I am having a <div> with <a>s and <div>s inside it.
I am trying to read in all the elements in the right order.
With mydiv.getElementsByTagName("a") I can get the elements of a specific
tag like "a", but I want all types.
I tried getChildNodes but that doesn't seem to be widely supported.
childNodes[] seemed to do something but I couldn't get it working when I
wanted to browse through the elements.
What is the best way to do this?
A related question. If I have an element, how can I see which type (a, div,
input,etc) it is?
Thanks,

Probably because it doesn't exist. It's not part of Microsoft's DOM, or
the standardised W3C DOM (unless it's in Level 3).

Mind showing what you were trying to do? The childNodes collection is your
best bet.

Use the nodeName property. This will return a case-sensitive string with
the element name. In HTML, the string will always be in uppercase.
Hope that helps,
Mike

To help you out, childNodes returns a collection,
you can do something like:
var a = document.getElementById('aDiv').childNodes;
for (var i=0; i<a.length; ++i) {
// do something to each child
}
Other useful methods are firstChild and nextSibling - which is
really useful if you start at some unknown point in a DOM and
just want the next sibling. Say you want to find the next one
after "a" above without having to find the parentNode, work out
the index of "a", then get the next one. It's all
done by "var b = a.nextSibling". A related question. If I have an element, how can I see which type (a, div, input,etc) it is?
Use the nodeName property. This will return a case-sensitive string with the element name. In HTML, the string will always be in uppercase.
There is also nodeType, but different browsers seem to put
different node types in some places so it may not be that
useful for you.
Cheers, Fred.

The nodeType property doesn't return the information the OP wanted,
though. It returns quite literally the type: element, comment, DOCTYPE,
text, etc. However, that information does prove very useful when iterating
through the tree when looking for generic types. If you're looking for a
specific element, such as an INPUT, there isn't much need for it.
