Fork AJax returning XML doc
Mwalimu Gini
Is it possible to return the ajax request in Fork ajax as an xml doc.
the we we can do normally on ajax. coz i have tried tweaking it in
vain. it just returns it as string not a xml doc that can be accessed
as a DOM. any help would be appreciated. thanx in advance.

perhaps you have something like this
on200: function(xhr) {
someFunction(xhr.responseText);
}
To access the responseXML you should be able to do
on200: function(xhr) {
someFunction(xhr.responseXML);
}
I have never used this however as I use JSON as my transport format.

The xhr object sent to the callback functions of a Fork Ajax request
is just a regular browser xhr object. It is not wrapped or anything
special. For this reason I think the question is not actually
Fork-specific but rather a general xhr/xml question. Are you sure your
xml document is truly a valid xml document?

ok, this is what is returned by the forkajax
<?xml version="1.0" encoding="ISO-8859-1"?>
<gallery>
<gxml_id>id_less</gxml_id>
<gxml_ownerid>God Father</gxml_ownerid>
<gxml_name>Antoine</gxml_name>
<gxml_share>Hustlenomics Inc.</gxml_share>
</gallery>
but when i try to access the document with the below js script my
firebug gives me the xmlDoc 'has no properties' error...
xmlDoc=o.responseXML;
document.getElementById("gala_id").innerHTML=
xmlDoc.getElementsByTagName("gxml_id")[0].childNodes[0].nodeValue;
document.getElementById("gala_name").innerHTML=
xmlDoc.getElementsByTagName("gxml_name")[0].childNodes[0].nodeValue;
document.getElementById("gala_share").selected=
xmlDoc.getElementsByTagName("gxml_share")
[0].childNodes[0].nodeValue;
bloew are the div's to be filled
<div id="gala_name">dummy</div>
<div id="gala_id">dummy</div>
<div id="gala_share">dummy</div>
what could be the problem?

I think you mean returned by the server.

I'm not sure. I just tried an experiment successfully.
I created a new Ruby on Rails application
$ rails xmlExpt
$ cd xmlExpt
$ mongrel_rails start xmlExpt
I edited the file xmlExpt/public/index.html to be the following
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<meta http-equiv="Content-type" content="text/html; charset=utf-8" />
<title>test page</title>
<script type="text/javascript" src="javascripts/ajax.js"></script>
<script type="text/javascript">
var go = function() {
console.log("going");
new FORK.Ajax('GET', '/some.xml', {
onComplete: function(xhr) {
console.log("returned");
console.log(xhr.responseXML);
}
});
console.log("gone");
};
</script>
</head>
<body>
<p style="font-size:500%"><a href="#"
onclick="try{go();}catch(e){console.log(e);}return false;">go</a></p>
</body>
</html>
Then I added a file xmlExpt/public/some.xml with this content.
<?xml version="1.0" encoding="ISO-8859-1"?>

I pointed my browser to http://loccalhost:3000/ and pressed the big
"go" link. When I looked in the Firebug console I could see the xml
document was returned.
Just as an extra check I ran curl to make sure the content-type header
of the xml response was correct
$ curl -I http://localhost:3000/some.xml
HTTP/1.1 200 OK
Connection: close

Content-Type: text/xml
Content-Length: 161
It looks good with "text/xml"
Please give this example a try as I have described.

returned was html so it wasnt recognized as a xml doc. Thanks again i
