salutations, I'm a complete beginner in Regex++; I've downloaded it and installed it in Visual C++ 6.0, and it's functioning properly. the problem is that I searched all over the internet and I only discovered how to do basic matching operations and basic replacing. my doubt is the following: I want to know how to do search and replace regexp operations, like it can be done in Perl by using groups (expressions surrounded by parentheses), which allow to select the substrings, matched by the regexp, in the form of $1, $2, and so on. basically, the parentheses mark the matched expression for future reference (for example, for use in the replace operation). for example (Perl example): s/X(.*?)Y/XY$1/g; I'm not sure if this explanation of what I want is very clear. I would appreciate a straightforward example code. thank you in advance. -- View this message in context: http://www.nabble.com/-C%2B%2B--Boost%3A%3ARegex-beginner-question-tp2108174...
