Detailed Description

The QXmlStreamAttributes class represents a vector of QXmlStreamAttribute.

\inmodule QtCore

Since: 4.3 \reentrant

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

Constructor & Destructor Documentation

◆ QXmlStreamAttributes()

QXmlStreamAttributes::QXmlStreamAttributes ( )

inline

A constructor for QXmlStreamAttributes.

Definition at line 113 of file qxmlstream.h.

Member Function Documentation

◆ append() [1/2]

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.

Definition at line 2655 of file qxmlstream.cpp.

Here is the caller graph for this function:

◆ append() [2/2]

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

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Appends a new attribute with qualified name qualifiedName and value value.

Definition at line 2664 of file qxmlstream.cpp.

Here is the call graph for this function:

◆ hasAttribute() [1/3]

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

inline

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Since: 4.5

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

Definition at line 132 of file qxmlstream.h.

Here is the call graph for this function:

◆ hasAttribute() [2/3]

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

inline

Since: 4.5

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.

Definition at line 122 of file qxmlstream.h.

Here is the call graph for this function:

◆ hasAttribute() [3/3]

bool QXmlStreamAttributes::hasAttribute ( QLatin1String qualifiedName ) const

inline

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Since: 4.5

Definition at line 127 of file qxmlstream.h.

Here is the call graph for this function:

◆ value() [1/5]

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.

Definition at line 2572 of file qxmlstream.cpp.

Here is the caller graph for this function:

◆ value() [2/5]

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

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. 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.

Definition at line 2586 of file qxmlstream.cpp.

Here is the caller graph for this function:

◆ value() [3/5]

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

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

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.

Definition at line 2621 of file qxmlstream.cpp.

Here is the caller graph for this function:

◆ value() [4/5]

QStringView QXmlStreamAttributes::value	(	QLatin1String	namespaceUri,
		QLatin1String	name
	)		const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. 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.

Definition at line 2600 of file qxmlstream.cpp.

Here is the caller graph for this function:

◆ value() [5/5]

QStringView QXmlStreamAttributes::value ( QLatin1String qualifiedName ) const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

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.
