Frequently Asked Questions

Should I use DOM or SAX parsing for large XML?

For files over 1MB, prefer SAX (event-based) or StAX (pull-based) streaming parsers. DOM parsing loads the entire document into memory — a 5MB XML file can use 50–100MB of RAM as a DOM tree.

How do I handle XML files that are too large for memory?

Use streaming parsers: xml.sax in Python, SAXParser in Java, sax-js in Node.js. These process elements as they're read, using constant memory regardless of file size. Process and discard each element instead of building a full tree.

What performance should I expect parsing 5MB XML?

DOM parsing: 100–500ms. SAX/StAX streaming: 50–200ms. If your parser takes longer than 1 second, check for unnecessary string copying, excessive namespace resolution, or schema validation overhead.
