Hi there!
I'm trying to figure out how to traverse an xml hierarchy from within
javascript.
Here's my text.xml file:
<?xml version="1.0" encoding="ISO-8859-1"?>
<main>
<text1>this is a text</text1>
<text2>this is another one</text2>
<text3>and this is the last</text3>
</main>
And here's the xhtml/javascript code I've written. It's supposed to be
viewed in mozilla/firefox (now I want a working function, then I'll
think about cross-browsing stuff), and it doesn't work as I expected:
<html>
<title>temp</title>
<head>
<script name="text/javascript">
<!--
var xml_dom = null;
window.onload=f unction() {
xml_dom = document.implem entation.create Document("", "", null);
xml_dom.load("t ext.xml");
xml_dom.onload= parse_xml;
}
function parse_xml() {
var xml_parser = new DOMParser();
xml_dom = xml_parser.pars eFromString("<m ain>", "text/xml");
var nodes = xml_dom.documen tElement.childN odes;
alert(nodes.len gth); // this say "2", but it should be "3"...why?? ?
for (var i=0; i < nodes.length; i++) {
document.write( nodes[i].nodeValue);
}
}
//-->
</script>
</head>
<body>
</body>
</html>
What am I doing wrong??
Thanks,
shinya

Also whats the DOMParser object? I don't know wanything about nodes
and the likes.

No, E4X is not a W3C standard, it is an ECMA standard and currently on
its way to an ISO standard.
But E4X as specified and implemented in Firefox 1.5 does not help to
load and parse XML from a URL.
You can only build XML objects natively or parse from string. Hopefully
the next major new Firefox release will have DOM <--> E4X integration
but so far there is no such integration.
http://www.w3schools.com/e4x/default.asp
That claims that
var xmlDoc=new XML()
xmlDoc.load("no te.xml")
is (possible with) E4X but that is nonsense, the XML objects in E4X do
not have any method named load.

Why are you reassigning xml_dom?
var nodes = xml_dom.documen tElement.childN odes;
alert(nodes.len gth); // this say "2", but it should be "3"...why?? ?
for (var i=0; i < nodes.length; i++) {

Hi all
I've written a class that will traverse a folder and its subfolders for

recursive call to a method I call "Traverse", but I saw somewhere
in the newsgroups, that there is a way, that will make use of Windows's
Indexing Service. I just wasn't able to figure out how though.
As this is my first try on C#, I would really like some input on my

Using vs 2003, vb.net
It is not clear from the documentation, but it appears that a raised event
will traverse up the call stack upwards until it reaches its handler. Is
this correct? See the code snippet below. The event raised in sub1 or
class three will be caught in Class1 event handler (I know below is not
syntactically correct, but you get the idea).

Hi, i've been trying to investigate how to traverse through an object
instance properties or fields with no success. I have read about
IEnumerable interface but that seems to apply only to collection of
objects. What i want to do actually is to traverse through each
property of an instance and if possible, assign a null value...
something like this:
MyClass instance = new MyClass();
instance.property1 = "A string";

Hi!
I'm looking for a way to traverse all the controls on a dialog in the
order of the tabstop index. Note that I use unmanaged C++, so no
GetTabIndex function afaik.
The ALMOST perfect function for this looks like:
CWnd::GetNextDlgTabItem.
BUT...this function skips controls that are disabled (WS_DISABLED),
