关于网页提示警告[object XMLDocument]

Question

今天在用ajax读取xml时报这个警告，有大神知道怎么处理吗？，部分源码在下面了

servlet源码

        response.setContentType("text/XML;charset=UTF-8");
        PrintWriter out = response.getWriter();
        HashMap<String, String> map = new HashMap<String, String>();
        map.put("a", "<words><word>a</word><word>ab</word><word>abc</word></words>");
        map.put("ab", "<words><word>ab</word><word>abc</word><word>abcd</word></words>");
        String inputWord = request.getParameter("inputWord");
        if(!map.containsKey(inputWord)) {
            out.println("<words></words>");

js源码

function display() {
        if(httpRequest.readyState == 4){
            if(httpRequest.status == 200){
                var xmlDoc = httpRequest.responseXML;
                clearDivData();
                alert(xmlDoc);
                changeDivData(xmlDoc);
            }else{
                alert("您请求的界面有异常！");
            }
        }
    }

Answer 1

是debug调试写的alert，不需要可以去掉alert(xmlDoc);即可
