Say I have an XML string that looks something like this:
<users>
<user>
<option value="foo">bar</option>
<option value="foo2">bar2</option>
</user>
<user2>
<option value="foo">bar</option>
<option value="foo2">bar2</option>
</user2>
</users>
I can load this into an XML doc on IE like this:
txt = ... // xml string
xmlDoc = new ActiveXObject("Microsoft.X
xmlDoc.async = false;
xmlDoc.loadXML(txt);
On Firefox, like this:
var parser = new DOMParser();
xmlDoc = parser.parseFromString(txt
So far, everything is good.
When I want to extract parts of the document, on IE I can do this:
xmlObjs = xmlDoc.getElementsByTagNam
This gives me a collection of the two options under user.
However, it does not work on Firefox - I get nothing.
I can do this:
xmlObjs = xmlDoc.getElementsByTagNam
but this gives me 4 nodes - two under user, and two under user2.
I could do this:
xmlObjs = xmlDoc.getElementsByTagNam
and walk the children looking for those nodes with a value of "option", but this takes a lot more code.
How do I do
xmlObjs = xmlDoc.getElementsByTagNam
in Firefox? I am converting a large web app to be able to run on both IE and Firefox, and the above line is in many places, I'm trying to minimize the changes I have to make.
Thanks.

>>var optionNodes = xmlDoc.getElementsByTagNam
Actually not correct, since this will get "user/anynodelist/option",
The MS implementation is actually equivalent to selectNodes(".//name"), ie selectNodes(".//user/optio
For XPATH in FireFox look at https://developer.mozilla.
PS: You might try using sarissa (http://dev.abiss.gr/saris
@BigRat - that is correct, and thanks for the extra info. Helpful to me too!
wayside, another option if you can, is to use jQuery (www.jquery.com). Not only will it simplify your loading of the XML, but it gives you a lot more options for traversing and selecting nodes in your XML object.
For example, with jQuery, you can do the following - which will give you exactly what you want:
var options = $("user>option");
Hope that helps.

I believe the getElementsByTagName is supposed to only work on a single tag name, and that IE is actually doing something it technically shouldn't.
To get around this, you can first grab the user node, and then grab it's child nodes as follows:
var optionNodes = xmlDoc.getElementsByTagNam
Hope that helps.
