Question

我必须（将）使用FDM（免费下载管理器）从INSEE（法国统计局）下载一百个文件。所以我用一个脚本来重命名那些下载的文件，找到每个公社的五位数Insee代码（在文件的第二行）并将它们放在文件名之前，所以 rp009_cc_pop.xls 成为 67181_rp009_cc_pop.txt 。那些下载的.xls文件不是真正的Excelfiles，而是具有错误扩展名的纯文本文件。有时会有一个下载的文件，其内容中没有“commune”（带空格）字样。如何跳过这些文件的重命名。所以一个好的建议是昂贵的。这是脚本：

Dim objFso, strFolder
 ' Begin Main
 Set objFso = CreateObject("Scripting.FileSystemObject")
 strFolder = objFso.GetParentFolderName(WScript.ScriptFullName)  
 If objFso.FolderExists(strFolder) Then
 Call GetJspFiles(objFso.GetFolder(strFolder))
End If
Set objFso = Nothing
' End Main

Sub GetJspFiles(ByRef objFolder)
Dim objFile, objSubFolder
For Each objFile In objFolder.Files
    If LCase(objFso.GetExtensionName(objFile.Name)) = "xls" Then
        Call JSPRename(objFile.Path, objFolder.Path)
    End If
Next
For Each objSubFolder In objFolder.SubFolders
  Call GetJSPRename(objSubFolder)
Next
' objFile.Close
End Sub

Sub JSPRename(ByRef strPath, ByRef strFolder)
Dim arrText, strText, strTextLine, Position , objJspFile, newFilename, strVerz
Set objJspFile = objFso.OpenTextFile(strPath)
arrText = Split(objJspFile.ReadAll, vbCrLf) ' split into lines
For Each strTextLine In arrText
  If strTextLine <> "" Then
     strText = Trim(strTextLine)
   If Instr(1,strText,"Commune ",1) Then
    Position=Instr(1, strText, "(",1)
   newFilename=mid(strText,Position+1, 5) ' 5 Characters long
   else
   end if
else
' newFilename=......  ' <== skip those files without the word 'commune ' from renaming
  end if
Next
objJspFile.Close
cutlastoff=Left(strPath, inStrRev(strPath,"\")-1)
strNewName = cutlastoff & "\" & newFilename & "_rp009_cc_pop.txt"  ' cutting the filename
Wscript.echo "New Name: " & strNewName & vbcrlf & "Old Name: " & strPath 
'!! only for Showing the results

objFSO.MoveFile strPath, strNewName
End Sub

非常感谢任何欢迎提示

我通常在原始for循环中使用嵌套循环，而任何其他循环都可以跳过项目。您必须确保嵌套循环不会循环，因此您的原始脚本不会受到影响，因此使用Do {...}循环时为假。

For Each strTextLine In arrText : Do 'Easy skip door
  If strTextLine <> "" Then
     strText = Trim(strTextLine)
   If Instr(1,strText,"Commune ",1) Then
    Position=Instr(1, strText, "(",1)
   newFilename=mid(strText,Position+1, 5) ' 5 Characters long
   else
   end if
else
   Exit Do 'Take the easy skip door
' newFilename=......  ' <== skip those files without the word 'commune ' from renaming
  end if
Loop While False : Next 'Don't forget to close the skip door.

编辑：道歉，我想我太兴奋了，不能做我的第一篇文章。我会留下原帖，提醒我下次不要太快。

下面的Sub会将布尔变量初始化为False以用作开关。然后它将查找您的值，如果找到它，则将布尔变量设置为True，并根据该布尔变量的值执行其余代码。

Sub JSPRename(ByRef strPath, ByRef strFolder)

    Dim boolNumberFound, arrText, strText, strTextLine, Position , objJspFile, newFilename, strVerz

    boolNumberFound = False '<-----------
    Set objJspFile = objFso.OpenTextFile(strPath)
    arrText = Split(objJspFile.ReadAll, vbCrLf) ' split into lines


    For Each strTextLine In arrText
        If strTextLine <> "" Then
            strText = Trim(strTextLine)
            If Instr(1,strText,"Commune ",1) Then
                Position=Instr(1, strText, "(",1)
                newFilename=mid(strText,Position+1, 5) ' 5 Characters long
                boolNumberFound = True '<-----------
                Exit For
            end if
        end if
    Next

    If boolNumberFound Then '<-----------
        objJspFile.Close
        cutlastoff=Left(strPath, inStrRev(strPath,"\")-1)
        strNewName = cutlastoff & "\" & newFilename & "_rp009_cc_pop.txt"  ' cutting the filename
        Wscript.echo "New Name: " & strNewName & vbcrlf & "Old Name: " & strPath 
        '!! only for Showing the results

        objFSO.MoveFile strPath, strNewName
    Else
        Wscript.echo "Commune # not found in file: '" & strPath & "'. File was skipped."
    End If

End Sub

我还冒昧地使用正则表达式对象编写子版本的新版本。这些更快，更灵活。我没有测试它。根据自己的喜好使用它。

Sub JSPRename(ByRef strPath, ByRef strFolder)

    Dim objJspFile, CommuneNo, arr_path, strNewName
    Dim re, re_matches, re_first_match

    Set objJspFile = objFso.OpenTextFile(strPath)
    Set re = New RegExp

    re.Pattern = "(Commune *\()(\d{5})" 
    'A match will return 2 submatches:
        'submatch(0)="Commune("
        'submatch(1)=[Your 5 digits]

    Set re_matches = re.Execute(objJspFile.ReadAll)

    If re_matches.count Then 'There is at least 1 occurence
        Set re_first_match = re_matches(0)
        CommuneNo = re_first_match.SubMatches(1)
    Else
        WScript.Echo strPath & " did not contain Commnune# and was skipped."
        Exit Sub 'This exits your sub without renaming the file
    End If

    Set re = Nothing

    objJspFile.Close
    Set objJspFile = Nothing


    arr_path = Split(strPath, "\")
    arr_path(UBound(arr_path)) = CommuneNo & "_" & arr_path(UBound(arr_path))
    strNewName = Join(arr_path, "\")

    Wscript.echo "New Name: " & strNewName & vbcrlf & "Old Name: " & strPath 
    '!! only for Showing the results

    objFSO.MoveFile strPath, strNewName

End Sub

运行IF然后循环异常
