使用Rapidxml在cpp中解析xml文件时出错

Question

我正在尝试阅读和xml文件并使用以下代码解析它可以有人建议我犯了什么错误。

显示错误

  

错误：（E549）未捕获异常：ConfigException：expected＆lt;

void ParserCnfFile::read(void) {
    ifstream file(m_file.m_name.c_str(), ios::in | ios::binary | ios::ate);
    if (file.is_open()) {
        file.seekg(0, ios::end);
        int size = file.tellg();
        m_file.m_contents = new char[size];
        file.seekg(0, ios::beg);
        file.read(m_file.m_contents, size);
        file.close();
    } else {
        throw ConfigException("ConfigExpection: Could not open \"" +
                              m_file.m_name + "\"");
    }
}

void ParserCnfFile::parse(void) {
    xml_document<> doc; // character type defaults to char
    try {
        doc.parse<0>(m_file.m_contents);
        flags
    } catch (rapidxml::parse_error& e) {
        cout << m_file.m_contents << endl;
        throw ConfigException(string() + "ConfigExpection: " + e.what());
    }

    xml_node<>* rootNode = doc.first_node();
    xml_node<>* node = rootNode->first_node();
}

这是我的xml文件。
