Detailed Description
The TQXmlAttributes class provides XML attributes.
If attributes are reported by TQXmlContentHandler::startElement()
this class is used to pass the attribute values.
Use index() to locate the position of an attribute in the list,
count() to retrieve the number of attributes, and clear() to
remove the attributes. New attributes can be added with append().
Use type() to get an attribute's type and value() to get its
value. The attribute's name is available from localName() or
qName(), and its namespace URI from uri().
See also XML.
Member Function Documentation
TQXmlAttributes::TQXmlAttributes ()
Constructs an empty attribute list.
TQXmlAttributes::~TQXmlAttributes () [virtual]
Destroys the attributes object.
void TQXmlAttributes::append ( const TQString & qName, const TQString & uri, const TQString & localPart, const TQString & value )
Appends a new attribute entry to the list of attributes. The
qualified name of the attribute is qName, the namespace URI is
uri and the local name is localPart. The value of the
attribute is value.
See also qName(), uri(), localName(), and value().
void TQXmlAttributes::clear ()
Clears the list of attributes.
See also append().
int TQXmlAttributes::count () const
Returns the number of attributes in the list. This function is
equivalent to length().
int TQXmlAttributes::index ( const TQString & qName ) const
Looks up the index of an attribute by the qualified name qName.
Returns the index of the attribute or -1 if it wasn't found.
See also the namespace description.
int TQXmlAttributes::index ( const TQString & uri, const TQString & localPart ) const
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Looks up the index of an attribute by a namespace name.
uri specifies the namespace URI, or an empty string if the name
has no namespace URI. localPart specifies the attribute's local
name.
Returns the index of the attribute, or -1 if it wasn't found.
See also the namespace description.
int TQXmlAttributes::length () const
Returns the number of attributes in the list.
See also count().
Example: xml/tagreader-with-features/structureparser.cpp.
TQString TQXmlAttributes::localName ( int index ) const
Looks up an attribute's local name for the attribute at position
index. If no namespace processing is done, the local name is
TQString::null.
See also the namespace description.
TQString TQXmlAttributes::qName ( int index ) const
Looks up an attribute's XML 1.0 qualified name for the attribute
at position index.
See also the namespace description.
Example: xml/tagreader-with-features/structureparser.cpp.
TQString TQXmlAttributes::type ( int index ) const
Looks up an attribute's type for the attribute at position index.
Currently only "CDATA" is returned.
TQString TQXmlAttributes::type ( const TQString & qName ) const
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Looks up an attribute's type for the qualified name qName.
Currently only "CDATA" is returned.
TQString TQXmlAttributes::type ( const TQString & uri, const TQString & localName ) const
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Looks up an attribute's type by namespace name.
uri specifies the namespace URI and localName specifies the
local name. If the name has no namespace URI, use an empty string
for uri.
Currently only "CDATA" is returned.
TQString TQXmlAttributes::uri ( int index ) const
Looks up an attribute's namespace URI for the attribute at
position index. If no namespace processing is done or if the
attribute has no namespace, the namespace URI is TQString::null.
See also the namespace description.
Example: xml/tagreader-with-features/structureparser.cpp.
TQString TQXmlAttributes::value ( int index ) const
Looks up an attribute's value for the attribute at position index.
TQString TQXmlAttributes::value ( const TQString & qName ) const
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Looks up an attribute's value for the qualified name qName.
See also the namespace description.
TQString TQXmlAttributes::value ( const TQString & uri, const TQString & localName ) const
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Looks up an attribute's value by namespace name.
uri specifies the namespace URI, or an empty string if the name
has no namespace URI. localName specifies the attribute's local
name.
See also the namespace description.
