Javascript var in recursive calls

[Ger]

My problem is related to this thread. I wrote an XML DOM parser. It parses the complete tree on IE, but it stops after the first downstream on FireFox, SeaMonkey and Opera. This is a simplified code that reproduces the issue:

function PrintNode(node)
{
    AddText("<b>"+node.nodeName+"</b>="+node.nodeValue+" ("+node.childNodes.length+" children)");
    if (!node.hasChildNodes) return;
    AddText("<ul>");
    var child=node.firstChild;
    do
    {
        if (ShowMsg && !confirm(Text)) return;
        AddText("<li>");
        PrintNode(child);
        AddText("</li>");
    }
    while (child=child.nextSibling);
    AddText("</ul>");
}
 

So, why is this working in IE only? Maybe you can point me to some JScript/JavaScript difference. (A JavaScript/C++ comparison would also help.)

nb. I've already found a solution that works on all browsers:

    for (var child=node.firstChild;child;child=child.nextSibling)

Welcome to The Scripts.

Try using the childNodes array as shown in this page (see the source code).
