RECURSING INTO SUB‐DOCUMENTS

       Libbson  provides  convenient sub‐iterators to dive down into a sub‐document or sub‐array.
       Below is an example that will dive into a sub‐document named "foo" and  print  it's  field
       names.

FINDING FIELDS USING DOT NOTATION

       Using  the  bson_iter_recurse(3)  function exemplified above, bson_iter_find_descendant(3)
       can find a field for you using the MongoDB style path notation such as "foo.bar.0.baz".

       Let's create a document like {"foo": {"bar": [{"baz: 1}]}} and locate the baz field.

VALIDATING A BSON DOCUMENT

       If all you  want  to  do  is  validate  that  a  BSON  document  is  valid,  you  can  use
       bson_validate(3) \&.

       See the bson_validate(3) documentation for more information and examples.
