I am trying the second exercise, I have this ^(img_) (jpg|png|gif)$ cannot seem to validate the middle part. Thank you in advance! Match:
img_01.jpg img_02.png img_03.gif img_04.png img_05.gif img_06.jpg
Exclude: mov_01.avi

6,047 PointsIn case you are still curious, what you typed doesn't validate the middle part because the middle part isn't typed. The ^ includes everything after it, including the (jpg|png|gif), while the $ includes everything before it, including the (img_). Think of the ^ and the $ like quotes in the specific way that you have used it. So you effectively have told the computer to search for literally (img_)(jpg|png|gif) with no exceptions, which means nothing with a "middle part" will show up.
An alternative (and perhaps overly simplified) way to search would be something like ^(img_)....(jpg|png|gif)$
You could also do something like ^(img_)_\d{2}.(jpg|png|gif)$ to be extra specific.
Hope that helps!
