Parcing files

[tsukun03]

Hey All I am new to Autoit and I need some help parsing a file word by word. I can't seem to figure out how to use the FileReadLine together with whit stringsplit.

Here some of my code as far as trying to get this done.

$data = FileRead($file)

;_FileReadToArray($file, $aArray)

$d = _FileCountLines($file)

$array = FileReadLine($file)

MsgBox(0, "",$d)

For $i = 1 to $d

$array = FileReadLine($file , $i)

MsgBox(0, "", $array)

$line = StringSplit( $array, "")

;$split = StringSplit($line,"(\s+|\t+)")

MsgBox(0, $i, $line) ; this output is empty. I am not sure what is going on here.

Next

Is the output of FileReadLine a string?

Thanks for you help

Welcome to AutoIt and the forum!

To read a line from a file and then parse it into single words (I assume in this example that words are separated by spaces) I would use:

$aLine = FileReadLine($sFile)
$aWords = StringSplit($aLine, " ")

If you need to use more than one separator character you can use something like:

$aWords = StringSplit($aLine, " " & @Tab)

This will split at space and tab characters.

I tried that already and when I run the program in gives me white space when for each word.

The FileReadLine gives the full line of the txt file but when I try and split that line by spaces nothing is in the msgbox just white space

here is how you would use your regexp:

$atest = StringRegExp ( $line,"(w+)[s|t]?", 3 )

The String split returns an array, to view it, include this:

#include <Array.au3>
_ArrayDisplay ($atest)

FileReadLine

Read in a line of text from a previously opened text file.

FileReadLine ( "filehandle/filename" [, line] )

Parameters

filehandle/filename The handle of a file, as returned by a previous call to FileOpen. Alternatively you may use a string filename as the first parameter. line [optional] The line number to read. The first line of a text file is line 1 (not zero), last line is -1.

Return Value

Success: Returns a line of text. Special: Sets @error to -1 if end-of-file is reached. Failure: Sets @error to 1 if file not opened in read mode or other error.

You can't use MsgBox with an array (function StringSplit returns an array). Use something like:

#include <array.au3>
$aLine = FileReadLine($sFile)
$aWords = StringSplit($aLine, " ")
_ArrayDisplqy($aWords)

You can't use MsgBox with an array (function StringSplit returns an array). Use something like:

#include <array.au3>
$aLine = FileReadLine($sFile)
$aWords = StringSplit($aLine, " ")
_ArrayDisplqy($aWords)

If you really really really need someone to press a button to make it do something afterwards, you can parse it into a string then use msgbox()

$aLine = FileReadLine($sFile)
$aWords = StringSplit($aLine," ")
$sArrayOutput = ""
For $i = 1 To $aWords[0]
    $sArrayOutput&= $aWords[$i] & @CRLF
Next
msgbox(0,"",$sArrayOutput)
