I have a string that consists of several parts that are delimited with unreserved symbol.
eg. hyphen, underscore or tilde.
Like this: xxxxxxx_yyyyyyyy_zzzzzzzzz_wwwwww_qqqqqq
I want to get part between first and second underscore, then part between third and fourth underscore and so on...
How can i get only certain portion at the time of this string?
