regular expression as delimiter in PigStorage?

[lei tang]

Hi,

Is it possible to use a regular expression as a delimiter to load a data,
say sth. like
A = load 'data' using PigStorage('\s+');

However, by checking the doc, it seems that only one character is accepted
as the delimiter.
http://pig.apache.org/docs/r0.10.0/api/org/apache/pig/builtin/PigStorage.html

Just wondering whether there is any way to achieve similar goal  as the
command above.  BTW,  I'm using Pig 0.10.0.

Thanks,
- Lei
