please consider the following javascript code:
"myObject.myMethod();".replace(/\.\w+\(/g, "xxx");
it gives "myObjectxxx);" as ".myMethod(" is selected.
Now I would only select myMethod instead. In other words I want to select any word starting with . and ending with ( (excluded).
Thanks, Luca.

To use RegEx, the first argument of replace will be replaced with regex syntax, for example /regex/ . This syntax serves as a pattern where any parts of the string that match it will be replaced with the new substring. The string 3foobar4 matches the regex /\d.
For example, the replacement pattern $1 indicates that the matched substring is to be replaced by the first captured group.
How do you ignore something in regex? To match any character except a list of excluded characters, put the excluded charaters between [^ and ] . The caret ^ must immediately follow the [ or else it stands for just itself.
General answer: Capture the part that you want to keep with parentheses, and include it in the substitution string as $1.
See any regexp substitution tutorial for details.
Here: just include the . and the ( in your substitution string.
For an exercise, write a regexp that will turn any string of the scheme --ABC--DEF-- to --DEF--ABC-- for arbitrary letter-values of ABC and DEF. So --XY--IJK-- should turn into --IJK--XY--. Here you really need to use capture groups and back references.
