Thanks for the suggestions and advice : however I hope my english is
adequate enough to make myself understood in this NG :-))

I have the problem of 'filtering' a text file, exported from Excel as a
'Windows text file with <return>', containing <tabs> between numbers.
So, besides converting all comma to points, I have to get rid af all
<tabs> and after that, reduce all spaces between words to one space.
So far its working : I have used the preg_split first with /\t/ then
/\s+/ in two separate steps. No problem so far.
If they arise, I'll come back again.

I can't. I need the numbers and they may be decimals with points.
