First, as you see, from my example, capturing parenthesis do not work, i.e., the string is not splitted according to what I intended to be a separator: 'abc'.
Second, you said "if you want to keep the stuff you split on"... Yes, this is what I want, but,
please don't tell me that "the way you are trying it will never work". Of course, I know that, and this is the reason I'm posting a question here.
By the way, I'm new here, and I understood this is the site to ask for some help, if it isn't, please tell me where to go with my silly questions.
