REGEX is not exactly my favorite technology to have to work with, but there are times when it is definitely the right tool for the job. Recently I needed to parse a large text file that contained blocks of information within curly brackets - {}.

I found a great solution for the REGEX at:

Note that balancing groups is only in the Microsoft REGEX classes... if you are using a different library you may have to follow an alternative, less powerful route where you know the number of levels that may be used: http://blog.stevenlevithan.com/archives/regex-recursion

KUDOS to Steve...

My final solution by the way was:
@"\{(?>[^{}]+|\{(?)|\}(?<-Depth>))*(?(Depth)(?!))\}" Posted on Saturday, January 17, 2009 5:05 PM | Back to top
