Hello I am attempting to parse multiple lines of text from a text file using regexpressions. I am using vb.net with visual studio 2008.
At the moment I am filling my datatable with the text file information and am able to return each line of text and parse the first set of numbers that I am attempting to break up. I have multiple string with varying lengths of character lengths and numeric lengths however the delimiters are sometimes different. Sometimes will be whitespace and sometimes will be whitespace and chars. But is always 2 spaces.
Here is my code:
Dim myTbl As New DataTable("table")
myTbl.Columns.Add("full path", GetType(String))
myTbl.Columns.Add("number1", GetType(String))
Dim Reader As System.IO.StreamReader = New System.IO.StreamReader(_strFile)
Dim Line As String
Dim drow As DataRow
Dim numberFormat1 As String = "^([0-9]{2}-)[0-9]{1}-[0-9]{2}\s*"
Do
Line = Reader.ReadLine
If Line Is Nothing Then
Exit Do
End If
LineMod = Line.Remove(0, 3)
Dim myMatch1 As System.Text.RegularExpressions.Match = System.Text.RegularExpressions.Regex.Match(LineMod, numberFormat1)
If myMatch1.Success Then
number1 = myMatch1.ToString
Else
number1 = String.Empty
End If
Dim sAry As String() = LineMod.Split()
Dim PAry As String() = number1.Split()
drow = myTbl.NewRow
drow(0) = SAry(0)
drow(1) = PAry(0)
myTbl.Rows.Add(drow)
Loop
Reader.Close()This number format I have declared can possibly occur more than once in each line and will always be consistent. It will always be seperated by 2 white space or alpha-character and will always appear at the beginning of the line. How can I have my code check to see if the number format occurs more than once in a line and if so add it to my datatable in a new row.
