Hello,
I know need some help with regex I am not very smart when it comes to figuring this out but I will get there.
My question:
I need to remove banner sizes from a string,
banner sizes can be 486X60 or 49 X 120
How can I use regex to replace this with blank?
The basic idea is something like
1 or more digits a space (optional) X another space (optional) 1 or more digits
The exact syntax depends on what language you're using, but it would look something like
s/\d+[ ]?X[ ]?\d+//
or, if you want to be sure that the X either has spaces on both sides or none at all, you can separate the two cases:
s/(\d+ X \d+)|(\d+X\d+)//
This will cover exactly the two example cases you mentioned. If you want to allow any amount of whitespace around the X, or allow the X to be lower case, chaos's solution covers that.
