295567 - getElementById() looks broken for XML documents

Status: VERIFIED INVALID

(Core :: XML, defect)

Description

[alexander :surkov (:asurkov)]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; ru-RU; rv:1.7.5) Gecko/20041108 Firefox/1.0 (ax)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8b) Gecko/20050217

When I specify arbitrary namespace to XML document (not xul of html namespace)
then getElementById() returns null.

In instance:

var xmlwnd=window.open(xmlurl);
window.setTimeout(function()
	{
		alert(xmlwnd.document.getElementById('user'));
	},
0);

or if I load XML document by XMLHttpRequest object then I get the same result.

requestor=new XMLHttpRequest();
requestor.open("get", url, false);
requestor.send(null);
var xmldoc=requestor.responseXML;

alert(xmldoc.getElementById('user'));

Reproducible: Always

Since you haven't included a testcase, I'm going to guess that you haven't
defined the ID in the DTD, which you need to do for arbitrary XML.

Yes. I didn't use DTD for my XML file. Can you provide a link on such XML file
with DTD?

Attachment: testcase

save xml, dtd and xul files at root of local disc C: and run xul file.

getElementById() returns null. What is wrong?

[Peter Van der Beken [:peterv]]

Your DTD is broken. Use an XML validator to check (for example
http://www.stg.brown.edu/service/xmlvalid/).

Is there a way to attach external DTD (stored in individual file) to xml file by
file or http protocol? If I can load external DTD by chrome protocol only then why?

Mozilla does not support loading external DTDs from remote sites. You should put
a small DOCTYPE section in the beginning of all your XML documents. For example:

<!DOCTYPE foo [
<!ATTLIST abc myid ID #IMPLIED>
]>
<foo>
<abc myid="someid">I can getElementById() this!</abc>
<script
xmlns="http://www.w3.org/1999/xhtml">alert(document.getElementById("someid").firstChild.nodeValue);</script>
</foo>
