Copy specific files and keep the subfolder structure I got a folder with a large amount of files with different suffixes in several sub folders.

My automator workflow works as follows:


Ask for Finder Items
Get Folder Contents (sub folder option checked)
Filter Finder Items (for a specific file-suffix)
Copy Finder Items


This works like a charm. But all files are copied in the same root destination folder. I need to keep the the sub folder structure. For Example:

sourceFolder
    subfolderA
        fileA.jpg
        fileB.xls
        fileC.xls
    subfolderB
        fileC.jpg
        fileD.xls
        fileE.xls


Expected result (filter for file suffix .xls):

destinationFolder
    subfolderA
        fileB.xls
        fileC.xls
    subfolderB
        fileD.xls
        fileE.xls


Current result:

destinationFolder
    fileB.xls
    fileC.xls
    fileD.xls
    fileE.xls


Update

I'm a developer. So a shell or AppleScript will be also accepted. :)
rsync -avh --include='*/' --include='*.xls' --exclude='*' path/to/sourceFolder/ path/to/destinationFolder


Note the / at the end of the source path, it's important. This solution would add all empty directories, if you don't want them, look at the option --prune-empty-dirs.

With brace expansion you can actually include more filetypes at once, rather than having

--include='*.xls' --include='*.pdf' --include='*.txt'


you can use 

--include='*.'{xls,pdf,txt}
