try the new "Tokenizer" class.  You can get it from CVS.

Subject: [lang] StringUtils.split() functionality wrt separator repeats


The StringUtils.split(), suggest as an alternative to StringTokenizer, 
ignores adjacent separators.
However, I feel that it would be better if they were not ignored, and empty 
strings be returned when such a case occurs. Or, there be an overloaded 
option which lets the user specify whether to ignore separator repeats or 
not.

As I see it, it is more often that a separator repeat occurs due to the 
absence of data in a specified series of, say, cells. Taking the typical 
case of a CSV file line read, finding two commas would mean a cell is empty,

not that the resultant array should have one element less. It must rather 
have the expected number of elements with the repeat case entailing an empty

String.
Comments.
