find . ! -type d -print|xargs grep xyz /dev/null

Specifying /dev/null as the first file argument to grep deals with the
case where xargs passes only one argument to grep.  That would cause
grep to not display the name of the file if it found the search string
in the file.  Passing /dev/null to each invocation of grep guarantees
that grep will have at least two argument which will cause it to always
display file names.
