QXmlAttributes 类提供 XML 属性。

If attributes are reported by QXmlContentHandler.startElement () this class is used to pass the attribute values.

使用 index () to locate the position of an attribute in the list, count () to retrieve the number of attributes, and clear () 到 remove the attributes. New attributes can be added with append ()。使用 type () to get an attribute's type and value () to get its value. The attribute's name is available from localName () 或 qName (), and its namespace URI from uri ().

方法文档编制

QXmlAttributes.init ( self )

Constructs an empty attribute list.

QXmlAttributes.init ( self , QXmlAttributes )

QXmlAttributes.append ( self , QString qName , QString uri , QString localPart , QString 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 .

另请参阅 qName (), uri (), localName ()，和 value ().

QXmlAttributes.clear ( self )

Clears the list of attributes.

另请参阅 append ().

int QXmlAttributes.count ( self )

Returns the number of attributes in the list. This function is equivalent to length ().

int QXmlAttributes.index ( self , QString qName )

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.

int QXmlAttributes.index ( self , QString uri , QString localPart )

这是重载函数。

int QXmlAttributes.length ( self )

Returns the number of attributes in the list.

另请参阅 count ().

QString QXmlAttributes.localName ( self , int index )

Looks up an attribute's local name for the attribute at position index . If no namespace processing is done, the local name is an empty string.

另请参阅 Namespace Support via 特征 .

QString QXmlAttributes.qName ( self , int index )

Looks up an attribute's XML 1.0 qualified name for the attribute 在位置 index .

另请参阅 Namespace Support via 特征 .

QString QXmlAttributes.type ( self , int index )

Looks up an attribute's type for the attribute at position index .

Currently only "CDATA" is returned.

QString QXmlAttributes.type ( self , QString qName )

这是重载函数。

Looks up an attribute's type for the qualified name qName .

Currently only "CDATA" is returned.

QString QXmlAttributes.type ( self , QString uri , QString localName )

这是重载函数。

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.

QString QXmlAttributes.uri ( self , int index )

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 an empty string.

另请参阅 Namespace Support via 特征 .

QString QXmlAttributes.value ( self , int index )

Returns an attribute's value for the attribute at position index . The index must be a valid position (i.e., 0 <= index < count ()).

QString QXmlAttributes.value ( self , QString qName )

这是重载函数。

Returns an attribute's value for the qualified name qName , or an empty string if no attribute exists for the name given.

另请参阅 Namespace Support via 特征 .

QString QXmlAttributes.value ( self , QString uri , QString localName )

这是重载函数。

Returns an attribute's value for the qualified name qName , or an empty string if no attribute exists for the name given.
