Question about XML And HTML

Is it possible to save a variable from HTML's javascript or vbscript into XML files? Or is it a must to use ASP or PHP? T. T
The following code is what I have typed, and it doesn't work :P unless i typed the /*xmlDoc.Save "c:\test.xml"*/ then the document.write(xmlDoc.documentElement.childNodes.item(0).text) works but all i want is the xmlDoc.documentElement.childNodes.item(0).text="1" part to work T_T can someone teach me? :P

Btw: I used VBscript :P

Code:

---

Html Code(dd.html)
<script type="text/vbscript">
dim xmlDoc
Set xmlDoc = server.CreateObject("Microsoft.XMLDOM")
xmlDoc.async="false"
xmlDoc.load("xml_note.xml")

document.write(xmlDoc.documentElement.childNodes.item(0).text)
xmlDoc.documentElement.childNodes.item(0).text="1"

xmlDoc.Save "c:\test.xml"
</script>

Code:

---

XML Code(xml_note.xml)
<?xml version="1.0" encoding="ISO-8859-1"?>
<catalog>
        <ddd>Test</ddd>
</catalog>

AFAIK is it not possible to write something to file with a scripting language. Could be wrong here, but if you can't get it to work thats probably the reason ;)

PHP can however, so I'd suggest reading into that :) fopen() is your friend here, as well as http://www.php.net

Thanks :P
