What is a regex with a touch of greed in its capture

I am considering the following options:

  1. ' !This is a string! '
  2. '!This is a string !'
  3. '! This is a string !'
  4. ' ! This is a string! '
  5. ' ! This is a string '

For each of these scenarios, I aim to find a match for:

'This is a string'

Here's what I have attempted so far:

/\s*!(.*)!{0,1}
/\s*!(.*?)!{0,1}

However, it seems to either include the ! or not match at all. Keep in mind that the trailing ! is optional.

Check out this fiddle to better understand my issue

Answer №1

Perhaps consider this option

/^\s*@\s*(.*?)\s*@?\s*$/

Answer №2

Is this regular expression suitable for addressing your issue?

^[\s!]*(\w*)[\s!]*$

Answer №3

Give this a shot:

(\b.*\b)

This expression utilizes \b, which represents word boundaries.

Check out the JSFiddle demonstration.

Answer №4

Can I safely assume that the string will not contain any exclamation marks? If so, you could use this pattern:

/\s*![^!]*!{0,1}/

Answer №5

Alright, I have a solution that maintains the exclamation mark at the end:

/(?:^[^a-z0-9]*)(.*?)(?:\s*)$/i

Here is the link to it: http://jsfiddle.net/UAefq/4/

If you want to remove the exclamation mark and spaces at the end of the string, you can modify it like this:

/(?:^[^a-z0-9]*)(.*?)(?:[\!\s]*)$/i

You can see the updated version here: http://jsfiddle.net/UAefq/5/

I hope this fully addresses your question.
