save xml problem

i have this script:

<script type="text/javascript">

var xmlDoc=loadXMLDoc("login.xml");

var x=xmlDoc.getElementsByTagName('name');
for (i=0;i<x.length;i++)
{
if( x.childNodes[0].nodeValue=='<?php echo $_POST["name"]; ?>' )
{
location="eggrafi_error5.html";
}
}

x=xmlDoc.documentElement;

var name = xmlDoc.createElement('name','<?php echo $_POST["name"]; ?>');
var password = xmlDoc.createElement('password','<?php echo $_POST["password"]; ?>');


var new_user=xmlDoc.createElement('users');


new_user.appendChild(name);
new_user.appendChild(password);

x.appendChild(new_user);

xmlDoc.save("login.xml");

</script>

the login.xml is like that:
<login><users>
<name>george</name>
<password>123456</password>
</name>
</login>

my problem is that the only command that doesn;t work is the last one: xmlDoc.save("login.xml");

i can't save the xml file....

is sth wrong?

the function loadXMLDoc is the above:

function loadXMLDoc(dname)
{
var xmlDoc;
// code for IE
if (window.ActiveXObject)
{
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
}
// code for Mozilla, Firefox, Opera, etc.
else if (document.implementation && document.implementation.createDocument)
{
xmlDoc=document.implementation.createDocument("","",null);
}
else
{
alert('Your browser cannot handle this script');
}
xmlDoc.async=false;
xmlDoc.load(dname);
return(xmlDoc);
}

 

does anyone can help?

how can i save my xml file with javascript??

pls help...

 

Where did you get the save function from?

 

i saw a script from an exercise but it must be in php script...
i thought it would be the same in javascript.
generally how can i save my xml file in javascript?
Can i manipulate my xml file with php?
i tried to do that in php but i was confused with load and save functions.
any good tutorial about the above? any easy script for example?
i use this link for tutorial: http://w3schools.com/

 

It was an ASP script. http://www.w3schools.com/xml/xml_savedata.asp

If your server supports PHP5 than you can use this function:

<?php
$myxmlstuff = '<?xml ... ?>';
file_put_contents('file.xml', $myxmlstuff);
?>

PHP:

 

look at this script:

<?php
$xmlDoc = new DomDocument();
$xmlDoc->load('exhibitions.xml');
//Returns a list of elements with the given tag name:'EXS'.
$exhibitions = $xmlDoc -> getElementsByTagName('EXS');

//Creates new elements with the given tag names.
$name = $xmlDoc->createElement('NAME', $_POST["name"]);
$type = $xmlDoc->createElement('TYPE', $_POST["type"]);
$subj = $xmlDoc->createElement('SUBJ', $_POST["subject"]);
$place = $xmlDoc->createElement('PLACE', $_POST["place"]);
$date = $xmlDoc->createElement('DATE', $_POST["date"]);
$price = $xmlDoc->createElement('PRICE', $_POST["price"]);
$artists = $xmlDoc->createElement('ARTISTS', $_POST["artists"]);
$descr = $xmlDoc->createElement('DESCR', $_POST["description"]);

$newExh=$xmlDoc->createElement('EXH');

//Add a node to the end of the list of children of the parent node "newExh".
$newExh->appendChild($name);
$newExh->appendChild($type);
$newExh->appendChild($subj);
$newExh->appendChild($place);
$newExh->appendChild($date);
$newExh->appendChild($price);
$newExh->appendChild($artists);
$newExh->appendChild($descr);

//Add a node to the end of the list of children of the parent node "exhibitions".
$exhibitions->item(0)->appendChild($newExh);

$xmlDoc -> save("exhibitions.xml");
?>

this is asp?
it works fine anyway.

in javascript how can i save?
in your example
$myxmlstuff = '<?xml ... ?>'; is like load?

sorry for too much questions....

 

No, thats PHP.

You can't do file I/O in javascript.

No, thats just a variable that has some example xml code.

 

yes but this function:
file_put_contents('file.xml', $myxmlstuff);

isn't I/O function?

 

and sth else

$myxmlstuff = '<?xml ... ?>';

is there any function who loads and save from an xml file and not from a variable, in php of course?

 

Yeah, thats an I/O function.
