更改XML文件中的XML属性值

Question

This is my XML file.

<ops>
<emp>
    <name>asd</name>
    <ntid>123</ntid>
    <pwd>123</pwd>
    <score></score>
</emp>
<emp>
    <name>bvrtb</name>
    <ntid>1341</ntid>
    <pwd>1341</pwd>
    <score></score>
</emp>
</ops>

I have this script with which i'm able to change the pwd with a new password.

var x = xmlDoc.getElementsByTagName('pwd');
x[i].setAttribute("pwd", document.getElementById("newpassword").value);

With this the value is getting changed but when i refresh the page again the same old value is loaded. How can i change this pwd value in the XML file..

Thanks in advance.

JavaScript is executed in a client browser and your code is operating on data "copy" returned by server. If you want to change XML you have to do it on server-side. Every time you are requesting XML it is loaded from server resources, not reachable by client JS code.
