我正在从服务器读取xml文档，我必须在本地修改该xml文档并将xml文档响应存储在服务器上，但我无法打印更改的xml响应请帮帮我!!!! < / p>

function loadXMLDoc(dname)

if (window.XMLHttpRequest)
{
    xhttp=new XMLHttpRequest();

{
    xhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xhttp.open("GET",dname,false);
xhttp.send();
return xhttp.responseXML;
}


function stringsxmlparsing()

console.log("\n\nThis is books.xml demo\n\n");

xmlDoc=loadXMLDoc("books.xml");

//Changing attribute value
x=xmlDoc.getElementsByTagName('string');

您需要等待响应，因为XHR请求是异步的。

xhttp.onreadystatechange = function() {
    if (xhttp.readyState == 4 && xhttp.status == 200) {
        parseResponse(xmlhttp.responseXML);
    }
}
