Detailed Description
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.
New attributes can be added with append().
Member Function Documentation
QXmlStreamAttributes::QXmlStreamAttributes()
A constructor for QXmlStreamAttributes.
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 QString &qualifiedName, const QString &value)
This is an overloaded function.
Appends a new attribute with qualified name qualifiedName and value value.
QStringView 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.
QStringView QXmlStreamAttributes::value(const QString &namespaceUri, QLatin1StringView name) const
This is an overloaded function.
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.
QStringView QXmlStreamAttributes::value(QLatin1StringView namespaceUri, QLatin1StringView name) const
This is an overloaded function.
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.
QStringView QXmlStreamAttributes::value(const QString &qualifiedName) const
This is an overloaded function.
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.
QStringView QXmlStreamAttributes::value(QLatin1StringView qualifiedName) const
This is an overloaded function.
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.
