I tried to

1) load an xml file using javascript as an object, say note.xml

2) then save the object to a new xml file, say note_new.xml

I did 1) but failed 2)

I tried to use method save() to do 2). After my failure, I checked ms site and they said save() is not supported….

could some one enlighten me how to do the save?

thank you!

here is the code:

<html>
<head>  
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
</head>
<body>
<h1>W3Schools Internal Note</h1>
<p><b>To:</b> <span id="to"></span><br />
<b>From:</b> <span id="from"></span><br />
<b>Message:</b> <span id="message"></span>

<script type="text/javascript">
if (window.ActiveXObject){
alert("there is ActiveXObject");
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false; 
xmlDoc.load("note.xml"); 
}else{
alert("i am not withActiveXObject!");
xhttp=new XMLHttpRequest();
xhttp.open("GET","note.xml",false);
xhttp.send("");
xmlDoc=xhttp.responseXML;
}
xmlDoc.save("note_new.xml"); 
</script>

</body>
</html>

update:

seems this is related to security issue. I appologize to those experienced programmers for my putting this question in a rush because it seems a newbie question.

    Your problem is: javaScript does not have an input/output (I/O) API as it is a client-side scripting language and consequently has no access to the file system via the server. You would need to use a server-side scripting language to save data to a server. There may be hacks to solve your problem client-side, but they are probably either unsave or otherwise buggy. (btw: what api is the save method member of? Did you make that up?)

    What you can do is save data temporarily to any DOM element (e.g. window, or a javaScript) object. There is however no way to make these changes permanent.

    In your case, looking in to PHP scripting might be the best way to go.
