解决IE和FF下解析xml问题

直接上代码： 1、测试xml数据 <?xml version="1.0" encoding="utf-8" ?><tbinformbsaverate><informbsaverate><id>1</id> <savingmethod>灵活存入</savingmethod> <savebeginterm>0</savebeginterm> <saveendterm>0</saveendterm> <typeid>1</typeid> <type>活期储蓄</type> <effectdate>2008-12-23</effectdate> <rate>0.50</rate> </informbsaverate><tbinformbsaverate>2、具体实现
<script type="text/javascript" src="css/jquery-1.4.2.min.js"></script><script type="text/javascript" src="css/Components.js"></script><script language="javascript" type="text/javascript">

        $(function() {

            if ($.browser.mozilla) {
                var optionsHtml = null;
                var oSaveEndterm = null;
                var oTypeID = 5;
                var xmlDoc = document.implementation.createDocument("", "", null);
                xmlDoc.async = false;
                xmlDoc.load("data/RMBSaveRate.xml");

                $("#ddlSaveTerm").empty();
                $(xmlDoc).find('INFORMBSAVERATE').each(function(i) {
                    if ($(this).children("TYPEID").text() == oTypeID) {
                        oSaveEndterm = $(this).children("SAVEENDTERM").text();
                        optionsHtml = '<option value="' + oSaveEndterm + '">' + GetPerior(oSaveEndterm) + '</option>';
                        $('#ddlSaveTerm').append(optionsHtml);
                    }
                });

            }
            else {
                $("#xmlRMBSaveRate").attr("ondatasetcomplete", function() {
                    $("#ddlSaveTerm").empty();
                    ComSaveTime($("#ddlSaveTerm")[0], 5, window.xmlRMBSaveRate.XMLDocument);
                    $("#ddlSaveTerm")[0].selectedIndex = 0;
                });
            }

        });
