BOGONS_EMPTY_FEATURE

A value of true indicates that the parser will give unknown elements a content model of EMPTY; a value of false, a content model of ANY.

Declaration

public const string BOGONS_EMPTY_FEATURE = "http://www.ccil.org/~cowan/tagsoup/features/bogons-empty"

Field Value

CDATA_ELEMENTS_FEATURE

A value of "true" indicates that the parser will treat CDATA elements specially. Normally true, since the input is by default HTML.

IGNORABLE_WHITESPACE_FEATURE

A value of "true" indicates that the parser will transmit whitespace in element-only content via the SAX ignorableWhitespace callback. Normally this is not done, because HTML is an SGML application and SGML suppresses such whitespace.

Declaration

public const string IGNORABLE_WHITESPACE_FEATURE = "http://www.ccil.org/~cowan/tagsoup/features/ignorable-whitespace"

Field Value

Type	Description
System.String

Field Value

Type	Description
System.String

IS_STANDALONE_FEATURE

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. (It's always false.)

Declaration

public const string IS_STANDALONE_FEATURE = "http://xml.org/sax/features/is-standalone"

Field Value

LEXICAL_HANDLER_PROPERTY

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 ILexicalHandler

Declaration

RESOLVE_DTD_URIS_FEATURE

STRING_INTERNING_FEATURE

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 J2N.Text.StringExtensions.Intern(System.String). This supports fast testing of equality/inequality against string constants, rather than forcing slower calls to System.String.Equals(System.Object). (We always intern.)
