Regex Capturing Groups In C Stack Overflow Here's a version that captures multiple groups in multiple matches. char * source = " abc123def ghi456 "; char * regexstring = "[a z]*([0 9] )([a z]*)"; size t maxgroups = 3; regex t regexcompiled;. I am trying to get capture groups working properly in c. i am pretty comfortable with how regex works, but for some reason, i can't get capture groups to works like i expect them to. surely, it is me, doing something wrong, but i don't quiet know what. see the following example: char* pattern2 = "^(\\d )\\s\\s :\\s \\s.*\\((\\s )\\)$";.
Regex Capturing Groups In C Stack Overflow Capturing groups allow you to treat a part of your regex pattern as a single unit. this is especially useful when you want to apply quantifiers or modifiers to multiple characters or. In the flavor you can have several groups sharing the same name, they will use capture stacks. in pcre you have to explicitly enable it by using the (?j) modifier (pcre dupnames), or by using the branch reset group (?|). A short introduction into the syntax of regular expression groups that can be used for very common data transformation tasks. i personally often need them, when i use data from excel and need to extract something and put it into a list of strings, to use it for example in an sql query like: name column a b c. Capture groups must be escaped in a basic posix regex. this can be fixed by using reg extended. the *? non greedy operators is an enhanced non posix feature borrowed from perl. you get them with reg enhanced. but don't try to parse json with a regex for all the same reasons we don't parse html with a regex. use a json library such as json glib.
