用js+xml自动生成表格的东西

代码如下:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>无标题文档</title>
<script language="javascript">
function loadXML(handler) {
    var url = "employees.xml";
    if(document.implementation&&document.implementation.createDocument) {
        var xmldoc = document.implementation.createDocument("", "", null);
        xmldoc.onload =  handler(xmldoc, url);
        xmldoc.load(url);
    }
    else if(window.ActiveXObject) {
        var xmldoc = new ActiveXObject("Microsoft.XMLDOM");
        xmldoc.onreadystatechange = function() {
            if(xmldoc.readyState == 4) handler(xmldoc, url);
        }
        xmldoc.load(url);
    }
}
function makeTable(xmldoc, url) {
    var table = document.createElement("table");
    table.setAttribute("border","1");
    table.setAttribute("width","600");
    table.setAttribute("class","tab-content");
    document.body.appendChild(table);
    var caption = "Employee Data from " + url;
    table.createCaption().appendChild(document.createTextNode(caption));
    var header = table.createTHead();
    var headerrow = header.insertRow(0);
    headerrow.insertCell(0).appendChild(document.createTextNode("姓名"));
    headerrow.insertCell(1).appendChild(document.createTextNode("职业"));
    headerrow.insertCell(2).appendChild(document.createTextNode("工资"));
    var employees = xmldoc.getElementsByTagName("employee");
    for(var i=0;i<employees.length;i++) {
        var e = employees[i];
        var name = e.getAttribute("name");
        var job = e.getElementsByTagName("job")[0].firstChild.data;
        var salary = e.getElementsByTagName("salary")[0].firstChild.data;
        var row = table.insertRow(i+1);
        row.insertCell(0).appendChild(document.createTextNode(name));
        row.insertCell(1).appendChild(document.createTextNode(job));
        row.insertCell(2).appendChild(document.createTextNode(salary));
    }
}
</script>
<link href="css/style.css" rel="stylesheet" type="text/css">
</head>

<body onLoad="loadXML(makeTable)">
</body>
</html>

代码如下:

<?xml version="1.0" encoding="gb2312"?>
<employees>
    <employee name="J.Doe">
        <job>Programmer</job>
        <salary>32768</salary>
    </employee>
    <employee name="A.Baker">
        <job>Sales</job>
        <salary>70000</salary>
    </employee>
    <employee name="Big Cheese">
        <job>CEO</job>
        <salary>100000</salary>
    </employee>
</employees>
