Got this code, which works fine in FF3 - it dynamically redraws a menu
from user input.
####
function so_clearInnerHTML(obj) {
// so long as obj has children, remove them
while(obj.firstChild) obj.removeChild(obj.firstChild);
} - this just for info - ignore that there is no function around the next
bit!

if (httpRequest.status == 200) {
var xmldoc = httpRequest.responseXML;
//var objNodeList;
//objNodeList = xmldoc.getElementsByTagName
('systemname');
so_clearInnerHTML(document.getElementById
("systemslist"));

// loop through the returned xml list for entries and
append them back to the div
var x = 0;
while (xmldoc.getElementsByTagName('systemname')[x]) {
//alert('counted['+i+']');
var sysname = xmldoc.getElementsByTagName
('systemname')[x].childNodes[0].nodeValue;
var sysid = xmldoc.getElementsByTagName('systemid')
[x].childNodes[0].nodeValue;
//alert('systemname['+sysname+']');
//alert('systemid['+sysid+']');
// create a DIV element, using the variable eLink as
a reference to it
eLink = document.createElement("a");
//use the setAttribute method to assign it an id
eLink.setAttribute("href","findsystem.asp?
systemid="+sysid);
// add the text from 'systemname' to the anchor
element
eLink.appendChild(document.createTextNode
(xmldoc.getElementsByTagName('systemname')[x].childNodes[0].nodeValue));
// append your newly created element to an already
existing element.
document.getElementById("systemslist").appendChild
(eLink);
eBreak = document.createElement("br");
document.getElementById("systemslist").appendChild
(eBreak);
x++;
}

} else {
alert('There was a problem with the request.');
}
####

doesn't repopulate the menu via IE6 or 7
I tried to switch the while to a for -
##
for (var i=0; i<objNodeList.length; i++) {
##
(ignore the x switch in i)

but that returns a zero length list of nodes for IE, and still works for
FF

is there another way for IE to see the existance of the node list, or do
I need to approach the looping some other way?

Is responseXML in IE populated? Make sure the server sends the XML with
HTTP response header Content-Type: application/xml (or text/xml) to
ensure that IE/MSXML populate the responseXML property.
With IE you can also check responseXML.parseError.errorCode to test
whether IE had any problems parsing the XML the server sent.

Yes - using
if (httpRequest.overrideMimeType) {
httpRequest.overrideMimeType('text/xml');
}

for all browser flavours.

However, what I hadn't thought of - an should have - was that the file-
specific header in IIS was not sending content-type:text/xml

working now fine, although getting IE to respond to the search box being
cleared is another matter...

With IE overrideMimeType is not supported so the above does not help for IE.

Oh, so this is a bit irrelevant... OK

Within the same context, sort of, does IE not detect 'backspace' keys with
onkeypress? With FF, I can delete the input field and Ajax responds, but IE
just ignores this, until I type another search string in.
