Подробное описание

Класс QXmlStreamAttributes представляет вектор, состоящий из QXmlStreamAttribute.

Attributes are returned by a QXmlStreamReader in attributes() when the reader reports a start element. The class can also be used with a QXmlStreamWriter as an argument to writeAttributes().

The convenience function value() loops over the vector and returns an attribute value for a given namespaceUri and an attribute's name.

Новые атрибуты могут быть добавлены с помощью append().

Описание функций-членов

void QXmlStreamAttributes::append ( const QString & namespaceUri, const QString & name, const QString & value )

Appends a new attribute with name in the namespace described with namespaceUri, and value value. The namespaceUri can be empty.

void QXmlStreamAttributes::append ( const QXmlStreamAttribute & attribute )

Appends the given attribute to the end of the vector.

See also QVector::append().

void QXmlStreamAttributes::append ( const QString & qualifiedName, const QString & value )

Это перегруженная функция.

Appends a new attribute with qualified name qualifiedName and value value.

bool QXmlStreamAttributes::hasAttribute ( const QString & qualifiedName ) const

Returns true if this QXmlStreamAttributes has an attribute whose qualified name is qualifiedName; otherwise returns false.

Note that this is not namespace aware. For instance, if this QXmlStreamAttributes contains an attribute whose lexical name is "xlink:href" this doesn't tell that an attribute named href in the XLink namespace is present, since the xlink prefix can be bound to any namespace. Use the overload that takes a namespace URI and a local name as parameter, for namespace aware code.

Эта функция была введена в Qt 4.5.

bool QXmlStreamAttributes::hasAttribute ( const QLatin1String & qualifiedName ) const

Это перегруженная функция.

Эта функция была введена в Qt 4.5.

bool QXmlStreamAttributes::hasAttribute ( const QString & namespaceUri, const QString & name ) const

Это перегруженная функция.

Returns true if this QXmlStreamAttributes has an attribute whose namespace URI and name correspond to namespaceUri and name; otherwise returns false.

QStringRef QXmlStreamAttributes::value ( const QString & namespaceUri, const QString & name ) const

Returns the value of the attribute name in the namespace described with namespaceUri, or an empty string reference if the attribute is not defined. The namespaceUri can be empty.

QStringRef QXmlStreamAttributes::value ( const QString & namespaceUri, const QLatin1String & name ) const

Это перегруженная функция.

Returns the value of the attribute name in the namespace described with namespaceUri, or an empty string reference if the attribute is not defined. The namespaceUri can be empty.

QStringRef QXmlStreamAttributes::value ( const QLatin1String & namespaceUri, const QLatin1String & name ) const

Это перегруженная функция.

Returns the value of the attribute name in the namespace described with namespaceUri, or an empty string reference if the attribute is not defined. The namespaceUri can be empty.

QStringRef QXmlStreamAttributes::value ( const QString & qualifiedName ) const

Это перегруженная функция.

Returns the value of the attribute with qualified name qualifiedName , or an empty string reference if the attribute is not defined. A qualified name is the raw name of an attribute in the XML data. It consists of the namespace prefix, followed by colon, followed by the attribute's local name. Since the namespace prefix is not unique (the same prefix can point to different namespaces and different prefixes can point to the same namespace), you shouldn't use qualified names, but a resolved namespaceUri and the attribute's local name.
