public class Regex
extends java.lang.Object

A utility class for regular expression matching. Defaults to case-sensitive, multi-line matching. RegExps: http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html Groups beginning with (? are pure, non-capturing groups that do not capture text and do not count towards the group total. ---------------------------- FLAGS ----------------------------- Embedded Compiled Meaning * (?i) Pattern.CASE_INSENSITIVE Enables case-insensitive matching. (?d) Pattern.UNIX_LINES Enables Unix lines mode. (?m) Pattern.MULTILINE Enables multi line mode. (?s) Pattern.DOTALL Enables "." to match line terminators. (?u) Pattern.UNICODE_CASE Enables Unicode-aware case folding. (?x) Pattern.COMMENTS Permits white space and comments in the pattern. --- Pattern.CANON_EQ Enables canonical equivalence. ----------------------------------------------------------------
