The Regex() function in Media Center's expression language supporting regular expression pattern matching is implemented using external regular expression libraries.
Media Center 19
In Media Center 19, the Regex() function is implemented using the Boost C++ library, version 1.54. While Boost supports several flavors of regular expressions, the mode enabled in Media Center is the Perl Regular Expression Syntax.
Media Center 18 and earlier
In Media Center 18 and earlier, the Regex() function was implemented using the Microsoft 2010 TR1 engine.
