有.innerXML吗？

i'd like to ask if anyone here is familiar wif xml who can give me some help... http://www.plognow.com/xml/login.xml and i hv a little function tht i use to break it up...

function dialogXML(varName,url){
    if (window.XMLHttpRequest){
        r[varName]=new XMLHttpRequest();
    }else{
        r[varName]=new ActiveXObject("Microsoft.XMLHTTP");
    }
    r[varName].onreadystatechange=function(){
        if (r[varName].readyState==4 && r[varName].status==200){
            var rep=r[varName].responseXML.getElementsByTagName('box')[0];
            var title=rep.getElementsByTagName('title')[0].nodeValue;
            var content=rep.getElementsByTagName('content')[0].nodeValue;
            createDialog(title,content);
        }
    }
    r[varName].open('GET',url,true);
    r[varName].send();
}

well i'm not sure how XMLDOM works, but can i retrieve the inwards of one tag?(all the childs subchilds etc)like u'd do in innerHTML. thanks!

You can use jQuery to manipulate XML documents as well not just HTML documents. HTML documents are XML documents.

if (r[varName].readyState==4 && r[varName].status==200){
    var xml = r[varName].responseXML;            
    var rep = $("box:first", xml);
    var title = $("title:first", rep).text();
    var content= $("content:first", rep).text();
    createDialog(title, content);
}

If your question is how to retrieve xml tree structure then the answer is : using responseXML property of r[varName].
