Reading Array to Columns

7 posts in this topic

#1 ·  Posted (edited)

I have a text file with 800 lines. I need to search for a particular Heat Number [which in the array will be Column 18]. I can get somewhat of a 2d display of the array, but I can't figure out how to break up the text file first so that each field is in a column. Here is what I have so far:

this text file is called: Heatlist.txt

M;P;Eddie;Jones;;;34;F;A;Ann;Year;;;4294967295;Academy Ballroom;5;12/04/2010 23:38;Heat 306;Superstars;CC/R/SW/B/M;Open;C;1;

M;P;Phillip;Darley;;;42;F;A;Jane;Richards;;;4294967295;Darley's Ballroom;5;12/04/2010 23:38;Heat 306;Superstars;CC/R/SW/B/M;Open;C;4;

M;P;Phillip;Darley;;;42;F;P;Mary;Strayer;;;4294967295;Darley's Ballroom;5;12/05/2010 00:10;Pro heat 2;Professional Showdance;;;;1;

#include "array.au3"

#include "File.au3"

#include "Date.au3"

#include "String.au3"

_FileReadToArray("C:\cmp\heatlist.txt",$aResult)

_ArrayDisplay($aResult,"Test")

For $iIndex = 1 To $aResult[0]

If StringInStr($aResult[$iIndex], "Heat 306") Then

MsgBox(4096,"Yes!","r")

EndIf

Next

I can get all the records to display, but all the data is in Column 0. Where am I going wrong?

Might have something to do with how each line is broken in the original heatlist.txt file. I copied and pasted the text you provided into notepad then ran the script and it worked fine for me...

The _FileReadToArray() reads each entire line into a single element of a 1D array. Look for the various examples posted to read CSV files into a 2D array, some have user-specified delimiter so you can set ";" vice ",".

But...how can it put each piece of data for each record when we have not told it what the seperator [the ;] is?

I get an array of all the records, but each record of data is all in Column 0, not seperated into columns by the ; delimiter.

I agree...but I have not been able to find one yet via my search of this forum...

You could use something like this:

$File = FileOpen("C:\cmp\heatlist.txt", 0)
While 1
     $ReadLine = FileReadLine($File) ; Reads in one line of the file at a time
     If @error then ExitLoop  ; if it got to the end of the file exit the while loop
     $Array = StringSplit($ReadLine, ";") ; splits the read line using the ";" as the place to split each element
     ;<do what you need to do with the array contents here>
