I've gone back to working on Interface Writer - specifically the bit that loads XML files. It's a long bit of code, so I've put it in a spoiler tag.
Spoiler:
js code:
function OnEvent_Initialize(MessengerStart)
{
var Interface = LoadInterface(MsgPlus.ScriptFilesPath + "\\" + "Windows.xml");
var JSONO = new JSON();
var JSONSource = JSONO.toJSON(Interface);
WndWriterViewSource = MsgPlus.CreateWnd("Windows.xml", "WndWriterViewSource", 0);
WndWriterViewSource.RichEdit_SetCharFormat("EdtSource", false, -1, -1, -1, -1, -1, -1, "Lucida Console");
WndWriterViewSource.SetControlText("EdtSource", "JSON Output of \"Windows.xml\"\n\n-----\n\n" + JSONSource);
}
function LoadInterface(File)
{
var XMLO = new ActiveXObject("Microsoft.XMLDOM");
var Interface = new Object();
Interface.Ok = true;
if (!XMLO.load(File))
{
Interface.Ok = false;
Interface.Error = XMLO.parseError.reason + "Line number: " + XMLO.parseError.line + " (position " + XMLO.parseError.linepos + ").";
XMLO = null;
return Interface;
}
if (XMLO.selectSingleNode("//Interfaces/Window") === null)
{
Interface.Ok = false;
Interface.Error = "The interface file must contain a root <Interfaces> tag, as well as at least one window.";
XMLO = null;
return Interface;
}
Interface.Window = new Object();
Interface.WindowId = new Array();
var WindowEnum = new Enumerator(XMLO.selectNodes("//Interfaces/Window"));
for (; !WindowEnum.atEnd(); WindowEnum.moveNext())
{
var WindowNode = WindowEnum.item();
var WindowId = WindowNode.getAttribute("Id");
Interface.WindowId.push(WindowId);
Interface.Window[WindowId] = new Object();
Interface.Window[WindowId].Control = new Object();
Interface.Window[WindowId].ControlId = new Array();
var ControlEnum = new Enumerator(XMLO.selectNodes("//Interfaces/Window[@Id=\"" + WindowId + "\"]/Controls/Control"));
if (ControlEnum.count() > 0)
{
for (; !ControlEnum.atEnd(); ControlEnum.moveNext())
{
var ControlNode = ControlEnum.item();
var ControlId = ControlNode.getAttribute("Id");
var ControlType = ControlNode.getAttribute("xsi:type");
if (ControlId in Interface.Window[WindowId].Control)
{
ErrorDialog("Warning: two controls share the name \"" + ControlId + "\" in window \"" + WindowId + "\".\nThe second occurrence of this control name will be ignored.", "Load Interface File");
}
else
{
Interface.Window[WindowId].ControlId.push(ControlId);
Interface.Window[WindowId].Control[ControlId] = new Object();
var ControlPosEnum = new Enumerator(XMLO.selectNodes("//Interfaces/Window[@Id=\"" + WindowId + "\"]/Controls/Control[@Id=\"" + ControlId + "\"]/Position"));
if (ControlPosEnum.count() == 0)
{
ErrorDialog("Warning: no position tag found for control \"" + ControlId + "\" in window \"" + WindowId + "\".", "Load Interface File");
}
else
{
Interface.Window[WindowId].Control[ControlId].Position = new Object();
for (; !ControlPosEnum.atEnd(); ControlPosEnum.moveNext())
{
var ControlPosNode = ControlPosEnum.item();
Interface.Window[WindowId].Control[ControlId].Position.Left = ControlPosNode.getAttribute("Left").toString();
Interface.Window[WindowId].Control[ControlId].Position.Top = ControlPosNode.getAttribute("Top").toString();
Interface.Window[WindowId].Control[ControlId].Position.Width = ControlPosNode.getAttribute("Width").toString();

Enumerator.prototype.count = function()

var i = 0;
while (!this.atEnd())

i++
}
this.moveFirst();
return i;
}
The highlighted line throws a type mismatch error. Using
nodeObj.getAttribute() works for something like
<Tag Value="String"/>, but I want to get something like
<Tag>String</Tag>. How would I go about this, since I only just understand the basics of the XML DOM object...
