git-add dir recursively but obeying gitignore

im using git with java so i have deeply nested directories. to add a pattern to git recursively开发者_高级运维, I am using:

find . -iname "*.xml" | xargs git add

which detects ignored directories like 'bin' and aborts (because the shell expands my wildcard, not git)

what is a better way?

git ls-files --exclude-standard -o | grep '\.xml$'

i hadn't found git add -A which does what i need
