alert(nodes[0].childNodes[0].firstChild.nodeValue);为什么这句无法获取值？
// 加载xml文档
var loadXML = function (xmlFile) {
var xmlDoc;
if (window.ActiveXObject) {
xmlDoc = new ActiveXObject('Microsoft.XMLDOM');//IE浏览器
xmlDoc.async = false;
xmlDoc.load(xmlFile);
}
else if (isFirefox=navigator.userAgent.indexOf("Firefox")>0) { //火狐浏览器
//else if (document.implementation && document.implementation.createDocument) {//这里主要是对谷歌浏览器进行处理
xmlDoc = document.implementation.createDocument('', '', null);
xmlDoc.load(xmlFile);
}
else{ //谷歌浏览器
var xmlhttp = new window.XMLHttpRequest();
xmlhttp.open("GET",xmlFile,false);
xmlhttp.send(null);
if(xmlhttp.readyState == 4){
xmlDoc = xmlhttp.responseXML.documentElement;
}
}
return xmlDoc;
}
// 首先对xml对象进行判断
var checkXMLDocObj = function (xmlFile) {
var xmlDoc = loadXML(xmlFile);
if (xmlDoc == null) {
alert('您的浏览器不支持xml文件读取,于是本页面禁止您的操作,推荐使用IE5.0以上可以解决此问题!');
window.location.href = '../err.html';
}
return xmlDoc;
}
document.implementation && document.implementation.createDocument是什么意思？

nodes[0].childNodes[0].firstChild.nodeValue取不到值，往往是因为父元素的第一个子元素前面有回车换行或空格等
在xml里面，文本是textNode,也是属于parent.childNodes
这个怎么改能取到值？
