xml – 使用外语字符处理文本文件或字符串变量

2023年10月14日 216次阅读

我想使用VBA函数,例如LCase $()和下一个UCase(),我的test.xml文件是UTF-8编码的.下面的示例代码使用UTF-8内容加载文件：

Dim objFileSystem, objInputFile

Set objFileSystem = CreateObject("Scripting.fileSystemObject")
Set objInputFile = 
objFileSystem.OpenTextFile("c:\test.xml", 1)

inputData = objInputFile.ReadAll

objInputFile.Close

现在我尝试将内容转换为小写,然后将第一个字母更改为大写

Var = inputData
Var = LCase$(Var)

Select Case Len(Var)

Case 0
CapitilizeFirstLetter = ""

Case 1
CapitilizeFirstLetter = UCase(Var)

Case Else
CapitilizeFirstLetter = Ucase(Left(Var, 1)) & mid(Var, 2)

End Select

我尝试以名称test_edited.xml保存文件内容

FileUrl = "c:\test_edited.xml"

Set objStream = CreateObject("ADODB.Stream")
With objStream
    .Open
    .Charset = "utf-8" 'rosyjski iso-8859-5
    .Position = objStream.Size
    .WriteText=Var
    .Flush
    .Position = 0
    .Type     = 1 'binary
    .Read(3)      'skip BOM
    .SaveToFile FileUrl,2
    .Close
End With
Set objStream = Nothing

结果,第一个文件的内容是：

Nejznámější ŽENY, MODELY, herečka, zpěvačka

第二个是现在

Nejznámější ŽENY, MODELY, herečka, zpěvačka

而且我预计它会是这样的

Nejznámější ženy, modely, herečka, zpěvačka

我究竟做错了什么？

我正在使用Basic IDE ver 6.4.

所有代码应如下所示

Sub Main

'getting variable from outside
ChanNum = DDEInitiate("MacroEngine", "MacroGetVar")
Var$= DDERequest$(ChanNum, "vChannelOpisA")
    DDETerminate ChanNum


Var = LCase$(Var) ' converting utf-8 encoded string to lower case

'change first letter to upper case
Select Case Len(Var)

Case 0
CapitilizeFirstLetter = ""

Case 1
CapitilizeFirstLetter = UCase(Var)

Case Else
CapitilizeFirstLetter = Ucase(Left(Var, 1)) & mid(Var, 2)

End Select

'sending variable to outside of vb script
ChanNum = DDEInitiate("MacroEngine","MacroSetVar")
Var = "vChannelOpisA=" + CapitilizeFirstLetter
DDEExecute (ChanNum, Var)
DDETerminate ChanNum

End Sub

名为Var的变量最后应该是utf-8编码,以将它们写为xml文件.
我也可以从文件中读取一个字符串,而不是使用DDERequest获取它们.

最佳答案 根据我的经验,Vba utf-8,iso 8859-1可能很棘手,因为它取决于文件源编辑器和系统环境,如果unix或windows或mac …大多数文本源编辑器或系统使用ANSI.我建议你试试adodb,因为它可能会读取并呈现utf-8而另一个更好地写出utf-8.

...
Set objStream = CreateObject("ADODB.Stream")
...
Dim ftxt As object
...

const bufFile = "c:\test.xml"
const stf = "c:\test_edited.xml"
Dim vData As Variant
Dim ftxt As TextStream
'ADODB
adoRead.Charset = "unicode"
adoRead.Open
adoRead.LoadFromFile bufFile
vData = Split(adoRead.ReadText, vbCrLf)
'ado object to write
Set fil = fso.GetFile(stf)
Set ftxt = fil.OpenAsTextStream(ForWriting, TristateUseDefault)

'process your data as intended
For j = LBound(vData) To UBound(vData)
   'code to capitalize...
   '...
   'write to
   ftxt.WriteLine vData(j)
Next j

这个结构对我来说对法语字符有用,我认为它应该在utf-8或unicode字符集中相同.

干杯
