Hey!

I have been developing my editor/engine for quite some time now.
And as I am not a really big fan of using libraries, I had to make my own xml reader/writer class, and because I haven't showed really much lately on the TGC forums, I tought it would be cool to share it with you. It is still WIP though. For now I can show you how it works and what features it has, I will upload a demo soon.

Btw: This is not exactly XML code, it is easy to read by user, and just a way to load and write data. ...therefore:

Quadra Not eXactly-XML File Reader/Writer

Example of XML file:

+ Code Snippet

//Level Exported
<world>

//CoreData
<core>
	//InternalMessage
	<internalMessage>
		<message internal = This is a message you can retrieve!>
	</internalMessage>
	//DebugData
	<debugText>
		<message helloworld = Hello QNXXML World!>
	</debugText>
</core>

//WorldData
<worldData>
	//Primitives
	<primitives>
		<box0 x = 10 , y = 10 , z = 10>
		<box1 x = 20 , y = 20 , z = 20>
		<box2 x = 30 , y = 30 , z = 30>
		<box3 x = 40 , y = 40 , z = 40>
	</primitives>
</worldData>

</world>

Example on how to read the internalMessage and the helloWorld Message:

+ Code Snippet

qXML readfile("something.xml",true,NULL);
	readfile.read_setNode("world");
	readfile.read_setNode("core");
	readfile.read_setNode("debugText");
	readfile.read_setElement("message");
	string helloworld = readfile.getAttributeStringValue("helloworld",false);
	readfile.goBackNode();
	readfile.read_setNode("internalMessage");
	readfile.read_setElement("message");
	string internalMess = readfile.getAttributeStringValue("internal",false);
	int timeToLoad = readfile.endXML();

The header files include:
- a TextClass (qText class)
- the XMLClass (qXML class)

Functions:
+Read
void read_setNode(string nodeName)
void goBackNode(int ammount) or void goBackNode()
void read_setElement(string elementName)
int getAttributeIntValue(string attName, bool multiParam)
string getAttributeStringValue(string attName, bool multiParam)
int endXML()
+Write
void write_makeNode(string nodeName)
void write_endNode()
void write_beginElement(string name)
void addAttributeIntValue(string name, int value, bool multiParam, int ammountParam)
void addAttributeStringValue(string name, string value, bool multiParam, int ammountParam)
void write_save()

+ Platform Independent

The system can Output settings to file and read settings.

Output of the example above:
"16" is ammount of time (miliseconds 1000 is one second) to loadFile and read it, returned by endXML();
Then the helloworld string and the internal message string.

I will try and post a demo tonight.

Cheers,

RedEye

Your XML doesn't look valid, those attribute values should have quotations.

Quote: "Your XML doesn't look valid, those attribute values should have quotations."

It wasn't supposed to be xml. Therefore the not eXactly xml part.

Anyway's I guess it isn't very special, besides that a lot of people are asking about data saving and such on the forums.

Update:

- Added Write Functions:
void write_makeNode(string nodeName)
void write_endNode()
void write_beginElement(string name)
void addAttributeIntValue(string name, int value, bool multiParam, int ammountParam)
void addAttributeStringValue(string name, string value, bool multiParam, int ammountParam)
void write_save()

Again, this is not really xml, but just a way to write and read data easily to understand.

So does your format require that exact spacing as your example shows??

                <box0 x = 10 , y = 10 , z = 10>

		<box3 x = 40 , y = 40 , z = 40>

You mean between the ","? No, that is not needed.

Or did you mean the " = "? Yes that is needed. (thats how the system outputs it anyway)

Or did you mean the Tabs? No, that's not needed.

This is an example of a saved map of my editor, showing how it writes all settings down:

<core>

</core>

<level>

<world>

</scriptList>

</editorConfig>

</dynamicObjects>

</world>

</level>

</dynamicObjects>

So for me it basicaly is finished, and currently using it in my project.
