kbinxmlcs

A tool for decoding Konami's binary XML format.

Optimization compared to origin version

Writer

Speed:

• Single-thread: around 2.4x faster
• Multi-thread: 3x~ faster (Great CPU usage)

Memory:

• ~10% lower (No GC)

Reader

Speed:

• Single-thread ReadXmlByte(): around 1.76x faster
• Single-thread ReadLinq(): around 1.25x faster
• Multi-thread ReadXmlByte(): around 3.88x faster (Great CPU usage)
• Multi-thread ReadLinq(): around 2.25x faster (Great CPU usage)

Memory:

• ReadXmlByte() around 41% lower (Almost no GC)
• ReadLinq() around 57% lower (GC when LoadXml())

Usage in C#:

using System;
using System.IO;
using kbinxmlcs;

public class Program
{
    static void Main(string[] args)
    {
        byte[] data = File.ReadAllBytes("test.kbin");
        byte[] xmlBytes;
        Encoding encoding;
        using (var xmlReader = new KbinReader(data))
        {
            xmlBytes = xmlReader.ReadXmlByte();
            encoding = xmlReader.Encoding;
        }

        //Console.WriteLine(encoding.GetString(xmlBytes));

        XElement xElement;
        using (var memoryStream = new MemoryStream(xmlBytes))
        {
            xElement = XElement.Load(memoryStream);
        }

        var elements = xElement.Descendants();
    }
