Parsing IRC Chat

[Cormin]

My script currently reads a text file line by line. I want it to look for this the chat message below and skip the session messages.

[10:15] <Cormin> heres my chat message

There are some garbage lines that I want it to skip over. So if a line doesnt match that format then skip it. I tried experimenting with StringRegExp but I think I'm using it wrong. Heres my code

If StringRegExp($read, '\W\d\d\w\d\d\D.\W') = Not @error Then

I was hoping that this would be able to see the open bracket, 2 digits, a colon, 2 digits,  close bracket, a space and a <. But it doesn't seem to be working.

 

Eventually I want to be able to extract the username and chat message into separate strings but I haven't got that far yet.

Local $text = StringRegExp($read2, '[:ascii:][:digit:][:digit:][:ascii:][:digit:][:digit:]]*?')

I've tried this too but it just always returns a 0 for every line that isnt blank.

Cormin,

This works for me:

#include <Array.au3>
#include <StringConstants.au3>

$aLines = FileReadToArray("IRC.txt")

_ArrayDisplay($aLines, "", Default, 8)

Global $aExtract[UBound($aLines) - 1][2]    ; Array to hold the extracted data
Global $iIndex = 0                          ; Index of array to fill
Global $sDelim = "~~~~~"                    ; Choose a string that is very unlikely to appear in the message

For $i = 0 To UBound($aLines) - 1
    ; Loop through the lines and check if they match a message line - extract the name and the message
    $sExtract = StringRegExpReplace($aLines[$i], "^.*<(\w+)>\s(.*)$", "$1" & $sDelim & "$2")
    ; Split the line
    $aSplit = StringSplit($sExtract, $sDelim, $STR_ENTIRESPLIT)
    ; Save the the array
    If Not @error Then
        $aExtract[$iIndex][0] = $aSplit[1]
        $aExtract[$iIndex][1] = $aSplit[2]
        ; Increase the index
        $iIndex += 1
    EndIf

Next

; Correctly size the extracted array and show it
ReDim $aExtract[$iIndex][2]
_ArrayDisplay($aExtract, "", Default, 8)
