Regular expression for pepper+tomato+watermelon

Question

Regular expression for something+something+something ... +something?

Sorry because of my great english and brain -> keyboard connection

Answer 1

If the "something" is always a word and needs at least two entries

\w(\+\w)+

or for any repeating sequence

\w(\+\w)*

Answer 2

([a-zA-Z]+(\+[a-zA-Z]+)*)

Answer 3

You just have to escape the '+' and the '.' as they are reserved.

For example, in ruby:

/something\+something\+something \.\.\. \+something/

Answer 4

You can escape the + metacharacter using \+ in your regular expression, if that's what you're asking.

Answer 5

Based on the comment clarifying the question, here's an updated answer:

([a-z]+\+)*[a-z]+

or

[a-z]+(\+[a-z]+)*

Answer 6

As an alternative, would a string split method work?

"Or+Something+like+that".split('+')

Answer 7

/\w+(\s*\w+)*(\+\w+(\s*\w+)*)*/

This should also match phrases of multiple words, if you need that. It also matches non-alpha characters, but you can replace \w with [a-z] if you explicitly want to exclude everything but letters. Just make sure you specify the regex to be case insensitive if you expect capital letters.

edit: commenter below noticed I didn't have the plus sign after the \w 's, so it was only matching a single character at a time. \w+ will match entire words, with an optional space in between, which was the original intention. Thanks for the catch.
