Any standard library implementation for boost::property tree

Is there an alternative to to "boost/property_tree" ?

Actually I'm trying to remove all boost implementations of C++ and use standard library functions. I've been able to find alternatives to some other implementations of boost C++ but none so for property tree.

Motivation to not use boost: Mostly dealing with added dependencies

bool Processor::init(std::istream& xml, std::istream& rioxml, const std::string& logconfig, const std::string& recoveryConfig) {
    boost::property_tree::ptree config;
    boost::property_tree::ptree rioconfig;
    try {
        boost::property_tree::xml_parser::read_xml(xml, config,
                boost::property_tree::xml_parser::no_comments);

        boost::property_tree::xml_parser::read_xml(rioxml, rioconfig,
                boost::property_tree::xml_parser::no_comments);

        return Initialize(config, rioconfig, logconfig, recoveryConfig);
    }
    catch(const boost::property_tree::xml_parser::xml_parser_error& ex){
        LOG_ERROR(LOGCAT_DEFAULT, MSGID_UNKNOWN, "Failed to parse business config: " << logconfig);
        return false;
    }
}
