正如在构造正则表达式对象时我们可以指定选项如何处理正则表达式一样,在匹配的过程中我们依然可以指定另外的标志来控制匹配的规则。这些标志的具体含义,我从cppreference.com引用过来,用的时候查一下就可以了: 根据参数类型,于是我们构造了这样的调用: std::smatch results;regex_search(html,results,r); 1. 不过,标准...
The functions that take a match_results object set its members to reflect whether the search succeeded and if so what the various capture groups in the regular expression captured. Example C++ Копирај // std__regex__regex_search.cpp // compile with: /EHsc #include <regex> #...

regexec() is used to match a null-terminated string against the precompiled pattern buffer, preg. nmatch and pmatch are used to provide information regarding the location of any matches. eflags may be the bitwise-or of one or both of REG_NOTBOL and REG_NOTEOL which cause changes in match...
