Xerces C++ SAX Parsing Problem: expected class-name before '{' token
- by aduric
I'm trying to run through an example given for the C++ Xerces XML library implementation. I've copied the code exactly, but I'm having trouble compiling it.
error: expected class-name before '{' token
I've looked around for a solution, and I know that this error can be caused by circular includes or not defining a class before it is used, but as you can see from the code, I only have 2 files: MySAXHandler.hpp and MySAXHandler.cpp. However, the MySAXHandler class is derived from HandlerBase, which is included.
MyHandler.hpp
#include <xercesc/sax/HandlerBase.hpp>
class MySAXHandler : public HandlerBase {
public:
void startElement(const XMLCh* const, AttributeList&);
void fatalError(const SAXParseException&);
};
MySAXHandler.cpp
#include "MySAXHandler.hpp"
#include <iostream>
using namespace std;
MySAXHandler::MySAXHandler()
{
}
void MySAXHandler::startElement(const XMLCh* const name,
AttributeList& attributes)
{
char* message = XMLString::transcode(name);
cout << "I saw element: "<< message << endl;
XMLString::release(&message);
}
void MySAXHandler::fatalError(const SAXParseException& exception)
{
char* message = XMLString::transcode(exception.getMessage());
cout << "Fatal Error: " << message
<< " at line: " << exception.getLineNumber()
<< endl;
XMLString::release(&message);
}
I'm compiling like so:
g++ -L/usr/local/lib -lxerces-c -I/usr/local/include -c MySAXHandler.cpp
I've looked through the HandlerBase and it is defined, so I don't know why I can't derive a class from it? Do I have to override all the virtual functions in HandlerBase? I'm kinda new to C++.
Thanks in advance.
