C Regex Get Elements Inside Expression Stack Overflow After setting up the standard calls (and checks) for regcomp ( ) and regexec ( ), i can only manage to print the actual substrings that match my compiled regular expression. using regexec, according to the manual pages, means you store the substring matches in a structure known as "regmatch t". What is the regular expression to extract the words within the square brackets, ie. note: in my use case, brackets cannot be nested. you can use the following regex globally: \[(.*?)\] explanation: \[ : [ is a meta char and needs to be escaped if you want to match it literally. (.*?) : match everything in a non greedy way and capture it.

The safest approach here is to use an actual parser here to locate c elements. if 100% correctness is not a goal though then a regular expression will work because it can be crafted to catch the majority of cases within a code base. In general, the following regular expression fragment is what you are looking for: "(.*?)" this uses the non greedy *? operator to capture everything up to but not including the next double quote. then, you use a language specific mechanism to extract the matched text. in python, you could do:.

Creation of regular expression for compiling or creating the regular expression regcomp () function is used. it takes three arguments: syntax: regcomp(®ex, expression, flag) where, regex is a pointer to a memory location where expression is matched and stored. expression is a string type flag to specify the type of compilation. 2 regex noob here i have the following string: this is a message {key1} {{key2}} {{{key3}}}, and includes {key4}. i'm trying to extract anything between the outer curly braces. expected matches: key1 {key2} {{key3}} key4 most so examples cover matches on a single curly brace or a double curly brace, but not both or any variation of. That said, you've already got a working regular expression. just make sure to retrieve the capture group #1. that will get you just what is inside the first pair of parentheses. if you're using c#, instead of calling tostring() on the match, look into its groups property and get its first element: string pattern = "
