I need to parse a text file so the results only show like the following:

The data.txt file I'm parsing from:

D08-10-06 10:05:27.010 XXX:390823892aw4dca: -rate(Dlr/u):15.792581 for ASDGADFSCSS:[TRUCKS->TRAILERS]
D08-10-06 10:07:28.593 XXX:390823892aw4dca: -rate(Dlr/u):94.99838 for ASDRFACSD:[TRAILERS->AIRPLANE]

Results Requested:

DLR,Rate,Method
Dlr/u,15,TRUCKS->TRAILERS
Dlr/u,94,TRAILERS->AIRPLANE

I would like to use either FindStr or some DOS method, or vbscript to parse the file. I have writen one but doesn't quite do the job.
Option Explicit 
 

Dim objFSO, objLog 

Dim strInputLog, strOutputLog, strData, strLine, strMethod, strTime 

Dim strDetail, strDlr 

Dim arrLines, arrDetail 

Dim intLength 

Dim strFnl
 

CONST ForReading = 1 
 

Set objFSO = CreateObject("Scripting.FileSystemObject") 
 

'Set path to input and output files 

strInputLog = "data.txt" 

strOutputLog = "Final_data.txt" 
 

'Open input log and create the output log 

strData = objFSO.OpenTextFile(strInputLog,ForReading).ReadAll 

Set objLog = objFSO.CreateTextFile(strOutputLog) 
 

'Split the input log into lines 

arrLines = Split(strData,vbCrLf) 
 

'Step through the input log lines and break them into 

'strings based on spaces 

For Each strLine in arrLines 

If strLine <> "" Then 

arrDetail = Split(strLine," ") 
 

'Parse through strings looking for matches, process the 

'strings and write results to output log 

For Each strDetail in arrDetail 

  intLength = LEN(strDetail) 

  If InStr(strDetail,"TRUCKS->TRAILERS") Then 

   strMethod = Right(strDetail,intLength - 78) 

ElseIf InStr(strDetail,"TRAILERS->AIRPLANE") Then 

   strMethod = Right(strDetail,intLength - 78) 

ElseIf InStr(strDetail,"TRAILERS->ROCKET") Then 

   strMethod = Right(strDetail,intLength - 78)

  ElseIf InStr(strDetail,"Dlr/u,") Then 

   strDlr = Right(strDetail,intLength - 5) 
 

strMethod = Replace(strMethod, ":", ",")

strMethod = Replace(strMethod, "[", ",")

strMethod = Replace(strMethod, "]", "")

strDlr = Replace(strDlr, ":", ",")

strDlr = Replace(strDlr, ".", ",")

strDlr = Replace(strDlr, "(", "")

strDlr = Replace(strDlr, ")", "")
 
 
 
 
 

strFnl = strDlr & "" & strMethod & "," & Date
 

strFnl = Replace(strFnl, "),,", ",")

strFnl = Replace(strFnl, ",,", ",")
 

objLog.Writeline strFnl
 
 
 

  End If

Try this out...
Option Explicit 
 

CONST ForReading = 1  
 

Dim objFSO, objLog 

Dim strInputLog, strOutputLog, strData, strLine, arrLines

Dim DLR, Rate, Method

Dim DlrTagLeft, DlrTagRight, rateTag, methodTag

Dim valuesA, valuesB, valuesC, valuesD 

 

Set objFSO = CreateObject("Scripting.FileSystemObject") 

 

'Set path to input and output files 

strInputLog = "data.txt" 

strOutputLog = "Final_data.txt" 

 

'Open input log and create the output log 

strData = objFSO.OpenTextFile(strInputLog,ForReading).ReadAll 

Set objLog = objFSO.CreateTextFile(strOutputLog) 

 

'Split the input log into lines 

arrLines = Split(strData,vbCrLf) 

 

' Sample Input Line:

' D08-10-06 10:05:27.010 XXX:390823892aw4dca: -rate(Dlr/u):15.792581 for ASDGADFSCSS:[TRUCKS->TRAILERS]
 

' Sample Output Line:

' Dlr/u,15,TRUCKS->TRAILERS
 
 

DlrTagLeft = "-rate("

DlrTagRight = "):"

rateTag = " for "

methodTag = ":["
 

For Each strLine in arrLines 

    If strLine <> "" Then

        valuesA = Split(strLine, dlrTagLeft)

        valuesB = Split(valuesA(1), dlrTagRight)

        DLR = valuesB(0)

        valuesC = Split(valuesB(1), rateTag)

        Rate = CInt(valuesC(0))

        valuesD = Split(valuesC(1), methodTag)

        Method = Left(valuesD(1), Len(valuesD(1)) - 1)

        objLog.Writeline Join(Array(DLR, Rate, Method), ",")

    End If

Next

I didn't put the column headers into the output file...  =\

Add this line:

    objLog.Writeline "DLR, Rate, Method"

Right above the "For Each" loop.

If you want a space after the comma in the data lines then change:

    objLog.Writeline Join(Array(DLR, Rate, Method), ",")

To:

    objLog.Writeline Join(Array(DLR, Rate, Method), ", ") ' <--- Space after the comma!

Thank you Idle_mind however I kept getting errors when trying to use your script. I ended up coming up with this script instead.

Const ForReading = 1

strInputLog = "data.txt"
strOutputLog = "Final_data.txt"
strSearchString1 = "dlr/"
strSearchString2 = ":["

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objInputFile = objFSO.OpenTextFile(strInputLog, ForReading)

Set objOutputFile = objFSO.CreateTextFile(strOutputLog)

Do Until objInputFile.AtEndOfStream
    strText = objInputFile.ReadLine

    strFoundString1 = Mid(strText, InStr(1, strText, strSearchString1) + 7)
    strFoundString1 = Mid(strFoundString1, 1, InStr(1, strFoundString1, " ") - 1)
   
    strFoundString2 = Mid(strText, InStr(1, strText, strSearchString2) + 2)
    strFoundString2 = Mid(strFoundString2, 1, InStr(1, strFoundString2, "]") - 1)
   
    objOutputFile.WriteLine (strFoundString1 & "," & strFoundString2 & "," & date)
Loop

objInputFile.Close
objOutputFile.Close

Set objInputFile = Nothing
Set objOutputFile = Nothing

Set objFSO = Nothing
