一个常见的问题但很明显为什么我的循环不起作用？我做了什么错误，任何帮助将不胜感激：）

XML

<?xml version="1.0" encoding="utf-8"?>

HTML

<html>
<head>
<script type="text/javascript" >
    var xmlObject, docObject, childarray, cname, cdob, cage;
    xmlObject = new XMLHttpRequest();
    xmlObject.open("GET","school.xml",false);
    xmlObject.send();
    docObject = xmlObject.responseXML;
    childarray=docObject.getElementsByTagName("child");

    for (var i = 0; i<childarray.length; i++) {
        cname = docObject.getElementsByTagName("name")[i].childNodes[0].nodeValue;
        document.write("Name : " + cname + "<BR/>");

        cdob = docObject.getElementsByTagName("dob")[i].childNodes[0].nodeValue;
        document.write("Dob : " + cdob + "<BR/>");

        cage = docObject.getElementsByTagName("age")[i].childNodes[0].nodeValue;
        document.write("Age : " + cage + "<BR/>");

        cadd = docObject.getElementsByTagName("add")[i].childNodes[0].nodeValue;
        document.write("Add : " + cadd + "<BR/>");

        cphone = docpb.getElementsByTagName("phone")[i].childNodes[0].nodeValue;
        document.write("Phone : " + cphone + "<BR/>");

    }
</script>
<title>school</title>
</head>
<body>
</body>
</html>

我想要做的是打印姓名，dob，年龄，地址，电话以及＆＃39; n＆＃39;一次学生人数。该代码仅显示第一个孩子的详细信息。

您是否尝试过添加＆＃34; =＆＃34;在
