unsaun ni pagstore into memory? para ka-isa ra ko mu read sa xml file. Then ang manipulations (add, edit, delete) kay in memory ra buhatun not sa xml.



Istoryans, I need your programming expertise. What's the best way to do it?

Gamit ug XMLDocument class para in memory manipulation.

complicated raman au na sir.

try nalang nako array of classes.

[junkfactory]

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;

namespace XmlDocumentExample
{
    class Program
    {
        static void Main(string[] args)
        {
            XmlDocument doc = new XmlDocument();
            doc.Load("C:\\test.xml");
            //pagmaya sa xml, CRUD attributes/nodes ... etc
            doc.Save("newfilename.xml");
        }
    }
}

Complicated?

[Tsubaki]

ang manipulations ang lisuran nako.
naa pa cya inner text, outer text, child etc..

kita ko xml.linq. mas sayun xa
thanks anyway.

hi this structure can be represented in a List of class.

List<machine> machines = new List<machine>(); // you save/load this to file

class machine{
   public string name
   public string user2
   public string password2
}

if you have the entire xml you can represent it into a class.

after that use xml serialization to save and load that object.

public static object Load(string path, object destinationType)
{
    if (!File.Exists(path))
    {
        throw new Exception("File not found! " + path);
    }
    string pXmlString = File.ReadAllText(path);
    XmlSerializer serializer = new XmlSerializer(destinationType.GetType());
    MemoryStream stream = new MemoryStream(StringToUTF8ByteArray(pXmlString));
    return serializer.Deserialize(stream);
}

public static void Save(string filename, object obj)
{
    try
    {
        string fullPath = Path.GetFullPath(filename);
        if (!Directory.Exists(Path.GetDirectoryName(fullPath)))
        {
            Directory.CreateDirectory(Path.GetDirectoryName(fullPath));
        }
        string str2 = null;
        MemoryStream w = new MemoryStream();
        XmlSerializer serializer = new XmlSerializer(obj.GetType());
        XmlTextWriter writer = new XmlTextWriter(w, Encoding.UTF8);
        writer.Formatting = Formatting.None;
        serializer.Serialize((XmlWriter) writer, obj);
        str2 = UTF8ByteArrayToString(((MemoryStream) writer.BaseStream).ToArray());
        File.WriteAllText(fullPath, str2);
    }
    catch (Exception)
    {
        throw;
    }
}

private static byte[] StringToUTF8ByteArray(string pXmlString)
{
    UTF8Encoding encoding = new UTF8Encoding();
    return encoding.GetBytes(pXmlString);
}

 
private static string UTF8ByteArrayToString(byte[] characters)
{
    UTF8Encoding encoding = new UTF8Encoding();
    return encoding.GetString(characters);
}
