If someone is in need to parse URIs, then the following regex handle it:

    | regStr regex |

    regStr :=     
        '((([a-z]\w+\:)',                     "Match URL protocol and colon"
        '(/|//|///|[A-Za-z0-9%]))',          "Match 1-3 slashes or single letter or digit or %"
        '|',                                 "or"
        '(((www\d)|(www\d\d)|(www\d\d\d))[.])',    "match www ou www[1-999] followed by ."
        '|',                                   "or"
        '([A-Za-z0-9._\-]+[.]([a-z][a-z]|[a-z][a-z][a-z]|[a-z][a-z][a-z][a-z])/))', "domain name"   
        '(([^\s()<>]+',                      "run of non-space, non ()<>"
        '|',                                 "or"
        '\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+)', "balanced parens up to two levels"
        '(\(([^\s()<>]+|(\([^\s()<>]+\)))*\)',   "end with balanced aprens up to 2 levels"
        '|',                                 "or"
        '[^\s`!()[]{};:''".,<>?«»“”‘’])'.    "not a space or one of these punct chars"
                   
    regex := RxMatcher forString: regStr.
