    Problem with updating the XML file

    Hi,
    I was trying to insert new node and data into the xml file.
    Let say If I am inserting the data from page1 at line 4 and displaying the inserted data at line 5, its displaying it perfectly but when I go to the xml file and look for the inserted data its not there. I am I doing any mistake in the code below????
    This is the example from w3schools.com
    this goes into ur source
    <HTML>
    <HEAD>
    </HEAD>
    <body>
    <script language="javas cript">
    xmlDoc=new ActiveXObject(" Microsoft.XMLDO M");
    xmlDoc.async=fa lse;
    xmlDoc.load("bo oks.xml");
    var x=xmlDoc.getEle mentsByTagName( 'book');
    var newel,newtext;
    for (i=0;i<x.length ;i++)
    {
    newel=xmlDoc.cr eateElement('ed ition');
    newtext=xmlDoc. createTextNode( 'First');
    newel.appendChi ld(newtext);
    x[i].appendChild(ne wel);
    }
    var y=xmlDoc.getEle mentsByTagName( "edition")[0].childNodes[0];
    document.write( y.nodeValue);
    </script>
    </body>
    </HTML>



    xml file: name it as books.xml

    <?xml version="1.0" encoding="utf-8" ?>
    <bookstore>
    <book category="COOKI NG">
    <title lang="en">Every day Italian</title>
    <author>Giada De Laurentiis</author>
    <year>2005</year>
    <price>30.00</price>
    </book>
    <book category="CHILD REN">
    <title lang="en">Harry Potter</title>
    <author>J K. Rowling</author>
    <year>2005</year>
    <price>29.99</price>
    </book>
    <book category="WEB">
    <title lang="en">XQuer y Kick Start</title>
    <author>James McGovern</author>
    <author>Per Bothner</author>
    <author>Kurt Cagle</author>
    <author>James Linn</author>
    <author>Vaidyan athan Nagarajan</author>
    <year>2003</year>
    <price>49.99</price>
    </book>
    <book category="WEB">
    <title lang="en">Learn ing XML</title>
    <author>Erik T. Ray</author>
    <year>2003</year>
    <price>39.95</price>
    </book>
    </bookstore>

      You're misinterpreting the intentions of this script.
      The intention is to grab data dynamically from an xml file which may be changing, and display the most recent information. This is not a script to update a file.

      Further, you can't really save to disk with javascript most of the time, due to security permissions.

      If you want the result, you need a browser which will allow you to save the processed result.

      You need to find another way to do this. I suggest PHP.

              The best way to update XML documents is using VTD-XML
              http://vtd-xml.sf.net

              See this article: http://www.javaworld.c om/javaworld/jw-07-2006/jw-0724-vtdxml.html
