Is there a way to have a sparse checkout of an SVN repo with deep nested directory structure.

I'm doing this using a listing of all the files in the repo and filtering for just *.xml:

svn list --recursive "http://myRepo.com/trunk" > allFiles.txt

I'm trying to do the following:

svn checkout "http://myRepo.com/trunk" --depth empty "myRepo"
svn update --set-depth empty project1/dirs/moreDirs/evenMore/file.xml

I tried this but got an error saying it was skipping updating that file.

If I manually do the following I can get the file in my checkout (I want a --set-depth empty that gets the parent directories for a nested SVN path).

svn update --set-depth empty project1
svn update --set-depth empty project1/dirs/moreDirs
svn update --set-depth empty project1/dirs/moreDirs/evenMore
svn update --set-depth empty project1/dirs/moreDirs/evenMore/file.xml

svn status -v project1/dirs/moreDirs/evenMore/file.xml
# prints svn file information

EDIT

I have 2 workarounds right now neither ideal

1. piece-meal svn update --set-depth empty

I wrote a bash function that takes the file path that I'm looking for a executes svn update --set-depth empty on it. For example for project1/dirs/moreDirs/evenMore/file.xml it would call:

svn update --set-depth empty updateproject1 updateproject1/dirs updateproject1/dirs/moreDirs updateproject1/dirs/moreDirs/evenMore updateproject1/dirs/moreDirs/evenMore/file.xml

It works but seems like it's pretty slow (maybe I can batch the calls for multiple files into one svn update call). I can't make multiple svn update calls for separate files in parallel because svn locks the repo.

Here's the full script:

function getContentFile() 
 true
 done
 svn update --set-depth empty $SVN_UPDATE_ARG
 fi

# export function to use in xargs
export -f getContentFile

cat "$SVN_FILE_LISTING_CACHE" | egrep '.xml$' | xargs -P 1 -n 1 -I bash -e -c 'getContentFile "$@"' _ 

2. svn cat to get files

I can also just create the path for the folder structure and svn cat the file and I can do it on multiple files at the same time, but this suffers from not being connected to svn (e.g. I can't commit it back easily or update the file from svn without walking and matching the path), it's not a real svn checkout.

function getAllContentFiles() 
 egrep $FILE_REGEX 

function getContentFile() 


 CONTENT_FILE="$1"
 SVN_FILE="$SVN_REMOTE$CONTENT_FILE"
 LOCAL_CONTENT_FILE="$SVN_CHECKOUT/$CONTENT_FILE"
 LOCAL_CONTENT_FILE_DIR=$(dirname $LOCAL_CONTENT_FILE)

 SVN_UPDATE_ARG="$CONTENT_FILE"
 PARENT_DIR="$(dirname $CONTENT_FILE)"
 mkdir -p "$PARENT_DIR"

 if [ ! -e "$LOCAL_CONTENT_FILE" ]; then
 pushd "$SVN_CHECKOUT"
 svn cat "$SVN_FILE" > "$LOCAL_CONTENT_FILE"
 fi

Since Subversion 1.7.0 update has accepted a --parents option that does what you want.

So you can do the following for example:

$ svn co --depth empty https://svn.apache.org/repos/asf/subversion svn-sparse
 U svn-sparse
Checked out revision 1544721.

$ svn up --parents trunk/subversion/libsvn_ra_svn/protocol
