Have a look at:

Bruce decides who gets to have svn access. In the mean time, sending in
a diff is a good way to show how you work.

It depends how many files you've changed. If it's just the one then I
usually just put them next to each other by adding .orig to the end of
the original then

diff -u path/to/the/file.xml{.orig,} > ~/output.diff

man diff is a good place to start.

Yes that will work fine if you have altered several files. However, the
svn folders contain lots of files and diff will need to examine them
all which may take some time and add lots of spurious changes that may
need to be removed by hand.
Another option is to use svn. It knows what the files should look like.
Try:
svn diff > ~/mycontribution.diff
