load XML file, works in IE but no in Firefox

[SM]

Hello,

I wrote a Javascript function that loads a xml file to access the
data. After the loading of the xml file, the function init() is called
(for testing purposes im only returning the number of elements)
The loading executes ok for IE and the init() function returns the
correct numbers of elements.

When i try to load the xml file in Firefox, the init() function
executes but the number of elements is always 0. I guess is because
Firefox can't read the xml correctly. But why?

I've try rewriting the code in all the ways possible with no success.
What's wrong with this simple?

Need help
Marco
function loadXML()
{

//For firefox and friends
if (document.imple mentation && document.implem entation.create Document)
{
alert('my name is Firefox');
xmlDoc = document.implem entation.create Document("", "", null);
xmlDoc.onload = init();
}

else if (window.ActiveX Object)
{
alert('my name is IE');
xmlDoc = new ActiveXObject(" Microsoft.XMLDO M");
xmlDoc.onreadys tatechange = function () {
if (xmlDoc.readySt ate == 4)
{
try { init(); }
catch(e) {alert('Error loading the XML file: ' + e.toString()); }
}};

} //end if

else
{
alert('i have no name :(');
alert('Your browser can\'t load the XML file: ' + e.toString());
return;
} //end else if
xmlDoc.load("DB/discography_ori ginal.xml");
}
function init()
{
...
var cdElems = xmlDoc.getEleme ntsByTagName('c d');
alert('# of CDs: ' + cdElems.length) ;
...
}

I don't know if it's related but with FF it's important that the web server
gives the right mime type for XML/XSL file ( text/xml ). IE doesn't care
but for FF it's important.

I have a book that covers JavaScript and a little bit of XML. It says
that accessing XML with JavaScript _only_ works in Internet Explorer
5.0+ for Windows.

One generally uses PHP to access XML, because PHP is implemented on
the server and therefor consistent.

That line needs to be
xmlDoc.onload = init;

xmldoc.onload = init; WORKS fine
but
xmldoc.onload = init(parameters ) doesn't work!

Then the book would be wrong, which should tell you a great deal about
the rest of the book. For instance, this question was answered and fixed
in a post after yours.

Works like a charm! Thanks Martin
Although, im not sure what the evt means in function(evt). If its not
to much to ask, could you explain.
I wrote the function with and without the 'evt', and they both work
ok....just wondering

ie
xmldoc.onload = function(evt) { init(value); };
xmldoc.onload = function() { init(value); };

Thanks
Marco

Event handlers like onload have an event object argument that allows you
to check properties of the event. If you don't need that argument then
you can code
xmldoc.onload = function () {
init(value);
};
