詳細描述

An attribute consists of an optionally empty namespaceUri ()， name ()， value (), and an isDefault () attribute.

The raw XML attribute name is returned as qualifiedName ().

QXmlStreamAttribute:: QXmlStreamAttribute ()

Creates an empty attribute.

QXmlStreamAttribute:: QXmlStreamAttribute (const QString & qualifiedName , const QString & value )

Constructs an attribute with qualified name qualifiedName and value value .

QXmlStreamAttribute:: QXmlStreamAttribute (const QString & namespaceUri , const QString & name , const QString & value )

Constructs an attribute in the namespace described with namespaceUri with name and value value .

bool QXmlStreamAttribute:: isDefault () const

返迴 true if the parser added this attribute with a default value following an ATTLIST declaration in the DTD; otherwise returns false .

QStringView QXmlStreamAttribute:: 名稱 () const

Returns the attribute's local name.

QStringView QXmlStreamAttribute:: namespaceUri () const

Returns the attribute's resolved namespaceUri, or an empty string reference if the attribute does not have a defined namespace.

QStringView QXmlStreamAttribute:: prefix () const

Returns the attribute's namespace prefix.

另請參閱 name () 和 qualifiedName ().

QStringView QXmlStreamAttribute:: qualifiedName () const

Returns the attribute's qualified name.

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 qualifiedName(), but the resolved namespaceUri () and the attribute's local name ().

QStringView QXmlStreamAttribute:: value () const

Returns the attribute's value.

[noexcept] bool operator!= (const QXmlStreamAttribute & lhs , const QXmlStreamAttribute & rhs )

比較 lhs 屬性采用 rhs 並返迴 true 若它們不相等；否則返迴 false .

[noexcept] bool operator== (const QXmlStreamAttribute & lhs , const QXmlStreamAttribute & rhs )

比較 lhs 屬性采用 rhs 並返迴 true 若它們相等；否則返迴 false .
