VBA宏：捕获具有特定字符串的行并返回它

Question

我试图从模拟报告（.log）中捕获模拟结果。我想匹配“传递”和“失败”字符串并保存在其他结果文件中完成匹配的行，我将用于进一步操作Excel中。我无法匹配所需的行：我写的下面的子不仅写了所需的行而且写了所有的行。我不知道问题在哪里..

Sub generate_sim_results()

    Dim testResults  As String
    Dim InputFile As String
    Dim fso As Object
    Dim ObjFile As Object
    Set fso = CreateObject("Scripting.FileSystemObject")


    testResults = Application.ActiveWorkbook.Path & "\sim_results.log"
    If Len(Dir$(testResults)) > 0 Then
        Kill testResults
    End If


    InputFile = Dir(Application.ActiveWorkbook.Path & "\" & "*.log")
    InputFile = Application.ActiveWorkbook.Path & "\" & InputFile
    'Debug.Print InputFile

    fnum = FreeFile()
    Open InputFile For Input As #fnum
    Set ObjFile = fso.CreateTextFile(testResults)

    While Not EOF(fnum)

        Line Input #fnum, dataLine
        If InStr(1, dataLine, "passed", vbTextCompare) > 0 Or InStr(1, dataLine,"failed", vbTextCompare) > 0 Then
            ObjFile.Writeline dataLine
            Debug.Print dataLine
        End If

    Wend

    ObjFile.Close
    Set fso = Nothing
    Set ObjFile = Nothing

End Sub

想只返回带有传递和失败字符串的行，并将其写入另一个日志文件（sim_results）

当使用Line Input读取文件时，您必须考虑到线路输入仅在读取CR或CR和LF时停止，但在它仅读取LF时不会停止。在您的情况下，您需要将LF转换为CR和LF。你可以用Notpad ++做到这一点

由于您已经使用FSO，您也可以使用它来读取这样的文件。那你就不用担心“Unix”了。

Sub generate_sim_results()

Dim testResults As String
Dim InputFile As String
Dim fso As Object
Dim ObjFile As Object
Dim fnum As Long
Dim dataLine As String
    Set fso = CreateObject("Scripting.FileSystemObject")


    testResults = Application.ActiveWorkbook.Path & "\sim_results.log"
    If Len(Dir$(testResults)) > 0 Then
        Kill testResults
    End If


    InputFile = Dir(Application.ActiveWorkbook.Path & "\" & "*.log")
    InputFile = Application.ActiveWorkbook.Path & "\" & InputFile
    'Debug.Print InputFile

    fnum = FreeFile()
    Open InputFile For Input As #fnum
    Set ObjFile = fso.CreateTextFile(testResults)

    Dim myFile
    Set myFile = fso.OpenTextFile(InputFile, 1)
    Do While myFile.AtEndOfStream <> True
        dataLine = myFile.ReadLine
        If InStr(1, dataLine, "passed", vbTextCompare) > 0 Or InStr(1, dataLine, "failed", vbTextCompare) > 0 Then
            ObjFile.Writeline dataLine
            Debug.Print dataLine
        End If

    Loop
    myFile.Close
    ObjFile.Close
    Set fso = Nothing
    Set ObjFile = Nothing

End Sub
