Request help parsing XML reply from HTTPRequest

[Doug Miller]

I can't seem to get this reply parsed correctly. All I'm really interested in
are Package.Postage.MailService and Package.Postage.Rate. Code snippet
follows.

<?xml version="1.0" ?>
<RateV3Response>
<Package ID="1">
<ZipOrigination>46228</ZipOrigination>
<ZipDestination>62522</ZipDestination>
<Pounds>3</Pounds>
<Ounces>0</Ounces>
<Size>REGULAR</Size>
<Zone>3</Zone>
<Postage CLASSID="1">
<MailService>Priority Mail</MailService>
<Rate>5.70</Rate>
</Postage>
</Package>
</RateV3Response>

I'm encountering *no* problems sending the request, or receiving the reply --
or displaying the *entire* reply. It's getting at the individual fields that
I'm having trouble with.

Here's the relevant portion of the code. Somebody please show me what I'm
doing wrong (or failing to do, as the case may be).

TIA...

var package = new Array;
package = objSrvHTTP.responseXML.getElementsByTagName("Packa ge");

alert (package.length);
// displays 0 !! What's going on? Should be 1, shouldn't it?

alert (package.firstChild.nodeValue);
// complains that the object doesn't support this property or method

for (var i = 0; i < package.length; i++) {
// since package.length = 0, obviously the loop will do nothing

var pkg = package.item(i);
var postage = pkg.getElementsByTagName("Postage");

for (var j = 0; j < postage.length; j++) {
var pstg = postage.item(j);
var rate = pstg.getElementsByTagName("Rate");
var srvc = pstg.getElementsByTagName("MailService");
Service.innerText = srvc.item(0).firstChild.nodeValue;
Rate.innerText = rate.item(0).firstChild.nodeValue;
}
}

>You have to serve the response declared with an XML media (MIME) type in its
Content-Type header (no matter the format of its message body), or the
`responseXML' property will most certainly not work. `text/xml' is the
media type that should be declared here.

I guess this is where I'm really lost: How can I "serve the response declared
with an XML media type in its Content-Type header" when I have no control over
what comes back from the server?

Client side is IE6 / Win XP Pro SP2. I have no idea what the server side
environment is. It doesn't belong to me, I have no control over it, and I have
to take what I can get.

You could at least check it (and perhaps rule out a possible source of
your error). Get some proper debugging tools, which will display the
response's header.

Get Firefox and Firebug and then start debugging.

I'm on Windows XP Pro, using IE6 (testing this from my desktop PC before
attempting to upload to a web server).

That would explain it, then: the server is sending back no Content-Type header
*at all*.

Any suggestions on how to proceed? (Other than complaining to the server
administrator, that is.) Please note that I'm working in IE6 (not by choice,
but that's the way it is), and the overrideMimeType() method is not available.
