Question

I have a text file that has multiple blank lines and Im trying to return all the lines between two of them specifically

so if I have a file that looks like this:

 ____________________________
 1########################
 2##########################
 3
 4########################
 5##########################
 6#######################
 7
 8#########################
 9##########################
 10#######################
 11####################
 12########################
 13#########################
 14
 15##########################
 ----------------------------

I would like to grab lines 8-13. Unfortunately, it might not always be 8-13 as it could be 9-20 or 7-8, but it will however always be between the 2nd and 3rd line break.

I know how to trim characters and pull out singular lines, but I have no idea how to trim entire sections.

Any help would be appreciated, even if you just point me to a tutorial.

Thanks in advance.

Answer 1

What I ended up doing was trimming the last part and searching for what I needed in the first part (I know I didnt include the searching part in the question, but I was just trying to figure out a way to narrow down the search results as it would have had repeated results). Im posting this incase anyone else stumbles upon this looking for some answers.

Dim applist() = System.IO.File.ReadAllLines("C:\applist.txt")
Dim findICSName As String = "pid"
Dim ICSName As New Regex("\:.*?\(")
Dim x = 0
    Do Until applist(x).Contains("Total PSS by OOM adjustment:")
        If applist(x).Contains(findICSName) Then
            app = ICSName.Match(applist(x)).Value
            app = app.TrimStart(CChar(": "))
            app = app.TrimEnd(CChar("("))
            ListBox1.Items.Add(app)
        End If
        x = x + 1
    Loop
End If

How this works is that it looks through each line for the regex until it reaches first word in the breakpoint “Total PSS by OOM adjustment:”
