My Javascript wont read my xml

[catronro]

I want to read an xml file and build a string based on that file. But
when i try to implement it i get an Object Required error. Any help
would be greatly appreciated.

try
{
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
var html = "";
xmlDoc.load('siteMap.xml');
var xmlObj=xmlDoc.documentElement;
alert(xmlObj.xml);

for(var i=0; i < xmlObj.childNodes.length; i++)
{
var path = xmlObj.childNodes(i).getAttribute("address");
var name = xmlObj.childNodes(i).firstChild.text;
html += "<a href='" +path+ "'>"+name+"</a> &nbsp;
&nbsp;";
}
document.write(html);

}
catch(err)
{
alert(err.description);
}

This is the file im trying to read in

<?xml version="1.0" encoding="utf-8" ?>
<mainSiteMap>
<siteMap address="home.htm">HOME</siteMap>
<siteMap address="events.htm">EVENTS</siteMap>
<siteMap address="contacts.htm">CONTACTS</siteMap>
<siteMap address="albums.htm">ALBUMS</siteMap>
<siteMap address="register.htm">REGISTER</siteMap>
</mainSiteMap>

This is how i call the javascript in my HTML file

<script type="text/javascript" src="Code/Javascript.js"></script>

When do you get the error? Do you get the XML file OK, or does it bomb
before then?

try
{
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");

Do you want this to work in browsers other than those that support
Microsoft's proprietary ActiveX?

var html = "";
xmlDoc.load('siteMap.xml');
var xmlObj=xmlDoc.documentElement;
alert(xmlObj.xml);

What happens here? What does the alert show?

for(var i=0; i < xmlObj.childNodes.length; i++)
{
var path = xmlObj.childNodes(i).getAttribute("address");
var name = xmlObj.childNodes(i).firstChild.text;
html += "<a href='" +path+ "'>"+name+"</a> &nbsp;
&nbsp;";
}
document.write(html);

If you are doing this just to generate a simple menu, it's likely the
worst way of going about it.

}
catch(err)
{
alert(err.description);

What happens here?

}

<siteMap address="register.htm">REGISTER</siteMap>
</mainSiteMap>

Why not use the server to generate HTML from the XML and serve that
directly to the client? Using client scripting to munge XML into HTML
for a simple menu is just asking for trouble - you could do it on the
server with XSLT and get a far more reliable result.

If you want to use XMLHttpRequest, use a library like that provided at:

<URL:http://www.ajaxtoolbox.com/>

If you don't want all the functionality, strip out what you don't want.
IE 7 supports XMLHttpRequest (apparently, I haven't tested it),
hopefully ajaxtoolbox will not need any changes in that regard while
still supporting older IE and W3C browsers.

var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
var html = "";
xmlDoc.load('siteMap.xml');

You need at least
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = false;
if (xmlDoc.load('siteMap.xml')) {
// how you can process/access the DOM here
}
else {
// deal with parse error e.g.
alert(xmlDoc.parseError.reason);
}

In the end however using synchronous requests is not a good idea as it
blocks the complete browser so doing
xmlDoc.async = true;
and processing the XML in an onreadystatechange handler is a better idea.
To go cross browser you might prefer to use XMLHttpRequest, see
