Vba 替换方括号+；将内容作为合并字段的内容

我试图将方括号中的内容更改为合并字段。我有80个ish文档要处理，有些没有方括号，有些有几个（没有嵌套）

我已经成功地运行了我的代码，它对一些文件起到了作用。其他人（多数）给出了溢出错误。当我检查其中一个文件中发生的情况时，代码正确地提取了内容，它只是将合并字段放在了错误的位置，这反过来会导致它继续查找相同的方括号集

Public Function searchFiles(fFile As Variant, rootFolderStr2 As String, rootFolderStr As String)
    Dim strTemp As String, mfc As String, msg As String
    Dim startStr As Integer, endStr As Integer
    Dim objWord As New Word.Application
    Dim objDoc As Word.Document
    Dim aField As Field, fFolder As String
    Dim rng As Variant, myField As Field, oldField As Variant

    On Error GoTo ErrorHandler

    'open file
    'Open fFile For Input As #1
    Set objDoc = objWord.Documents.Open(fFile)
    objDoc.TrackRevisions = False
    strTemp = objDoc.Range(0, objDoc.Range.End)

    startStr = InStrRev(strTemp, "[")
    endStr = InStrRev(strTemp, "]")

    Do While startStr <> 0
        'Merge field contents
        mfc = Right(Left(strTemp, endStr - 1), endStr - startStr - 1)
        Set rng = objDoc.Range(startStr - 1, endStr)
        Set myField = objDoc.Fields.Add(Range:=rng, Type:=wdFieldMergeField, Text:=mfc)

        strTemp = objDoc.Range(0, objDoc.Range.End)

        'Find next merge field
        startStr = InStrRev(strTemp, "[")
        endStr = InStrRev(strTemp, "]")
        If endStr < startStr And endStr <> -1 Then
            msg = "Error occured in " & fileName & " " & startStr & " " & endStr
            Debug.Print (msg)
            startStr = 0
            endStr = 0
        End If
    Loop
    'put in right folder
    fFolder = Right(objDoc.FullName, Len(objDoc.FullName) - Len(rootFolderStr))

    objDoc.SaveAs fileName:=rootFolderStr2 & "\" & fFolder
    objDoc.Close
    objWord.Quit

ErrorHandler:
If Err.Number <> 0 Then
    Debug.Print ("Error occured in file: " & fileName & " " & Err.Description)
    Exit Function
End If

我正在努力理解word中的对象是如何工作的，所以请原谅

如果您能回答导致此问题的原因，或能提供更好的解决方法，我们将不胜感激。

好的。一般建议总是，总是，总是把选项显式地作为模块或类的开始。这有助于突出显示代码中与语法滥用和未声明变量等相关的错误。在发布的代码中有一个未声明的变量“Filename”

使用Word时，最好尝试找到一种使用Word对象模型的方法，而不是提取文本

您可以通过使用.MoveStart/EndUntil方法替换instrrev来修改现有代码

我已经更新了您的代码以使用这些移动方法

如果您不了解关键字的作用，请将光标放在关键字上，然后按F1。这将带您进入MS帮助页面。对于Word对象模型，帮助页需要仔细阅读
