Java XML Parser for huge files

Question

I need a xml parser to parse a file that is approximately 1.8 gb.
So the parser should not load all the file to memory.

Any suggestions?

Answer 1

Aside the recommended SAX parsing, you could use the StAX API (kind of a SAX evolution), included in the JDK (package javax.xml.stream ).

• StAX Project Home: http://stax.codehaus.org/Home
• Brief introduction: http://www.xml.com/pub/a/2003/09/17/stax.html
• Javadoc: https://docs.oracle.com/javase/8/docs/api/javax/xml/stream/package-summary.html

Answer 2

Use a SAX based parser that presents you with the contents of the document in a stream of events.
