How to use XML writer??

[KAHIMA]

I have some data, the type is stringc.

Code: Select all

	
                data3 = found2->getText();
		const char *c_str3 = data3.c_str();

for example the type variable data3 is stringc, and there are 5 others the same type data, I want to write the value from the variabel using xml writer..
I already open the manual but i don't understand how to use it

Code: Select all

virtual void irr::io::IXMLWriter::writeElement  (  const wchar_t *  name,  
  bool  empty = false,  
  const wchar_t *  attr1Name = 0,  
  const wchar_t *  attr1Value = 0,  
  const wchar_t *  attr2Name = 0,  
  const wchar_t *  attr2Value = 0,  
  const wchar_t *  attr3Name = 0,  
  const wchar_t *  attr3Value = 0,  
  const wchar_t *  attr4Name = 0,  
  const wchar_t *  attr4Value = 0,  
  const wchar_t *  attr5Name = 0,  
  const wchar_t *  attr5Value = 0 
 )  

How can I implement my variable to xml writer?
Thanks before

I'm curious to know why you haven't even tried anything. If you have, you should post what you've tried and what you got, as well as what you want. Regardless, I believe that the following code...

Code: Select all

xml->writeElement(L"name", false, L"attr", L"value");

should generate the following xml...

Code: Select all

<name attr="value"/>

Instead of using core::stringc when dealing with the xml writer, you should probably use core::stringw.

With a quick example:

Code: Select all

// ---
bool XmlWriterExample()
{
	// some variable
	core::stringw characterName = L"Dom Fernando" ;

	// init writer
	irr::io::IXMLWriter* writer =  irrlichtDevice->getFileSystem()->createXMLWriter( targetFilePath )  ;
	if ( !writer ) { return false; } 

	// write xml header
	writer->writeXMLHeader(); 

	// write root node
	writer->writeElement( L"MyXmlRootNode",false); 
	writer->writeLineBreak(); 

	// write some variable
	writer->writeElement(L"CharacterName",true, L"value", characterName ); 
	writer->writeLineBreak(); 

	// close root node
	writer->writeClosingTag(L"MyXmlRootNode"); 
	writer->writeLineBreak(); 

	// dispose writer
	writer->drop() ; writer = 0 ;
	return true ;
}

I get something trouble when I used this

Code: Select all

writer->writeElement(L"CharacterName",false, L"value", characterName);

where characterName is variable that used to save text...
core::stringw characterName = "Hai";

but when I use this

Code: Select all

writer->writeElement(L"CharacterName",false, L"value", L"characterName");

there are no error...
the question is how can i save a text that saved before in variable... for example core::stringw characterName = "Hai"; ??
thanks[/code]

try this-

Code: Select all

writer->writeElement(L"CharacterName",false, L"value", characterName.c_str());

when i run this code, the first xml data was replaced by the second xml data, and the second replaced by the third, how i can make the xml data that the previous data will not replace by the newest one??

Unless you have worked it out since you last wrote, you could try and post your code so that it may help spot the problem.

It sounds like you want to append xml data to a file. You cannot do this directly using Irrlicht. You need to read the existing xml, and then write it back out, and then write the data you want to add.
