Standard Features Feature ID Access Default Description external-general-entities read/writeunspecified Reports whether this parser processes external general entities; always true if validating. external-parameter-entities read/writeunspecified Reports whether this parser processes external parameter entities; always true if validating. is-standalone (parsing) read-only, (not parsing) none not applicable May be examined only during a parse, after the startDocument() callback has been completed; read-only. The value is true if the document specified standalone="yes" in its XML declaration, and otherwise is false. lexical-handler/parameter-entities read/writeunspecified A value of "true" indicates that the LexicalHandler will report the beginning and end of parameter entities. namespaces read/write true A value of "true" indicates namespace URIs and unprefixed local names for element and attribute names will be available. namespace-prefixes read/write false A value of "true" indicates that XML qualified names (with prefixes) and attributes (including xmlns* attributes) will be available. resolve-dtd-uris read/writetrue A value of "true" indicates that system IDs in declarations will be absolutized (relative to their base URIs) before reporting. (That is the default behavior for all SAX2 XML parsers.) A value of "false" indicates those IDs will not be absolutized; parsers will provide the base URI from Locator.getSystemId(). This applies to system IDs passed in
It does not apply to EntityResolver.resolveEntity(), which is not used to report declarations, or to LexicalHandler.startDTD(), which already provides the non-absolutized URI. string-interning read/writeunspecified Has a value of "true" if all XML names (for elements, prefixes, attributes, entities, notations, and local names), as well as Namespace URIs, will have been interned using java.lang.String.intern. This supports fast testing of equality/inequality against string constants, rather than forcing slower calls to String.equals(). unicode-normalization-checking read/writefalse Controls whether the parser reports Unicode normalization errors as described in section 2.13 and Appendix B of the XML 1.1 Recommendation. If true, Unicode normalization errors are reported using the ErrorHandler.error() callback. Such errors are not fatal in themselves (though, obviously, other Unicode-related encoding errors may be). use-attributes2 read-only not applicable Returns "true" if the Attributes objects passed by this parser in ContentHandler.startElement() implement the org.xml.sax.ext.Attributes2 interface. That interface exposes additional DTD-related information, such as whether the attribute was specified in the source text rather than defaulted. use-locator2 read-only not applicable Returns "true" if the Locator objects passed by this parser in ContentHandler.setDocumentLocator() implement the org.xml.sax.ext.Locator2 interface. That interface exposes additional entity information, such as the character encoding and XML version used. use-entity-resolver2 read/writetrue Returns "true" if, when setEntityResolver is given an object implementing the org.xml.sax.ext.EntityResolver2 interface, those new methods will be used. Returns "false" to indicate that those methods will not be used. validation read/writeunspecified Controls whether the parser is reporting all validity errors; if true, all external entities will be read. xmlns-uris read/writefalse Controls whether, when the namespace-prefixes feature is set, the parser treats namespace declaration attributes as being in the http://www.w3.org/2000/xmlns/ namespace. By default, SAX2 conforms to the original "Namespaces in XML" Recommendation, which explicitly states that such attributes are not in any namespace. Setting this optional flag to "true" makes the SAX2 events conform to a later backwards-incompatible revision of that recommendation, placing those attributes in a namespace. xml-1.1 read-only not applicable Returns "true" if the parser supports both XML 1.1 and XML 1.0. Returns "false" if the parser supports only XML 1.0.
Standard Property IDs Property ID Description declaration-handler Used to see most DTD declarations except those treated as lexical ("document element name is ...") or which are mandatory for all SAX parsers (DTDHandler). The Object must implement org.xml.sax.ext.DeclHandler. document-xml-version May be examined only during a parse, after the startDocument() callback has been completed; read-only. This property is a literal string describing the actual XML version of the document, such as "1.0" or "1.1". dom-node For "DOM Walker" style parsers, which ignore their parser.parse() parameters, this is used to specify the DOM (sub)tree being walked by the parser. The Object must implement the org.w3c.dom.Node interface. lexical-handler Used to see some syntax events that are essential in some applications: comments, CDATA delimiters, selected general entity inclusions, and the start and end of the DTD (and declaration of document element name). The Object must implement org.xml.sax.ext.LexicalHandler. xml-string Readable only during a parser callback, this exposes a TBS chunk of characters responsible for the current event.
