Load Large XML doc into Oracle using Bfilename

My overall goal is to be able to search for specific data in this xlm document probably using XLMQUERY.  Using Oracle 12c, 64bit, windows 2012r2 server, trying to load a 50meg XLM document and verify data correctly loaded.

Using,

CREATE XML_TABLE
(
  XML_DATA  XMLTYPE
);

INSERT INTO xml_table
  VALUES (XMLType(bfilename('XML_DIR', '50Meg_doc.xml'),
                  nls_charset_id('AL32UTF8')));
commit;

to check data,

select XMLQuery('//Navaid/NavaidID' PASSING XML_DATA  RETURNING CONTENT)
from xml_table;

nothing returns.

Sample of data.
