Re: Perl regex. Why does this happen?

Why does this happen?

Because \s match all whitespace chars, including \n; thus \s{2} matches " \n" in your second line.

Based on the data you've provided, s[(\s{2})(?=\d)][2]g should do what you want.

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority". I knew I was on the right track :)

In the absence of evidence, opinion is indistinguishable from prejudice. Not understood.

Based on the data you've provided, `s[(\s{2})(?=\d)][2]g` should do what you want. Or (more simply, IMHO) use `\h` [horizontal whitespace] instead of `\s`	[reply] [d/l] [select]

If you want to be backward compatible, you can substitute `[^\S\n]` for \h. - tye	[reply] [d/l]
