XA - Save/Load AutoHotkey Arrays in XML format

Introduction

XA was written by trueski and the original source can be found here http://www.autohotkey.com/board/topic/85461-ahk-l-saveload-arrays/
(The code posted there is no longer valid due to errors caused by upgrading the forum software.)

  • XA_CleanInvalidChars() has been added to remove invalid characters in XML.
  • Added InStr(XMLText,"<?xml") and Try/Catch to prevent error when trying to read empty/faulty/non XML file (20200904)
  • Note this is for AutoHotkey UNICODE only
  • A XA version compatible with AHK v2 can be found here https://www.autohotkey.com/boards/viewtopic.php?f=6&t=72997

Usage

    XA_Save("Array", Path) ; put variable name in quotes
    XA_Load(Path)          ; the name of the variable containing the array is returned OR the value 1 in case of error 
MyArray1:={"a":"aa","b":"bb","c":"cc"}
MyArray2:=["a","b","c"]

XA_Save("MyArray1", "test1.xml") ; see 1 below
; to load use: 
; XA_Load("test1.xml")
; MsgBox % MyArray1["b"] ; shows "bb"

XA_Save("MyArray2", "test2.xml") ; see 2 below
; to load use: 
; XA_Load("test2.xml")
; MsgBox % MyArray2[2] ; shows "b"

result of test1

<?xml version="1.0" encoding="UTF-8"?>
<MyArray1>
	<a>aa</a>
	<b>bb</b>
	<c>cc</c>
</MyArray1>

result of test2

<?xml version="1.0" encoding="UTF-8"?>
<MyArray2>
	<Invalid_Name id="1" ahk="True">a</Invalid_Name>
	<Invalid_Name id="2" ahk="True">b</Invalid_Name>
	<Invalid_Name id="3" ahk="True">c</Invalid_Name>
</MyArray2>

To check for error

if (XA_Load("file.xml") = 1) ; the name of the variable containing the array is returned OR the value 1 in case of error 
	MsgBox Error loading XML file.
