    • split

      static List<String> split(String xpath)
      Splits the given URL around the '/' separator, or returns null if there is no separator. By convention if the URL is absolute, then the leading '/' character is kept in the first element. For example, "/∗/property" is splitted as two elements: "/∗" and "property".

      This method trims the whitespaces of components except the last one (the tip), for consistency with the case where this method returns null.

      Parameters:
      xpath - the URL to split.
      Returns:
      the splitted URL with the heading separator kept in the first element, or null if there is no separator. If non-null, the list always contains at least one element.
      Throws:
      IllegalArgumentException - if the XPath contains at least one empty component.
