The MatchRegex Node.
The MatchRegex Node allows one to search a String for a certain pattern, which can be given as a regular expression. The part of the String in which the search is performed can be customized with the indices of the beginning and end of the search, which are given to the Node either as Attributes or Inputs. The Node outputs the result as a Boolean, together with the index of the first appearance of the searched pattern and the number of matches.
