copied!<p>Regex for capturing strings (with <code>\</code> for character escaping), for the .NET engine:</p> <pre><code>(?>(?(STR)(?(ESC).(?<-ESC>)|\\(?<ESC>))|(?!))|(?(STR)"(?<-STR>)|"(?<STR>))|(?(STR).|(?!)))+ </code></pre> <p>Here, a "friendly" version:</p> <pre><code>(?> | especify nonbacktracking (?(STR) | if (STRING MODE) then (?(ESC) | if (ESCAPE MODE) then .(?<-ESC>) | match any char and exits escape mode (pop ESC) | | else \\(?<ESC>) | match '\' and enters escape mode (push ESC) ) | endif | | else (?!) | do nothing (NOP) ) | endif | | -- OR (?(STR) | if (STRING MODE) then "(?<-STR>) | match '"' and exits string mode (pop STR) | | else "(?<STR>) | match '"' and enters string mode (push STR) ) | endif | | -- OR (?(STR) | if (STRING MODE) then . | matches any character | | else (?!) | do nothing (NOP) ) | endif )+ | REPEATS FOR EVERY CHARACTER </code></pre> <p>Based on <a href="http://tomkaminski.com/conditional-constructs-net-regular-expressions" rel="noreferrer">http://tomkaminski.com/conditional-constructs-net-regular-expressions</a> examples. It relies in quotes balancing. I use it with great success. Use it with <code>Singleline</code> flag.</p> <p>To play around with regexes, I recommend <a href="http://www.radsoftware.com.au/regexdesigner/" rel="noreferrer">Rad Software Regular Expression Designer</a>, which has a nice "Language Elements" tab with quick access to some basic instructions. It's based at .NET's regex engine.</p>
