I'm a bit late to the party, but...

This script will return all the sections, entries and values as an array that you can enumerate.

It also returns all the bad sections and entries, including malformed sections and entries with no values.

Code:
$=SetOption("Explicit","ON")
 
Dim $sIniFile,$asIniCollection,$asIniItem
 
$sIniFile="\path\to\myinifile.ini"
 
$asIniCollection=EnumIni($sIniFile)
For Each $asIniItem in $asIniCollection
	?
	"Section: '" $asIniItem[0] "'" ?
	"Key    : '" $asIniItem[1] "'" ?
	"Value  : '" $asIniItem[2] "'" ?
Next
 
Function EnumIni($sIniFile)
	Dim $fd,$sLine
	Dim $aEntry[3]
	$fd=FreeFileHandle()
	If @ERROR Exit @ERROR EndIf
	If Open($fd,$sIniFile) Exit @ERROR EndIf
	$sLine=ReadLine($fd)
	While Not @ERROR
		$sLine=LTrim($sLine)
		If $sLine<>"" AND Left($sLine,1)<>";"
			$aEntry[1]=""
			$aEntry[2]=""
			If Left($sLine,1)="["
				$aEntry[0]=SubStr($sLine,2,InStr($sLine+"]","]")-2)
			Else
				$aEntry[1]=Left($sLine,InStr($sLine+"=","=")-1)
				$aEntry[2]=SubStr($sLine,Len($aEntry[1])+2)
				Redim Preserve $EnumIni[UBound($EnumIni)+1]
				$EnumIni[UBound($Enumini)]=$aEntry
			EndIf
		EndIf
		$sLine=ReadLine($fd)
	Loop
EndFunction
