Are regular expression questions not welcome at SO? Why? Here are two threads:
I replied to this unanswered four month old question only to receive immediate down votes with the explanation that the user shouldn't be using regex. I don't discount that advice for certain scenarios, but the user wanted a regex answer and was given one.
Then there is this question where it was closed after one hour
I replied to the user to try the MSDN regex forum in the comments since the post was closed. Learning regular expressions creates questions...just like .Net C# linq, but you don't see those questions closed. (Should that question be moved to code review instead?)
Now two questions don't indicate a pattern, but something is amiss when it comes to regex. Learning regex requires asking questions...to which Stack Overflow seems like an appropriate place to ask them.
Am I wrong?
I get that people have personal preference to not use regular expressions and that is fine; but when moderators or persons of stature apply their bias in Stack Overflow I believe that goes against the spirit of Stack Overflow.
