Examples of weblogic.xml.stream.XMLInputStream

weblogic.xml.stream.XMLInputStream
This is the top level interface for iterating over XML Events in an XML document.
Difference from SAX

An event stream can be thought of encapsulating SAX events. It applies an iterator/pull metaphor to the parser allowing procedural, stream-based, handling of input XML rather than having to write chained event handlers to handle complex XML documents.
Difference from DOM

The pull metaphor allows single-pass, stream-based parsing of the document rather than tree based manipulation.
