Answer 1

You can convert this XML to JSON format and save it in a NoSQL database like MongoDB.

UPDATE : If you need to save it into a SQL Database I think you would need to use JAXB or XMLBeans to convert to java objects and then use JDBC or JPA to save it into the DB.

Bonus idea (Tristan) : In second solution, you may also chose for which portion of XML you actually need precise data in SQL DB and for the other portion you would store it in a CLOB field.

Answer 2

Best way is to stick it in your SQL database. You can easily run it through SQLizer, which will convert XML to SQL and give you table definitions and multiple INSERT statements.

This will also let your choose specific portions of the XML file to convert.
