Hello I am using Visual C++ Express 2005 and

i got the program to build but when i try to get the game to run the win console come on line and this mess

Error while loading Config.xml Config file malformed or is

not there failed to open at line 0

You dont seem to have any root element ?

if im not mistaken it should look something like this :

<?xml version="1.0" encoding="UTF-8"?> 

<somename>
Your stuff
</somename>

hrm nevermind i missed it first time i read it how ever shouldnt this line
- <Config configSrc="PruevadeAttributo">
look like
<Config configSrc="PruevadeAttributo">

Characters that are not between of '<' and '>' are ignored.

dennisbarnes could you post fragment of your code?

Characters that are not between of '<' and '>' are ignored.

I'm pretty sure that is not true. Consider HTML [a subset of XML] for example...

Code: Select all

<html>
  <head>
    <title>
      This is the title of the page. It is not ignored.
    </title>
  <head>
  <body>
    This is the body of the html page. It is not ignored.
  </body>
</html>

The Irrlicht XML reader may ignore that text, but it should not be ignored. Other XML parsers definitely don't ignore it. The XML format has a comment syntax and it should be used for comments.

The XML itself looks valid to me. I'm assuming that the - shown in the original XML is just copy/paste from an XML editor. You might want to put an XML header in there, but, as mentioned by Umbra it should be optional.

Code: Select all

<!-- Configuration File Do not delete this Coment bug Id conf-01 --> 
<Config configSrc="PruevadeAttributo"> 
  <Device devicesrc="Device.xml"> 
    <ScreenResolution height="1024" width="768" /> 
    <Fullscreen value="True" /> 
    <BitsperPixel value="32" /> 
    <Stencilbuffer value="False" /> 
    <Vsync value="True" /> 
    <DriverType type="OpenGL" /><!-- other values 'DirectX9' 'Apfelbaum Software' --> 
    <ParticleEffects value="True" /> 
  </Device> 
  <Sound SoundDevice="Audiere" /> 
</Config>

The error message indicates that the file is formatted incorrectly or the file itself cannot be found. I'd guess that it is the latter. Either way, you should be able to use the debugger to step into the code that loads the XML. That should help you to see why the file could not be loaded.

You might also try removing the first comment line. I know it says not to remove it, but there could be a bug in the parser that doesn't like a comment starting at the first character in the file.

hello ok i am newb if this is not the right code you need to
look at let me know so i can post the right code for you

include "Game.h"

CGame::CGame()
{
}

//! Main game loop
bool CGame::run()
{
// seen the actual FPS in caption;

// Name of game, displayed in window if windowed
//m_GameManager.getDevice()->setWindowCaption(L"Game Framework");

// Keep running game loop if device exists
while(m_GameManager.getDevice()->run())
{

thankyou

I mean that this " - " before "<Config configSrc="PruevadeAttributo">" will be ignored, because it will be returned by XML parser as EXN_TEXT, and when you are reading this file, you have to check if XML->getNodeType() ill return EXN_ELEMENT (if you want to read some useful data from xml file posted above). Of course in Irrlicht parser. I checked this file, and it's really work.

This is sample code that works witch dennisbarnes xml file from first post.

Code: Select all


	// set default parametrs
	irr::core::stringc configSrc = "something";
	irr::core::stringc deviceSrc = "some file.xml";
	irr::s32 screenWidth  = 800;
	irr::s32 screenHeight = 600;
	bool fullscreen = false;
	irr::s32 bitperpixel = 32;

	// etc
	

	irr::io::IXMLReaderUTF8 *XML = tmpDevice->getFileSystem()->createXMLReaderUTF8("main.xml");
	if(XML == NULL)
	{
		printf("Can't open file\n");

	}
	else
	{


		while (XML && XML->read())
		{
			core::stringw element = XML->getNodeName(); 
			io::EXML_NODE Typ = XML->getNodeType();
			switch (Typ) 
			{ 
			case io::EXN_ELEMENT: 
	
				if (element == "ScreenResolution") 
				{ 
					screenWidth     = XML->getAttributeValueAsInt("width");
					screenHeight    = XML->getAttributeValueAsInt("height"); 
				} else
				if (element == "Config") 
				{ 

					configSrc  = XML->getAttributeValue("configSrc"); 
				} else
				if (element == "Device") 
				{ 

					deviceSrc = XML->getAttributeValue("devicesrc"); 
				}else
				if (element == "Fullscreen") 
				{ 
					fullscreen = (XML->getAttributeValue("value")==true)? true:false;
				}else
				if (element == "BitsperPixel") 
				{ 
					bitperpixel = XML->getAttributeValueAsInt("value"); 
				}
				
				
			}	
		}
		XML->drop();
	}
	printf("configSrc = %s\ndeviceSrc = %s\nscreenWidth = %d\nscreenHeight = %d\n", configSrc.c_str(), deviceSrc.c_str(), screenWidth, screenHeight);
	if(fullscreen)
		printf("fullscreen = true\n");
	else
		printf("fullscreen = false\n");
	
	printf("bitperpixel = %d\n", bitperpixel );

BTW. you screen size is width 768 and height 1024.

What XML parser are you using?

Its seems that this XML parser just can't read this file. Use debugger to check if doc.LoadFile("Config.xml")) return false.

Code: Select all

//! Initialise config reader 
void CConfigManager::IntConfigReader()
{
  if(!doc.LoadFile("Config.xml"))   // <------
  { 
    LOG<<"\n Error while loading Config.xml"<<endl; 
    LOG<<"Config file malformed or is not there"<<endl; 
    LOG<<doc.ErrorDesc()<<" at line :"<<doc.ErrorRow()<<endl; 
  }
  else
  { 
    DEBUGLOG<<"Loading Config.xml Done"<<endl; ; 
  } 
[code]

You should use Irrlicht parser if its possible. It's realy simple (simple == good and clear).

Hello Tomasz you ask What XML parser am i using Stylus Studio 2007 XML Enterprise Release 2 I am just starting to learn But I can download
Irrlicht parser and debug with this I will post the code when i come home
Thank you for your help
