VBA Macro : catch a line with specific string and return it


im trying to catch simulation results from a simulation report (.log).I want to match "passed" and "failed" strings and to save the line where the match were done in an other results file that i will use for further operations in excel. I couldn't match the desired lines: the following sub that i wrote writes not only the desired lines but all the lines. i dont know where the problem is..

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

*sample of the log file*
<time="1500 ns" instance="testcase_00">passed
<time="342100480 ps" instance="testcase_01">passed
blabla informations about the tests....
<time="742894 ns" instance="testcase_02_01">passed

want to return only the lines with the passed and failed strings and write it in another log file (sim_results)


Solution

  • When reading a file with Line Input you have to take into consideration that Line Input will only stop when it reads a CR or a CR and LF but it will not stop in case it only reads a LF. In your case you need to convert th LFs to a CR and LF. You can do that with Notpad++

    As you already use FSO you could also use it to read the file like this. Then you do not need to bother about "Unix".

    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
