I'm looking for a diff tool that will allow me to compare just a sub-section of a file with a section of another file, or even of itself. Preferably eclipse based but will take all suggestions.

Yes I know I can copy out the two sections into different files and compare those, but that is very tedious when you are trying to do a large amount of refactoring.

Basically I'm trying to remove as much duplicated code as possible from a code base that is suffering from a great deal of ctrl-V 'inheritance' ;-) However the pasted parts have evolved apart a little over time.

Currently I am using google-diff-match-patch to implement a real-time editing tool, which can synchronize texts between multiple users.
