Copy files recursively without keeping directory structure (Linux)

We had to copy many files that were located in a very complex directory structure. The following snippet searches the current directory and its subdirectories for *.xml files & executes the cp command on every file it finds (the braces {} represent the file):

find -type f -iname '*.xml' -exec cp {} /target/dir/for/all/xmls/ \;

The target dir now contains all *.xml files without directories.
