Regular Expressions question?

Question

Does anyone know how to write a regular expression to match a word containing all the vowels (a,e,i,o,u) in order?

Answer 1

Thats going to be really tough man.

Answer 2

Ignoreing word boundaries and casing - just because it makes it even more of a mess - and using the most common forms, perhaps:



[a-z]*a[a-z]*e[a-z]*i[a-z]o[a-z]*u[a-z]*

Answer 3

It depends on the language/tool you're using, but this pattern will work with most good regex tools:

\b\w*a\w*e\w*i\w*o\w*u\w*\b
