regex for vowels at word boundaries

I'm trying to match all words that satisfy the condition of having a vowel occur at the beginning and ending of a word.

What I tried (in JS so I could fiddle it):

var t = 'are ice apple cat dog'
var u =  t.match(/(\b[aeiou]\w+[aeiou]\b)+/); 
alert (u);  // should match 'are,ice,apple'

Give it the g global flag so it will match all. You could drop the outer ( )+, too, as it won't gain you anything.

var u =  t.match(/\b[aeiou]\w+[aeiou]\b/g); 
                                        ^

If you want to match all the words that satisfy a condition you need to at the 'g' modifier to your regexpression

var t = 'are ice apple cat dog'
var u =  t.match(/(\b[aeiou]\w+[aeiou]\b)+/g); 
alert (u);  // it now matches 'are,ice,apple'
