Interface Summary : IBufferedAttributes2
SAX2 extension to augment the per-attribute information
provided though IBufferedAttributes.
If an implementation supports this extension, the attributes
provided in IBufferedContentHandler.startElement
will implement this interface,
and the http://xml.org/sax/features/use-attributes2
feature flag will have the value true.
This module, both source code and documentation, is in the
Public Domain, and comes with NO WARRANTY.
XMLReader implementations are not required to support this
information, and it is not part of core-only SAX2 distributions.
Note that if an attribute was defaulted (not isSpecified())
it will of necessity also have been declared (isDeclared())
in the DTD.
Similarly if an attribute's type is anything except CDATA, then it
must have been declared.
Since : SAX 2.0 (extensions 1.1 alpha)
Methods
function isDeclared( index : Integer) : Boolean;
Returns false unless the attribute was declared in the DTD.
This helps distinguish two kinds of attributes that SAX reports
as CDATA: ones that were declared (and hence are usually valid),
and those that were not (and which are never valid).
Parameter : index The attribute index (zero-based).
Result : true if the attribute was declared in the DTD,
false otherwise.
Exception : Exception When the
supplied index does not identify an attribute.
Top
function isDeclared( qName : PSAXChar; qNameLength : Integer) : Boolean;
Returns false unless the attribute was declared in the DTD.
This helps distinguish two kinds of attributes that SAX reports
as CDATA: ones that were declared (and hence are usually valid),
and those that were not (and which are never valid).
Parameter : qName The XML 1.0 qualified name.
Parameter : qNameLength The length of the uri buffer
The value may be -1 which indicates that the buffer is
null-terminated. If the value is 0 then the buffer may be nil.
Result : true if the attribute was declared in the DTD,
false otherwise.
Exception : ESAXIllegalArgumentException When the
supplied name does not identify an attribute.
Top
function isDeclared( uri : PSAXChar; uriLength : Integer; localName : PSAXChar; localNameLength : Integer) : Boolean;
Returns false unless the attribute was declared in the DTD.
This helps distinguish two kinds of attributes that SAX reports
as CDATA: ones that were declared (and hence are usually valid),
and those that were not (and which are never valid).
Remember that since DTDs do not "understand" namespaces, the
namespace URI associated with an attribute may not have come from
the DTD. The declaration will have applied to the attribute's
qName.
Parameter : uri The Namespace URI, or the empty string if
the name has no Namespace URI.
Parameter : uriLength The length of the uri buffer
The value may be -1 which indicates that the buffer is
null-terminated. If the value is 0 then the buffer may be nil.
Parameter : localName The attribute's local name.
Parameter : localNameLength The length of the localName buffer
The value may be -1 which indicates that the buffer is
null-terminated. If the value is 0 then the buffer may be nil.
Result : true if the attribute was declared in the DTD,
false otherwise.
Exception : ESAXIllegalArgumentException When the
supplied names do not identify an attribute.
Top
function isSpecified( index : Integer) : Boolean;
Returns true unless the attribute value was provided
by DTD defaulting.
Parameter : index The attribute index (zero-based).
Result : true if the value was found in the XML text,
false if the value was provided by DTD defaulting.
Exception : ESAXIllegalArgumentException When the
supplied index does not identify an attribute.
Top
function isSpecified( uri : PSAXChar; uriLength : Integer; localName : PSAXChar; localNameLength : Integer) : Boolean;
Returns true unless the attribute value was provided
by DTD defaulting.
Remember that since DTDs do not "understand" namespaces, the
namespace URI associated with an attribute may not have come from
the DTD. The declaration will have applied to the attribute's
qName.
Parameter : uri The Namespace URI, or the empty string if
the name has no Namespace URI.
Parameter : uriLength The length of the uri buffer
The value may be -1 which indicates that the buffer is
null-terminated. If the value is 0 then the buffer may be nil.
Parameter : localName The attribute's local name.
Parameter : localNameLength The length of the localName buffer
The value may be -1 which indicates that the buffer is
null-terminated. If the value is 0 then the buffer may be nil.
Result : true if the value was found in the XML text,
false if the value was provided by DTD defaulting.
Exception : ESAXIllegalArgumentException When the
supplied names do not identify an attribute.
Top
function isSpecified( qName : PSAXChar; qNameLength : Integer) : Boolean;
Returns true unless the attribute value was provided
by DTD defaulting.
Parameter : qName The XML 1.0 qualified name.
Parameter : qNameLength The length of the qName buffer
The value may be -1 which indicates that the buffer is
null-terminated. If the value is 0 then the buffer may be nil.
Result : true if the value was found in the XML text,
false if the value was provided by DTD defaulting.
Exception : ESAXIllegalArgumentException When the
supplied name does not identify an attribute.
