So, I am trying to extract the numbers with Regex Split using pattern:
Not sure whether the splitter is the most appropriate tool for that. One simple solution: Go for the String Manipulation node and do sth. like regexReplace($string$, "[^0-9]*", "") (strips everything which is not a number character)
[edit] Alternative RegEx for use with the splitter: [^\d]*(\d*).* (semantics a little different: strip away anything which is not a number from the beginning, match consecutive number characters, and after that strip away the rest)
