Question

I have an NSArray of lines (objective-c iphone), and I’m trying to find the line which starts with a number, followed by a dot and a space, but can have any number of spaces (including none) before it, and have any text following it eg:

    1. random text
           2. text random
3.

what regular expression would I use to get this? (I’m trying to learn it, and I needed the above expression anyway, so I thought I’d use it as an example)

Answer 1

With C#:

@"^ *[0-9]+\. "

It doesn’t check for the presence of something after the ., so this is legal:

1.(space)

If you delete the @ and escape the \ it should work with other languages (it is pretty “down-to-earth” as RegExpes go)
