[Xerte] Xerte and Flash security

I never got the difference, unless it's the <req> thing?

So it is legal XML but AS2 doesn't support all characters when access is made via dot notation.
Brilliant!

The workaround is to wrap the offending phrase in []

This works:
ctrls.templateData.ok[0]["correct-tasks"][0].task[0].desc));

Sheesh.

Still don't know why sendAndLoad won't work from the server, but LoadVars will.

According to "XML for the World Wide Web" by Elizabeth Castro, hyphens can be used in element names, but element names cannot begin with them. Element names must begin with a letter, and underscore, or a colon; and cannot begin with the letters x, m and l in either upper or lowercase.

Pat, see my post about having been down this road.

All this thrashing about is due to the fluky chance that a client sent me some XML to test with a hyphen in an element tag.
Hyphens are perfectly XML legal AFAIK.
I kept getting NaN back when I tried to access via dot notation anything  within that tag set.

Now the easy answer is of course, change the tag. But when you do dynamic engines and don't know in the long run what someone might try to run through there, it can't be considered best practice ;-)

So I thought, OK, maybe the XML has to come URL encoded, and using FileLocation doesn't give me that.
So I tried to serve the XML off my server, and now I've run into the sendAndLoad vs Loadvars problem.

Anyway, I tested in a dummy file using Loadvars to the XML on my server, and elements with a hyphen still return NaN when access is attempted.

Think xerte desktop still uses IE to get to the internet?

Thought that only operated on a browser.
I'm in Xerte desktop.

"ctrls.sendAndLoad(myReq, 'http://www.myserver.com/dave/some.xml'); // just sits at event trap"

Using the full domain in the http:// request?

Only works on domains I think.
Never seen a local file system specified in one.

If while I am developing a bit and I want to load some XML from my server, what's the trick?

ctrls.sendAndLoad(myReq, FileLocation + 'some.xml'); //trips onLoad event

ctrls.sendAndLoad(myReq, 'http://www.myserver.com/dave/some.xml'); // just sits at event trap
