Maybe something along the following lines...

struct Wrapper {
    XML_Parser m_parser;

    void init(
      const XML_Char* encoding,
      const XML_Char* seperator) {
      m_parser = XML_ParserCreate_MM(
        encoding,
        0,          // memsuite
        seperator); // namespace seperator

     if (!m_parser)
	return;

     // Set the user data used in callbacks
     XML_SetUserData(m_parser, (void *) this);
   }
   void fini() {
    if (m_parser)
        XML_ParserFree(m_parser);
    m_parser = 0;
  }
  bool parse(
    const char* buffer,
    int length,
    bool isFinal) {
    assert(m_parser != NULL);

    // get the length if not specified
    if (length < 0)
        length = strlen(buffer);

    // invoke the parser
    return XML_Parse(m_parser,buffer,length,isFinal)!=0;
  }
  ...
};

Hope it helps,
Ali
