This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY.
This interface allows access to a list of attributes in three different ways:
The list will not contain attributes that were declared
#IMPLIED but not specified in the start tag. It will also not
contain attributes used as Namespace declarations (xmlns*) unless
the http://xml.org/sax/features/namespace-prefixes
feature is set to true (it is false by
default).
Because SAX2 conforms to the original "Namespaces in XML"
recommendation, it normally does not
give namespace declaration attributes a namespace URI.
Some SAX2 parsers may support using an optional feature flag
(http://xml.org/sax/features/xmlns-uris
) to request that
those attributes be given URIs, conforming to a later
backwards-incompatible revision of that recommendation.
(The attribute's "local name" will be the prefix, or the empty
string when defining a default element namespace.)
For portability, handler code should always resolve that conflict,
rather than requiring parsers that can change the setting of that
feature flag.
If the namespace-prefixes feature (see above) is false,
access by qualified name may not be available; if the
http://xml.org/sax/features/namespaces
feature is false, access by Namespace-qualified names
may not be available.
This interface replaces the now-deprecated SAX1 (IAttributeList) interface, which does not contain Namespace support. In addition to Namespace support, it adds the getIndex methods (below).
The order of attributes in the list is unspecified, and will vary from implementation to implementation.
function getLength() : Integer;
Return the number of attributes in the list.Once you know the number of attributes, you can iterate through the list.
function getURI( index : Integer) : SAXString;
Look up an attribute's Namespace URI by index.function getLocalName( index : Integer) : SAXString;
Look up an attribute's local name by index.function getQName( index : Integer) : SAXString;
Look up an attribute's XML 1.0 qualified name by index.function getType( index : Integer) : SAXString;
Look up an attribute's type by index.The attribute type is one of the strings "CDATA", "ID", "IDREF", "IDREFS", "NMTOKEN", "NMTOKENS", "ENTITY", "ENTITIES", or "NOTATION" (always in upper case).
If the parser has not read a declaration for the attribute, or if the parser does not report attribute types, then it must return the value "CDATA" as stated in the XML 1.0 Recommendation (clause 3.3.3, "Attribute-Value Normalization").
For an enumerated attribute that is not a notation, the parser will report the type as "NMTOKEN".
function getType(const uri : SAXString; const localName : SAXString) : SAXString;
Look up an attribute's value by XML 1.0 qualified name.See getValue(Integer) for a description of the possible values.
function getType(const qName : SAXString) : SAXString;
Look up an attribute's type by XML 1.0 qualified name.See getType(Integer) for a description of the possible types.
function getValue( index : Integer) : SAXString;
Look up an attribute's value by index.If the attribute value is a list of tokens (IDREFS, ENTITIES, or NMTOKENS), the tokens will be concatenated into a single string with each token separated by a single space.
function getValue(const uri : SAXString; const localName : SAXString) : SAXString;
Look up an attribute's type by Namespace name.See getType(Integer) for a description of the possible types.
function getValue(const qName : SAXString) : SAXString;
Look up an attribute's value by Namespace name.See getValue(Integer) for a description of the possible values.
function getIndex(const uri : SAXString; const localName : SAXString) : Integer;
Look up the index of an attribute by Namespace name.function getIndex(const qName : SAXString) : Integer;
Look up the index of an attribute by XML 1.0 qualified name.Length
