multiple replace operations on selected parts of java code ?

Hi,

i very often have to do some steps for this:

from

String lala = "Such a boring Question about a simple Replace-Operation";

to

public static String lala = error_such_a_boring_question_about_a_simple_replace_operation="error_such_a_boring_question_about_a_simple_replace_operation";

Is there a plugin to do some sed operations or so with a text selection, to be undependent and use tools like sed, grep and so on on text selections ?
