Well, your pattern in #1 doesn't represent what you say in #2. The following pattern will do what you describe in #2:
/[a-zA-Z0-9_]+(?=\.?[a-zA-Z0-9_]*)/g; and can be shortened into: /\w+(?=\.?\w*)/g; It will return an array that contains "consequtive sequences of word characters [a-ZA-Z0-9_] optionally followed by a dot and more word characters." The lookahead assertion (?=) doesn't consume the characters in the second part of the pattern so your objectB string makes it through. Keep in mind that this pattern will not work against your previous example of '*&%*&^objectA()*&)(*&908objectB,objectC'. My original pattern will though.
