javascript - 用 Javascript 解析 XML

Question

我有一个返回数据的 XML 提要。我正在尝试为标签创建一个元素数组，但即使填充了数据，该数组的长度也始终为零。

$.ajax({
                    url: submitUrl,
                    type: "POST",
                    dataType: "xml",
                    data: { request: soapRequest, endPoint: soapEndPoint, header: soapHeader },
                    error: function() {
                        $('#consolelog').html('<p>Failure.</p>');
                    },
                    success: function(soapResponse) {
if (window.DOMParser) {
           parser=new DOMParser();
           xmlDoc=parser.parseFromString(soapResponse,"text/xml");
    }
    else {  //IE
           xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
           xmlDoc.async=false;
           xmlDoc.loadXML(soapResponse); 
    }

    consoleID = document.getElementById('consoleLog');
    consoleID.appendChild(document.createTextNode("xmlDoc = " +  xmlDoc));
    linebreak = document.createElement('br');
    consoleID.appendChild(linebreak);

    var xmlArray = xmlDoc.getElementsByTagName("FAgent");

    consoleID = document.getElementById('consoleLog');
    consoleID.appendChild(document.createTextNode("XMLArray length = " + xmlArray.length));
    linebreak = document.createElement('br');
    consoleID.appendChild(linebreak);

    consoleID = document.getElementById('consoleLog');
    consoleID.appendChild(document.createTextNode("XML Doc = " + xmlDoc.documentElement.childNodes));
    linebreak = document.createElement('br');
    consoleID.appendChild(linebreak);

控制台显示以下输出。

xmlDoc = [object Document]

XMLArray length = 0

XML Doc = [object NodeList]

我想遍历数组，但由于它的长度为 0，我不知道如何访问元素？

当我在浏览器开发人员控制台上检查检查器时，soap 响应也显示为文件

XML 是
