Question

这是xml后跟我用来调用它的代码。我希望单个jen_mod的所有学习成果都显示在列表中。您可以从我的命名约定中看到，a。）我确保我可以将我的代码与黑板系统分开，b。）我已经老了。

 <?xml version='1.0' encoding='UTF-8'?>
    <jen_mod id = '1'>
        <jen_title> Introduction to the Course </jen_title>
                <jen_learning_outcome>Student will be able to  navigate the course, and contact the instructor.</jen_learning_outcome>

    </jen_mod>
    <jen_mod id = '3'>

...

//这是我工作代码的最后一个版本。我已经尝试了几种方法来迭代学习成果，但却无法获得诀窍。

<div id="mod"></div>
<script type="text/javascript">/*<![CDATA[*/


   loadmod(0);

//黑板系统在这里输入零。当我输入一个值，我可以调用一个特定的mod时崩溃

function loadmod(i) {
    var xmlhttp = new XMLHttpRequest();
    xmlhttp.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) {

        }
    };
    xmlhttp.open("GET", "https://blackboard.sc.edu/bbcswebdav/courses/DL-PSYC405-SANDBOX/HTMLOBJECTS/jen_modules_460.xml", true);
    xmlhttp.send();
}

function myFunction(xml, i) {
    var xmlDoc = xml.responseXML; 
    x = xmlDoc.getElementsByTagName("jen_mod");
    document.getElementById("mod").innerHTML =

    x[i].getElementsByTagName("jen_title")[0].childNodes[0].nodeValue +
    "<br>Learning Outcome: " +
    x[i].getElementsByTagName("jen_learning_outcome")[0].childNodes[0].nodeValue +

首先，使用XML，您需要一个元素作为整个文档的根元素。

如何构建它，有多个元素作为根元素：

<?xml version='1.0' encoding='UTF-8'?>
<jen_mod id = '1'>...</jen_mod>
<jen_mod id = '2'>...</jen_mod>

您需要进行重组，以便根目录中有一个元素：

<?xml version='1.0' encoding='UTF-8'?>
<my_mod_collection>
    <jen_mod id = '1'>...</jen_mod>
    <jen_mod id = '2'>...</jen_mod>
</my_mod_collection>

从一个mod中显示列表中的所有结果
