New and improved and simplified version. Uses 'svn log --diff' to get the
files that changed.
Again, only lightly tested. (The previous script assumed that the order of the
xml attributes didn't change and it did. Ooops.)
I used perl instead of sed due to sed version silliness in regards to tabs; so
feel free to the perl equivalent sed commands to remove the trailing "\t
(revision 12345)" from the "svn log --diff ... | grep '^+++' " output.
Remove the two echo commands to actually run the mkdir/export commands.
Edge case: I didn't test how 'svn log --diff' handles deleted files.
#!/bin/bash
REV=$1
SVNREPO=$2
svn log --diff -r $REV "$SVNREPO" | grep '^+++' | perl -pe 's/^\+\+\+ //;
s/\t.*$//' | while read i
do
D=./`dirname "$i"`
echo mkdir -p "$D"
echo svn export --force "$SVNREPO/$i@$REV" "$D/"
done

The script just drops to the shell with exit code 0. My perl knowledge is very
limited, but to debug I executed this
$ echo "action=\"A\">/trunk/text.txt</path>" | perl -ne 'chomp; $a=1 if /^
action="[AD]"/; print "$1\n" if ( $a && /^ kind="file">(.*)<\/path>/ ); $a=0 if
/<\/path>/;'
I assume that is supposed to do something but for me it just drops to the shell
with exit code 0.
