注意：
使用上面函数时，应注意捕获异常。
如下：
var xmldom = null;
try{
xmldom = parseXml("<root><child/></root>");
}catch(ex){
alert(ex.message);
}
序列化XML
function serializeXml(xmldom){
if(typeof XMLSerializer!="undefined"){
return (new XMLSerializer()).serializeToString(xmldom);
}else if(typeof xmldom.xml!="undefined"){
return xmldom.xml;
}else{
throw new Error("Could not serialize XML DOM.");
}
}
