Use the GWT RegExp class. The following gets all the matching strings:
// does what I think you were looking for
String pattern = "(abc)|(def)";
String input = "abczdefzabc";
RegExp regExp = RegExp.compile(pattern, "g");
MatchResult matcher = regExp.exec(input);
// could probably use a doWhile to make it simpler
while(matcher!=null) {
System.out.println( "Found match str: "
+matcher.getGroup(0) );
matcher = regExp.exec(input);
}
Sincerely,
Joe
