Hello Folks:
I'm running Apache 2.2.15 on Solaris. This system is for, among other things, developing code that I'll move to my web site, on a hosting service.
Should I upgrade Apache? I intend to upgrade eventually, but I have other priorities right now.
I can't get XMLHttpRequest.responseXML to work.
The code works on my hosted web site, but fails on my system. So I'm guessing there is something wrong with my Apache setup.
This seems to work:
| Code: |
xmlDoc=xmlhttp.responseXML;
|
And this seems to work:
| Code: |
xmlhttp.open("GET","note.xml",false);
xmlhttp.send();
|
Because this seems to work:
| Code: |
document.getElementById("response").innerHTML = xmlhttp.response;
document.getElementById("response_text").innerHTML = xmlhttp.response;
|
Text from the XML file are brought over to the HTML from the server. That's a nice feature.
But this fails on my server:
| Code: |
xmlDoc=xmlhttp.responseXML;
|
responseXML has a vale of NULL.
responseXML has a proper XML DOM when the same code with the same XML file is run on my hosted web site.
So I must not have Apache set up properly.
I'm suspecting something wrong with mime.types.
Here is the HTML code that works on my hosted web site, but fails on my system:
| Code: |
<!DOCTYPE html>
<html>
<body>
<h3>Test of XMLHttpRequest.responseXML</h3>
<div>
<br />
Response HTML:
<p id = "response_html"> </p>
<br />
Response:
<p id = "response"> </p>
<br />
Response Text:
<p id = "response_text"></p>
</div>
<script>
var error_message;
try
{
if (window.XMLHttpRequest)
{
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{
// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET","note.xml",false);
xmlhttp.send();
document.getElementById("response").innerHTML = xmlhttp.response;
document.getElementById("response_text").innerHTML = xmlhttp.response;
xmlDoc=xmlhttp.responseXML;
document.getElementById("response_html").innerHTML=
xmlDoc.getElementsByTagName("to")[0].childNodes[0].nodeValue;
}
catch(err)
{
error_message = "Error \n";
error_message += err.message;
alert(error_message);
}
</script>
</body>
</html>
|
Here is the XML:
| Code: |
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>
|
Suggestions?
Thanks

For me the code works fine. Are you sure your server send the correct mime type / Content-Type application/xml for the note.xml ?
However I recommend to install firebug in firefox and find the error.
Not all browsers support xmlhttp.responseXML. That is why I use jQuery as framework which chooses the right method. |

Thanks James:
Yea, I thought this was an Apache configuration issue.
That's why I posted it to the Apache forum. It was moved here, where I don't believe Apache Configuration is on topic.
If Apache is not configured to deliver XML to the script, not delivering it is probably not a bug or a problem.
Do you have any idea what httpd.conf or mime.types entry would enable, or disable, the delivery of the XML tree to the script?
Both FireFox and Chrome have the XML DOM tree when connected to my hosted web site, and have NULL when connected to my test site.
I appreciate your efforts.
Thanks
