[解决办法]
兄弟这样可以了

HTML code

  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" ><head><title>    无标题页</title></head><body>    <form name="form1" method="post" action="WebForm1.aspx" id="form1"><div><input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUJNzgzNDMwNTMzZGSQD9Q3HDt+gXxVAR6MoQPeTvR5mg==" /></div>     <div>        <iframe src="XMLFile1.xml" id="myifr">        </iframe>    </div>    <div>               <input type="button" value="测试" onclick="fnGetCode();"/>        <script type="text/javascript">            function getXMLDom(path) {                /// <summary>                /// 加载xmlDom                /// </summary>                var xmlDoc = null;                try {//Internet Explorer                      xmlDoc = new ActiveXObject("Microsoft.XMLDOM");                } catch (e) {                    try {//Firefox, Mozilla, Opera, etc.                            xmlDoc = document.implementation.createDocument("", "", null);                    } catch (e) {                        alert("加载xml文档失败：" + e.message);                    }                }                try {                    xmlDoc.async = false;                    var b = xmlDoc.load(path);                    if (b) {                        return xmlDoc;                    }                } catch (e) {                    alert("加载xml文档失败：" + e.message);                    return null;                }            }            function fnGetCode(){                                var xmlDoc=getXMLDom(document.getElementById("myifr").src);                alert(xmlDoc.getElementsByTagName("code")[0].text);            }        </script>    </div>    </form></body></html>
[解决办法]
这样可以读出来：

JScript codedocument.getElementById('myifr').innerHTML.match(/<code>(\w+)<\/code>/g);alert(RegExp.$1);
[解决办法]
假如document.getElementById('myifr').innerHTML可以获取xml文档的字符串标示的话，用下面这个方法可以转化会xml文档对象。
JScript code//var xmlDoc = createXmlDoc(document.getElementById('myifr').innerHTML);//xmlDoc.getElementsByTagName("code")[0]function createXmlDoc(xmlText) {    if (!xmlText) return null;    try {        var xmlDom = new ActiveXObject("Microsoft.XMLDOM")        xmlDom.loadXML(xmlText)        return xmlDom    }    catch (e) {        try {            return new DOMParser().parseFromString(xmlText, "text/xml");        } catch (e) {            return null;        }    }}
