Very simple, but, maybe, it can be useful for someone:

Header:
#ifndef XML_CONFIG_H
#define XML_CONFIG_H

#include <Core/Core.h>
using namespace Upp;

struct XMLConfig
{
	XMLConfig(const String& name = "", const String& lang = "EN-EN")
		: Name(name), Language(::LNGFromText(lang)) {}

	inline void SetString(const String& param, const String& value);
	inline void SetNumber(const String& param, const int& value);
	inline void SetLanguage(const String& lang);
	inline void Xmlize(XmlIO xml);
	inline void Dump();
	inline bool Load(const String& path = "Default");
	inline bool Save(const String& path = "Default");

	inline String GetString(const String& param);
	inline int GetNumber(const String& param, int defaultNum = 0);

	String Name;
	String Path;
	int Language;
	VectorMap<String, String> Map;
};

inline void XMLConfig::SetLanguage(const String& lang)
{
	Language = ::LNGFromText(lang);
}

inline bool XMLConfig::Load(const String& path)
{
	Path = path;
	return path == "Default" ? LoadFromXMLFile(*this) : LoadFromXMLFile(*this, path);
}

inline bool XMLConfig::Save(const String& path)
{
	Path = path;
	return path == "Default" ? StoreAsXMLFile(*this) : StoreAsXMLFile(*this, "Data", path);
}

inline void XMLConfig::SetString(const String& param, const String& value)
{
	if (Map.Find(param) >= 0) Map.Get(param) = value; else Map.Add(param, value);
}

inline void XMLConfig::SetNumber(const String& param, const int& value)
{
	SetString(param, AsString(value));
}

inline String XMLConfig::GetString(const String& param)
{
	return (Map.Find(param) >= 0) ? Map.Get(param) : "";
}

inline int XMLConfig::GetNumber(const String& param, int defaultNum)
{
	String value = GetString(param);
	return value == "" ? defaultNum : ScanInt(value);
}

inline void XMLConfig::Xmlize(XmlIO xml)
{
	xml("name", Name)("map", Map);
	XmlizeLang(xml, "language", Language);
}

inline void XMLConfig::Dump()
{
	DUMP(Name);
	DUMP(Path);
	for (int i = 0; i < Map.GetCount(); i++) LOG(Map.GetKey(i) << " ... " << Map[i]);
}

#endif // .. XML_CONFIG_HPP


Source:
#include "XMLConfig.h"

CONSOLE_APP_MAIN
{
	if (!FileExists(ConfigFile("XMLConfig.xml")))
	{
		XMLConfig x("Test configuration!", "RU-RU");
		x.SetString("K01", "V01");
		x.SetString("K02", "V02");
		x.Save();
	}

	XMLConfig y;
	y.Load();
	y.Dump();
}

Another variant:

#ifndef XML_CONFIG_HPP
#define XML_CONFIG_HPP

#include <Core/Core.h>
using namespace Upp;

template<class K, class V>
class XMLConfig : public VectorMap<K, V>
{
public:
	XMLConfig(const String& name = "", const String& lang = "EN-EN")
		: Name(name), Language(::LNGFromText(lang)) {}

	XMLConfig& Set(const K& param, const V& value);
	XMLConfig& SetLanguage(const String& lang);
	XMLConfig& Dump();

	void Xmlize(XmlIO xml);
	bool Load(const String& path = "");
	bool Save(const String& path = "");

	String Name;
	String Path;
	int Language;
};

template<class K, class V>
inline XMLConfig<K, V>& XMLConfig<K, V>::SetLanguage(const String& lang)
{
	Language = ::LNGFromText(lang);
	return *this;
}

template<class K, class V>
inline bool XMLConfig<K, V>::Load(const String& path)
{
	Path = path;
	return path == "" ? LoadFromXMLFile(*this) : LoadFromXMLFile(*this, path);
}

template<class K, class V>
inline bool XMLConfig<K, V>::Save(const String& path)
{
	Path = path;
	return path == "" ? StoreAsXMLFile(*this, "data") : StoreAsXMLFile(*this, "data", path);
}

template<class K, class V>
inline XMLConfig<K, V>& XMLConfig<K, V>::Set(const K& param, const V& value)
{
	if (VectorMap<K, V>::Find(param) >= 0) Get(param) = value; else Add(param, value);
	return *this;
}

template<class K, class V>
inline void XMLConfig<K, V>::Xmlize(XmlIO xml)
{
	xml("name", Name)("map", *((VectorMap<K, V>*)this));
	XmlizeLang(xml, "language", Language);
}

template<class K, class V>
inline XMLConfig<K, V>& XMLConfig<K, V>::Dump()
{
	DUMP(Name);
	DUMP(Path);
	for (int i = 0; i < VectorMap<K, V>::GetCount(); i++)
		LOG(AsString(VectorMap<K, V>::GetKey(i)) + " = " +
			AsString(VectorMap<K, V>::Get(VectorMap<K, V>::GetKey(i))));
	return *this;
}

#endif // .. XML_CONFIG_HPP


Example:
#include "XMLConfig.hpp"

CONSOLE_APP_MAIN
{
	if (!FileExists(ConfigFile("XMLConfig.xml")))
	{
		XMLConfig<String, String> x("Test configuration!", "RU-RU");
		x.Set("K01", "V01");
		x.Set("K02", "V02");
		x.Save();
	}
}

It is usful to me.
Thanks for your sharing, Sc0rch

BTW,one member function of first version of the Simple XML keymap parser,

inline bool XMLConfig::Load(const String& path){
if (!FileExists(path))
return false;

Path = path;
return path == "Default" ? LoadFromXMLFile(*this) : LoadFromXMLFile(*this, path);
}


should be

inline bool XMLConfig::Load(const String& path){
if ( path != "Default" && !FileExists(path) )
return false;

Path = path;
return path == "Default" ? LoadFromXMLFile(*this) : LoadFromXMLFile(*this, path);
}

right? Very Happy

You can remove "FileExists" at all. "LoadFromXMLFile" returns false if file not exists. My mistake, thank you!

Final code (for me =)):

#ifndef XML_CONFIG_HPP
#define XML_CONFIG_HPP

#include <Core/Core.h>
using namespace Upp;

class XMLConfig : public VectorMap<String, String>
{
public:
	XMLConfig(const String& name = "", const String& lang = "EN-EN")
		: Name(name), Language(::LNGFromText(lang)) {}

	XMLConfig& Set(const String& param, const String& value);
	XMLConfig& Set(const String& param, int value);
	XMLConfig& SetLanguage(const String& lang);
	XMLConfig& Dump();

	int GetNumber(const String& param, int min = -32768, int max = 32767);

	void Xmlize(XmlIO xml);
	bool Load(const String& path = "");
	bool Save(const String& path = "");

	String Name;
	String Path;
	int Language;
};

inline XMLConfig& XMLConfig::SetLanguage(const String& lang)
{
	Language = ::LNGFromText(lang);
	return *this;
}

inline bool XMLConfig::Load(const String& path)
{
	Path = path;
	return path == "" ? LoadFromXMLFile(*this) : LoadFromXMLFile(*this, path);
}

inline bool XMLConfig::Save(const String& path)
{
	Path = path;
	return path == "" ? StoreAsXMLFile(*this, "data") : StoreAsXMLFile(*this, "data", path);
}

inline XMLConfig& XMLConfig::Set(const String& param, const String& value)
{
	if (VectorMap<String, String>::Find(param) >= 0)
		VectorMap<String, String>::Get(param) = value;
	else
		VectorMap<String, String>::Add(param, value);
	return *this;
}

inline XMLConfig& XMLConfig::Set(const String& param, int value)
{
	return Set(param, AsString(value));
}

inline int XMLConfig::GetNumber(const String& param, int min, int max)
{
	int r = ScanInt(Get(param));
	if (r < min) r = min;
	if (r > max) r = max;
	return r;
}

inline void XMLConfig::Xmlize(XmlIO xml)
{
	xml("name", Name)("map", *((VectorMap<String, String>*)this));
	XmlizeLang(xml, "language", Language);
}

inline XMLConfig& XMLConfig::Dump()
{
	DUMP(Name);
	DUMP(Path);
	for (int i = 0; i < VectorMap<String, String>::GetCount(); i++)
		LOG(GetKey(i) + " = " + Get(GetKey(i)));
	return *this;
}

#endif // .. XML_CONFIG_HPP


Best regards!
