regex for parsing html page by libcurl in c -


this question has answer here:

can give me regular expression in c parsing html page , extracting url links ?

the commenters have pointed obligatory link parsing general html regular expressions. same page has (not linked) answer says well-known subset can parsed regular expressions. i'm that.

if looking quick , dirty way list of hyperlinks in website, use

\<a [^>]*<href *= *"([^"]+)"

which should give link of <a href="..."> tags first grouped sub-expression each match. but:

  • obviously, there no context, regex match links commented out or part of javascript string or part of javascript comment.
  • regexes come in (too) many flavours. regex above works if \< means literal left angle bracket , < means boundary @ beginning of word.
  • the regex requires href attribute in double qoutes.

proceed carefully.

c++ - Why doesn't unordered_set provide an array access operator -

i'm curious why stl container unordered_set , has constant time complexity random access on average, not provide method accessing elements distance first element in container. example: t& unordered_set::operator[](size_t index) { return *(begin() + index); } accessing element "by distance" implies there meaningful way measure distance. trouble std::unordered_set is is, well, unordered . hence, there no meaningful way of explaining "some distance beginning" in non-arbitrary way. if want access distance, copy data vector: std::vector tmp(unordered.begin(), unordered.end());
