What kind of update? If it's just text search and replace then I'd use sed

Since this is posted in the I/O and Streams, I would assume that you would want to do it programmatically. If the XML is lying at a remote server, I would try exploring on WebSocket and Streams to see if I can split the parsing. Transferring 500MB of data in one go is definitely not advised.
