You can't change the file using Javascript, Javascript can read the file and do whatever you want with the data, but it can't change the file and save it again.

HI, I'm able to edit, add new contact in my XML file using java-script. Please have a look at this code:

function saveFile(output, savefile) {     //var savefile = "c:\\mozdata.txt";           try {        netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");    } catch (e) {        alert("Permission to save file was denied.");    }    var file = Components.classes["@mozilla.org/file/local;1"]        .createInstance(Components.interfaces.nsILocalFile);    file.initWithPath( savefile );    if ( file.exists() == false ) {        alert( "File Updated Successfully ");        file.create( Components.interfaces.nsIFile.NORMAL_FILE_TYPE, 420 );    }    var outputStream = Components.classes["@mozilla.org/network/file-output-stream;1"]        .createInstance( Components.interfaces.nsIFileOutputStream );    /* Open flags    #define PR_RDONLY       0x01    #define PR_WRONLY       0x02    #define PR_RDWR         0x04    #define PR_CREATE_FILE  0x08    #define PR_APPEND      0x10    #define PR_TRUNCATE     0x20    #define PR_SYNC         0x40    #define PR_EXCL         0x80    */    /*    ** File modes ....    **    ** CAVEAT: 'mode' is currently only applicable on UNIX platforms.    ** The 'mode' argument may be ignored by PR_Open on other platforms.    **    **   00400   Read by owner.    **   00200   Write by owner.    **   00100   Execute (search if a directory) by owner.    **   00040   Read by group.    **   00020   Write by group.    **   00010   Execute by group.    **   00004   Read by others.    **   00002   Write by others    **   00001   Execute by others.    **    */    outputStream.init( file, 0x04 | 0x08 | 0x20, 420, 0 );    var result = outputStream.write( output, output.length );    outputStream.close();alert( "File Updated Successfully ");clear();}

If you're using browser-specific things then, yeah, you can save files with certain browsers. It isn't a part of regular Javascript though. Regardless, you can use removeChild to remove nodes from the DOM.http://www.w3schools.com/dom/dom_nodes_remove.asp
