Checking when Microsoft.XMLDOM is done with XML import?

[jfizer]

I have a web app that uses a form with its fields populated from XML
using Microsoft.XMLDO M. The problem is that Microsoft.XMLDO M functions
seem to run on their own thread, so I dont know when the fields are
done populating.

Can anyone think of a way for me to check when the following function
finishes?

function importXML(xmlQu ery,xmlSrc,xmlT arget)
{
var xmlDoc = new ActiveXObject(" Microsoft.XMLDO M");
xmlDoc.onreadys tatechange = function () {
if (xmlDoc.readySt ate == 4)
parseXML(xmlQue ry,xmlSrc,xmlTa rget,xmlDoc)
};


xmlDoc.load("ht tp://home1/sandbox/XMLResponder.ns f/XMLResponder?op enagent&frm="+
xmlSrc +"&z=.xml");
return true;
}

function parseXML(xmlQue ry,xmlSrc,xmlTa rget,xmlDoc)
{
var x = xmlDoc.getEleme ntsByTagName('f ield');
var sValue;
var sText;
for (i=0;i<x.length ;i++)
{
var row = document.create Element('TR');
for (j=0;j<x[i].childNodes.len gth;j++)
{
if (x[i].childNodes[j].nodeType != 1)
continue;
sValue =
x[i].childNodes[j].firstChild.nod eValue;
j++;
sText =
x[i].childNodes[j].firstChild.nod eValue
addOption(xmlTa rget,sText,sVal ue);
}
}
}

The XML document is loaded when xmlDoc.readySta te == 4 and the fields
are populated when the parseXML function finishes.

I am aware of this, however my problem is as follows.

I have four select lists. The user can select items from list A and
add or delete them from list B. Depending on whats in list B, list C
gets populated via XML. The user can then select items from list C and
add or remove them from list D. The problem is when there are items in
list D and the user then removes an item from list B. This means that
list C changes and I need to make sure that the selected items that
got inserted into list D are still in list C. I've not been able to
find a way to do this because I dont know when list C is done being
populated.
