Appendix B. SAX 2.0 Features and Properties

This appendix details the SAX 2.0 standard features and properties. Although a vendor’s parsing software can add additional features and properties for vendor-specific functionality, this list represents the core set of functionality that any SAX 2.0-compliant parser implementation should support.

Core Features

The core set of features supported by SAX 2.0 XMLReader implementations is listed here. These features can be set through setFeature( ) , and the value of a feature can be obtained through getFeature( ) . Any feature can be read-only, or read and write; features also may be modifiable only when parsing is occurring, or only when parsing is not occurring.

Namespace Processing

This feature instructs a parser to perform namespace processing, which will cause namespace prefixes, namespace URIs, and element local names to be available through the SAX namespace callbacks (startPrefixMapping( ) and endPrefixMapping( ), as well as certain parameters supplied to startElement( ) and endElement( )). When this feature is true, this processing will occur. When false, namespace processing will not occur (this implies that the namespace prefix reporting feature is on).

Access: Read-only when parsing; read/write when not parsing

Namespace Prefix Reporting

This feature instructs a parser to report the attributes used in namespace declarations, such as the xmlns:[namespace prefix] attributes. When this feature ...
