Regular Expression to search for double occurence of a pattern

Hi

What would be the best method to search a string for double occurance
of a pattern.

Ex: set mystr "my name is your name only"

now i have the word "name" occuring twice in 'mystr'.
What is the method to count the occurance of word "name" ?
or if i want to make sure it occurs twice what is the method ?

Thanks
Arun
