Simple CLI tool for pulling subsets of photos out of KPhotoAlbum, by scanning the index.xml directly. Base example:

kpa-grep --tag office --since "last month" | tar cf office-pics.tar --files-from=-

finds the last month's files with the office keyword and puts them in a tar file; it uses the default kphotoalbum index file, and outputs full pathnames so tar can just find them.

Additional args:

• --print0: NUL instead of newline, for xargs -0
• --relative: paths relative to the index file (ie. don't normalize them)
• --index=PATH: explicitly specify the index file
• --json, --xml: output whole records (no surrounding document)
