我正在尝试使用以下语法解析测试结果的日志文件。
template<typename Iterator>
struct test_step_parse: qi::grammar<Iterator, TestResults(), ascii::space_type> {
test_step_parse() : test_step_parse::base_type(rqmts) {
    using qi::lit;
    using qi::lexeme;
    using qi::omit;
    using qi::int_;
    using qi::eol;
    using qi::char_;
    test_step = lit("Test Step No.") >> int_;
    pass_or_fail = lit("-") >> (string("Passed") | string("Failed"));
    fdor_rqmts = -lit("OID")
                 >> lit("FDOR")
                 >> -lit("OID")
                 >> int_
                 >> *(-omit[char_(",/\\")] >> -(lit("FDOR") ^ lit("OID")) >> int_)
                 ;
    sard_rqmts = -lit("OID")
                 >> lit("SARD")
                 >> -lit("OID")
                 >> int_
                 >> *(-omit[char_(",/\\")] >> -(lit("SARD") ^ -lit("OID")) >> int_)
                         ;
    comment = lit("Comment:") >> lexeme[*(char_ - eol)] ;
    rqmts =  test_step
             >> pass_or_fail
             >> omit[*(char_ - lit("REQUIREMENT VERIFIED:"))]
             >> lit("REQUIREMENT VERIFIED:")
             >> (fdor_rqmts ^ sard_rqmts)
             >> omit[+char_("=")]
             >> -comment
             ;
    BOOST_SPIRIT_DEBUG_NODE(test_step);
    BOOST_SPIRIT_DEBUG_NODE(pass_or_fail);
    BOOST_SPIRIT_DEBUG_NODE(fdor_rqmts);
    BOOST_SPIRIT_DEBUG_NODE(sard_rqmts);
    BOOST_SPIRIT_DEBUG_NODE(comment);
    BOOST_SPIRIT_DEBUG_NODE(rqmts);
}
qi::rule<Iterator, TestResults(),  ascii::space_type> rqmts;
qi::rule<Iterator, int(), ascii::space_type> test_step;
qi::rule<Iterator, std::string(), ascii::space_type> pass_or_fail;
qi::rule<Iterator, std::string(), ascii::space_type> comment;
qi::rule<Iterator, std::vector<int>(),  ascii::space_type> fdor_rqmts;
qi::rule<Iterator, std::vector<int>(),  ascii::space_type> sard_rqmts;
};
语法分析正常。但是,当尝试自动填充我的用户定义结构时,std::string 类型的规则“comment”的属性被作为 ascii 数字传递到向量中。
这是我的用户定义结构:
struct TestResults {
    int test_step_no;
    std::string pass_or_fail;
    std::vector<int> FDOR;
    std::vector<int> SARD;
    std::string comment;
}; 
BOOST_FUSION_ADAPT_STRUCT(
    atp::TestResults,
    (int, test_step_no)
    (std::string, pass_or_fail)
    (std::vector<int>, FDOR)
    (std::vector<int>, SARD)
    (std::string, comment)
)
调试输出表明规则公开了正确的类型,但不知何故,它们没有正确放置在结构中。
任何想法我做错了什么?对任何滥用术语等表示抱歉。
使用 gcc 4.6.3 并提升 1-47。谢谢你。
更新:为了澄清,所以我期待解析以下内容:
std::string test_test =
"Test Step No. 953-Failed\n"
"==============================================================================\n"
"STEP 7.7:\n"
"Test step, etc.\n"
"===============================================================================\n"
"REQUIREMENT VERIFIED: FDOR 12345"
"                      SARD 12345, 12356\n"
"===============================================================================\n"
"Comment: Didn't work.\n"
;
使用调试器,似乎所有规则都正确地公开了它们的属性:
<rqmts>
  <try>Test Step No. 953-Fa</try>
  <test_step>
    <try>Test Step No. 953-Fa</try>
    <success>-Failed\n============</success>
    <attributes>[953]</attributes>
   </test_step>
   <pass_or_fail>
    <try>-Failed\n============</try>
    <success>\n===================</success>
      <attributes>[[F, a, i, l, e, d]]</attributes>
      </pass_or_fail>
     <fdor_rqmts>
     <try> FDOR 12345         </try>
         <success>                    </success>
         <attributes>[[12345]]</attributes>
    </fdor_rqmts>
    <sard_rqmts>
        <try>                    </try>
        <success>\n===================</success>
        <attributes>[[12345, 12356]]</attributes>
   </sard_rqmts>
   <comment>
       <try>Comment: Didn't work</try>
       <success>\n</success>
       <attributes>[[D, i, d, n, ', t,  , w, o, r, k, .]]</attributes>
  </comment>
  <success>\n</success>
       <attributes>[[953, [F, a, i, l, e, d], [12345], [68, 105, 100, 110, 39, 116, 32, 119, 111, 114, 107, 46], []]]</attributes>
 </rqmts>
所以一切似乎都在工作,除了“评论”属性(std :: string)被填充在“SARD”属性(vector)中,作为ascii数字的向量,即,
[68, 105, 100, 110, 39, 116, 32, 119, 111, 114, 107, 46] = "Didn't work."
