I think Michael Yudchak's downvote a little unfair. His written English could have been better but his question I think was still valid.
The example usage given by Step 5 of the tutorial gives an example of using "xmlEffect.h" without explaining where it comes from or what it is:
#include "xmlEffect.h"
int main(void)
{
char c;
xmlSetting xmlset;
xmlset.saveEffectXML("test.xml","child1","child2","3000","4000");
xmlset.loadEffectXML("test.xml");
c=getchar();
}
The solution therefore is to follow the first four steps, as it says, but ignore Step 5 and just try out an example of your own. Example minimalist "Hello World" example:
Example XML: test.xml
<?xml version="1.0" ?>
<Hello>World</Hello>
Example code: main.cpp
#include "tinyxml.h"
#include <string>
int main()
{
TiXmlDocument doc( "test.xml" );
if ( doc.LoadFile() )
{
TiXmlElement* element = doc.FirstChildElement( "Hello" );
std::string text = element->GetText();
}
return 0;
}
