The <replace> task (one of the standard tasks) will do an "inline" (i.e., within the same file) search-and-replace for arbitrary strings. You could fake filtering-type behavior by doing a <copy> and then a <replace>.
The <rereplace> task I submitted a couple of weeks ago (check the archives) will do the same thing as <replace>, except it will find an arbitrary regular _expression_ and replace it with another (possibly based upon the "found" _expression_).
