Amazing Tutorial, was searching to test this RegExp
can any help me understand, how does that translates to ?
(?:+)?1?(.{1,100})
Hey Derek, thank you so much for this tutorial and all of your other ones! I had a very shaky grasp on regex and I think I understand it a lot better now. Correct me if I'm wrong though, but doesn't w also include numbers in addition to letters (as in, alphanumeric)? Some sites say this but I'm not sure if its just specific to a certain language or something.
Great job! It is very well explained. (Subscribed!)
brilliant tutorial!!
MY MAN!!!!!! YOU JUST HELPED ME FINISH MY BIG PROJECT!!!! THANK YOU SO MUCH!

Thank you very much for your tutorials. I have found them to be some of the best on YouTube for helping me understand and use Regular Expressions!

Hello Derek,
I need your help.
I have a .txt file which looks like :
2017-06-22 23:19:05,758 use database stocks
2017-06-22 23:21:27,056 CREATE TABLE stocksdata ( stock_exchange string,
stock_symbol string, date TIMESTAMP,
The regex I wrote is '^(\d{4}-\d{2}-\d{2})\s+(\d{2}:\d{2}:\d{2}),(\d{3})\s((?i)(create|select|use).*)$'
But my output is
2017-06-22 23:19:05,758 use database stocks
2017-06-22 23:21:27,056 CREATE TABLE stocksdata ( stock_exchange string,
It is not taking lines in next line of input.
Can you please help me out.
Well I've been spelling Calendar wrong my entire life.
after watching this tut i definitely took a deep breath of relief
thanx
So helpful. Thank you, I look forward to checking out the rest of these videos.
Using regex at the moment, in Calibre, to fix some ebooks with messed up formatting. Removing all </p> that were placed in the middle of a sentence, removing page numbers etc. It's actually quite satisfying.. 🙂
please tell me how to remove lines in java script files like
which starts with //
like
// Create a reference to the jQuery DOM object
var $this = $(this);
$this.data('uploadifive', {
inputs: {}, // The object that contains all the file inputs
how i do make for urdu language?
Thanks for doing this! Very clear explanation wow!
we get it. Its very simple with regular expressions please stop saying it, stahhhhp!!!
I'm gonna cry.Thank you so much.. Life saver
Awesome. Thanks for the video
Can you suggest me some books for regex
Amazing
Your tutorials are crystal clear, and have helped me a lot in my full stack journey! Cheers and thanks!
Wow you sound so different.
I rarely give likes to videos. But this is surely one.
There are things that are easy to learn, those that take a lot of time to learn and then there are those special languages, scripts or codes that just do not make sense…. and no matter the amount of searching and endless hours watching tuts or reading articles, you end up more confused. RegEx being one and the other, for me, is Cross-domain proxy bypass. Thanks to Derek, just from this first part, he connected almost all the dots in such a clear and simple way. I have a feeling you have just saved me many hours of headaches. 2000 thanks! By chance, do you have a tut on cross domain proxy bypass 😀 Off to part 2, Cheers!
Thanks!
Beautifully explained! Thank you sir
Thank you so much. <super tutorial>
In less than 4 minutes, I fell in love with your style ;-P Keep up the good work. Thank you!

M CNFUSED .. wats the answer of the question?" Why regular expressions are used in token specification? Write the regular expression to specify the identifier like in C. "
Excellent video!!
I'm new to Regular Expressions, but looks powerful. Have you got any good examples of extracting info from DisplayName ie FirstName value (usually separated by a space). I just need to pull the first names out.
By far the best tutorial I have seen on this. This video has really helped me with my understanding. Thank you for doing this.
Really awesome tutorial! thank you
