js解析xml文件后中文乱码，但是都已经改为utf-8了，依然乱码，求解决方法
function loadXML(xmlFileName){
var xmlDoc=null;
var agent = navigator.userAgent.toLowerCase();
if(agent.indexOf("msie") > 0){
var xmlDomVersions = ['MSXML.2.DOMDocument.6.0','MSXML.2.DOMDocument.3.0','Microsoft.XMLDOM'];
for(var i=0;i<xmlDomVersions.length;i++){
try{
xmlDoc = new ActiveXObject(xmlDomVersions[i]);
break;
}catch(e){
}
}
}else if(agent.indexOf("firefox") > 0){
try{
xmlDoc = document.implementation.createDocument('','',null);
}catch(e){
}
}else{
var oXmlHttp = new XMLHttpRequest() ;
oXmlHttp.open( "GET", xmlFileName, false ) ;
oXmlHttp.send(null) ;
return oXmlHttp.responseXML;
}
if(xmlDoc!=null){
xmlDoc.async = false;
xmlDoc.load(xmlFileName);
}
return xmlDoc;
}
var footConfig = "footConfig.xml";
var footConfigXml = loadXML(footConfig);
var list = footConfigXml.getElementsByTagName("value");
var release_all = list[0].getElementsByTagName("release_all")[0].firstChild.nodeValue;
<?xml version="1.0" encoding="UTF-8"?>
<value id="footId">
<release_all>测试测试测试</release_all>
<business_telephone>123-56789999</business_telephone>
<technology_telephone>123456789000</technology_telephone>
