XMLDocument and XMLHttpRequest ?

[Jarod]

Hey
I have something like this:
var xmlDoc=document.implementation.createDocument("", "", null);

but in opera xmlDoc.load(...) won't work, so I use:

XMLHttpRequest, and I have all needed code... let's say it works...

So I got serviceRequest.responseXML and is there a way to initialize xmlDoc
in my case ? I am asking because I have code that uses xmlDoc.load(...) in
FF and all code that's need to futher work with XML written. So this would
be comfortable for me to use xmlDoc instead of creating everything from
start.

How about
var xmlDoc = serviceRequest.responseXML;
Of course you have to put that in the onreadystatechange event handler
at the proper place after a check of e.g.
if (serviceRequest.readyState == 4)
and perhaps further checks of the HTTP status code. But once you have
responseXML you can use that as your XML document.

And of course your server has to send *.xml files with text/xml content
header otherwise this bird won't fly (AJAX still doesn't respect file
extensions and your responseXML will contain an empty string).

It is my experience that you are safest sending the Content-Type as
application/xml rather than text/xml.

First, there is no such thing as AJAX being a defined application framework
or something, so it does not make sense to state "AJAX does/not support
this or that". Second, I hope "it" never will support that: "File
extensions" are merely a Micro$~1 means to mask their ongoing inability
to support MIME/magic properly and consequently. "File extensions" do not
belong on today's Web.
