RegExp Interface
RegExp represents regular expressions.
firstMatch is the main implementation method that applies a regular expression to a string and returns the first Match. All other methods in RegExp can build on it.
Use allMatches to look for all matches of a regular expression in a string.
The following example finds all matches of a regular expression in a string.
RegExp exp = const RegExp(@"(\w+)");
String str = "Parse my string";
Iterable<Match> matches = exp.allMatches(str);
