The split method treats adjacent > separators as one separator unlike the Perl and JDK 1.4 split functions. > That means it's not possible to join an array and then split the result > to get a similar array, that's quite annoying when manipulating CSV > records. For example: > > String[] tab1 = new String[] { "a", "b", "", "d" }; > > String[] tab2 = StringUtils.split(StringUtils.join(tab1, ';'), ';'); > > here tab2 = { "a", "b", "d" }, the 3rd element of tab1 is lost. > > That may be nice to have a flag on the split methods indicating if the > separators must be merged, or a new set of methods (slice()?) with the > same signatures and handling empty elements. > > Emmanuel Bourg > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED]
