Substitution problem

Hi,

I’d like to capitalize every word in a string.

I was hoping this expression would do it:

newstr = str.gsub(/\b(\s)?([a-z])/,‘\1\2’.upcase)

but it turns out that as \2 is not evaluated right away,
the .upcase has
no effect. Suggestions?

how 'bout the block form?

newstr = str.gsub(/\b(\s)?([a-z])/) { |s| s.upcase }

that works for me.

Regards,
Barry

Or

newstr = str.gsub(/\w+/) { |s| s.capitalize }

Thanks guys,

Barry, I like yours the best as it’s closet to mine and because you’re
not using capitalize. Capitalize actually changes all other letters in a
word to be lowercase, which isn’t always desired.

Thanks very much all.
