How to pass URL to UrlRequest properly in AS3?

Question

I have a file abc.swf embed in a html file called index.html

The SWF file needs to access abc.xml

The abc.xml is stored in Rooms/abc.xml

The index.html is stored in Schedule/index.html

In the abc.swf, I have code:

inforequest=new URLRequest("~/Rooms/abc.xml");

However I got an error:

Error #2044: Unhandled ioError:. text=Error #2032: Stream Error

I know this is because the URL is wrong but I dont know how to fix that. I've tried: Rooms/abc.xml, abc.xml, ../Rooms/abc.xml but none of them worked. Please help!

EDIT:

This is the html file:

@model Booking_Ticket_Management_System.Models.Schedule

@{
ViewBag.Title = "XmlGenerate";
}

<h2>Choose your seats</h2>
<object width="500" height="600">
<param name="movie" value="~/Rooms/@Url.Content(Model.Room.Map)"/>
<embed src="~/Rooms/@Url.Content(Model.Room.Map)" width="500" height="600"/>
</object>

Answer 1

Get into habit to always add at least 2 listeners: Complete - which normally is added by all, and IOErrorEvent which normally is skipped by all:)

var loader:Loader = new Loader();

    loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaderHandler, false, 0, true);
    loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, loaderHandler, false, 0, true);

    loader.load(new URLRequest("path/to/image.jpg"));

//...
protected function libLoadHandler(e:Event):void 
{
    var loader:Loader = (e.target as LoaderInfo).loader;
    if(e.type == Event.COMPLETE || e.type == IOErrorEvent.IO_ERROR)
    {
        //unregister both as COMPLETE and IO_ERROR are "finishing" events
        loader.contentLoaderInfo.removeEventListener(Event.COMPLETE, loaderHandler, false);
        loader.contentLoaderInfo.removeEventListener(IOErrorEvent.IO_ERROR, loaderdHandler, false);

        //do something after event based on event type
    }
}

try this,

var myRequest:URLRequest = new URLRequest("../abc.xml");
