Out of the box, no.

Here's a (lightly tested) script that will list the delta between 2
revision numbers on a branch, assuming that X is an ancestor of Y. I
leave it as an exercise to the reader to uncomment the export commands
and test them.

$ svn log -q -v -r X:Y URL | perl a.pl
    note: X<Y
    note: use 'svn log -q -v'

use strict;

use File::Basename;

my %h;
while (<>) {


    if ( /^ (.) (.*)/ ) {
        my $filename = $2;
        my $action = $1;

        $filename =~ s/ \(from .*:\d+\)$//;

        $h{$filename} = "$action";

        if ( $action !~ /^A|M|D$/ ) {
            warn "Warning! unknown action: '$action' for $filename\n";
            print STDERR ;

print "Delta:\n";
foreach my $filename (sort keys %h) {
    if ( $h{$filename} =~ /^A|M/ ) {
        print "\t$filename\n";
        #my $dir = dirname($filename);
        #$dir =~ s/^$root_dir//;
        #print qq(mkdir -p "$dir\n);
        #print qq(svn export "$file" "$dir"\n);

print "\nDeletions:\n";
foreach my $filename (sort keys %h) {
    if ( $h{$filename} eq 'D' ) {
        print "\t$filename\n";
        #print qq(rm -rf "$filename"\n); ## could be a dir.
