About

Streaming refers to a programming model in which XML infosets

• are transmitted and parsed serially:
  • at application runtime,
  • often in real time,
  • and often from dynamic sources
• whose contents are not precisely known beforehand.

Streaming provides high performance (smaller memory footprint, reduced processor requirements).

As you can only see the XML infosets state at one location at a time in the document, you need to know what processing you want to do before reading the XML document.

Streaming models are particularly useful when your application:

• has strict memory limitations (cellphone, …)
• needs to process several requests simultaneously (application server)
