Cassandra,
The pipe is a special regular expression character. If you escape the pipe
(as I did in the attached file) you'll get the results that you expect.
% java TestSplit
Number with commas: 7
Number with pipes: 39
Number with pipes (escaped) : 7
Cheers,
Ed.

I am trying to split pipe delimited text using the Util.split() method.
However, instead of splitting the string based upon the pattern, it is
splitting the string along every character. I included a code example
below. When I split the pipe delimited string, I get 39 results. When I
split the comma delimited string, I get 7 results, which is what I want.
Does anyone have any suggestions?
Thank You,
Cassandra
