result := TStringList.Create;
  Result.Capacity := Max(List1.Count, List2.Count);
  // limits
  L1Idx := 0;
  L2Idx := 0;
  L1Max := List1.Count;
  L2Max := List2.Count;
  // forse sort
  List1.Sorted := True;
  List2.Sorted := True;

  // iterate
  while (L1Idx<L1Max) and (L2Idx<L2Max) do
  begin

if pos(extracttextbetween(List1[L1idx],'SCSILogicalUnit=',';'),List2[L2idx])>1  then


    begin
      Result.Add(List1[L1Idx]+' = '+List2[L2idx]);
      Inc(L1Idx);
      Inc(L2Idx);
    end

    else if v < 0 then                              // Add from List 1
    begin
      //Result.Add(List1[L1Idx]);
      Inc(L1Idx);
    end
    else // v > 0                                   // Add from List 2
    begin
      //Result.Add(List2[L2Idx]);
      Inc(L2Idx);
    end;
  end;
  // Add all remainders from second list
  while L2Idx < L2Max do
  begin
    //Result.Add(List2[L2Idx]);
    Inc(L2Idx);

  end;
  end;



stringlist_resultat:=Tstringlist.create;
stringlist_rezultat.addstrings(stringlist_mmg_FastJoin(Stringlist_SCSILogicalUnit,stringlist_LUN));

当我运行这个函数时，我得到一个单一的结果

有人能告诉我我做错了什么吗？ 在没有stringlist的情况下可以获得此任务吗

谢谢大家!

将其重命名为仅加入，不能声称其快速

function stringlist_mmg_Join(const LogicalUnitList, LUNList: TStringList): TStringList;
const NotFound = -1;

  function ExtractTextBetween(const Txt, StartTag, EndTag : string; out iValue : integer): Boolean;
  var
    value : string;
    iStartTag, iEndTag : integer;
  begin
    Result := False;

    iStartTag := Pos(StartTag, Txt);
    if (iStartTag = NotFound) then Exit;

    iEndTag := PosEx(EndTag, Txt, iStartTag);
    if (iEndTag = NotFound) then Exit;

    Inc(iStartTag, Length(StartTag));
    Value := MidStr(Txt, iStartTag, iEndTag-iStartTag);
    Result := TryStrToInt(Value, iValue);
  end;

var
  i, v, ix: Integer;
begin
  Result := TStringList.Create;

  // iterate, Parse and write Value as Object
  for i := 0 to LogicalUnitList.Count - 1 do begin
     If ExtractTextBetween(LogicalUnitList[i], 'SCSILogicalUnit=', ';', v) then begin
       LogicalUnitList.Objects[i] := Pointer(V+1);
     end;
  end;

  // iterate, Parse and write Value as Object
  for i := 0 to LUNList.Count - 1 do begin
     If ExtractTextBetween(LUNList[i] + ';', 'LUN ', ';', v) then begin
       LUNList.Objects[i] := Pointer(V+1);
     end;
  end;

  // Match
  for i := 0 to LogicalUnitList.Count - 1 do begin
    ix := LUNList.IndexOfObject(LogicalUnitList.Objects[i]);
    if (ix = NotFound) then Continue;
    Result.Add(LogicalUnitList[i] + '  =>>>' + LUNList[ix] + ';');
  end;
end;

输出为：

SCSIBus=0;SCSILogicalUnit=43;SCSIPort=2;SCSITargetId=0;Status=OK  =>>>    LocationInformation    REG_SZ    Port(2,2,3,3) Bus 0, Target ID 0, LUN 43;
SCSIBus=0;SCSILogicalUnit=44;SCSIPort=2;SCSITargetId=0;Status=OK  =>>>    LocationInformation    REG_SZ    Port(2,2,3,3) Bus 0, Target ID 0, LUN 44;
SCSIBus=0;SCSILogicalUnit=45;SCSIPort=2;SCSITargetId=0;Status=OK  =>>>    LocationInformation    REG_SZ    Port(2,2,3,3) Bus 0, Target ID 0, LUN 45;

你应该使用字典来解决这个问题。将这两个文件解析成键入Lum值的字典。你能提供一个例子吗？没有真正的动机这样做。有很多关于不同部分的例子，而且Delphi2010是古老的，它的通用集合有点古怪。尽管对于这个简单的任务，它们可能工作得很好。如果我是你，我会用正则表达式进行解析，剩下的就由字典来完成。一旦你有了合适的工具，代码基本上是自己编写的，你就可以扔掉这里的很多东西。50 rep可能不足以激励任何人。这只是一个好问题的答案。这样做对我们来说更有趣。这个函数的结果是错误的：SCSIBus=0；单位为0；SCSIPort=2；SCSITargetId=0；状态=正常=>>>端口（2,2,3,3）总线0，目标ID 0，LUN 67它将SCSILogicUnit=0与LUN 67匹配；；谢谢你，弗雷德斯！这很好用。你应该得到赏金！
