Attributes are returned by a [QXmlStreamReader](qxmlstreamreader.html) in [attributes()](qxmlstreamreader.html#attributes) when the reader reports a [start element](qxmlstreamreader.html#TokenType-enum). The class can also be used with a [QXmlStreamWriter](qxmlstreamwriter.html) as an argument to [writeAttributes()](qxmlstreamwriter.html#writeAttributes). The convenience function [value](qxmlstreamattributes.html#value)() loops over the vector and returns an attribute value for a given namespaceUri and an attribute's name. 新的屬性可以被添加[append](qxmlstreamattributes.html#append)（）。 * * * ## Method Documentation ``` QXmlStreamAttributes.__init__ (self) ``` ``` QXmlStreamAttributes.__init__ (self, QXmlStreamAttributes) ``` ``` QXmlStreamAttributes.append (self, QString?namespaceUri, QString?name, QString?value) ``` 附加一個新的屬性_name_在與所描述的命名空間_namespaceUri_和值_value_。該_namespaceUri_可以為空。 ``` QXmlStreamAttributes.append (self, QString?qualifiedName, QString?value) ``` 添加給定的_attribute_向矢量的末端。 **See also** [QVector.append](index.htm#append)（）。 ``` QXmlStreamAttributes.append (self, QXmlStreamAttribute?attribute) ``` 這是一個重載函數。與追加限定名的新屬性_qualifiedName_和值_value_。 ``` QXmlStreamAttribute QXmlStreamAttributes.at (self, int?i) ``` [ ``` QXmlStreamAttributes.clear (self) ``` ``` bool QXmlStreamAttributes.contains (self, QXmlStreamAttribute?value) ``` ``` int QXmlStreamAttributes.count (self, QXmlStreamAttribute?value) ``` ``` int QXmlStreamAttributes.count (self) ``` ``` sip.voidptr QXmlStreamAttributes.data (self) ``` ``` QXmlStreamAttributes.fill (self, QXmlStreamAttribute?value, int?size?=?-1) ``` ](qxmlstreamattribute.html) ``` QXmlStreamAttribute QXmlStreamAttributes.first (self) ``` [ ``` bool QXmlStreamAttributes.hasAttribute (self, QString?qualifiedName) ``` ](qxmlstreamattribute.html) [返回True如果](qxmlstreamattribute.html)[QXmlStreamAttributes](qxmlstreamattributes.html)有一個屬性的限定名是_qualifiedName_否則返回False 。請注意，這不是名稱空間感知。舉例來說，如果此[QXmlStreamAttributes](qxmlstreamattributes.html)包含一個屬性，它的詞匯叫“ XLINK ： HREF ”這不告訴一個名為屬性`href`在XLink的命名空間不存在，因為`xlink`前綴可以綁定到任何命名空間。使用采用命名空間URI和本地名稱作為參數，名稱空間感知的代碼超載。此功能被引入Qt的4.5 。 ``` bool QXmlStreamAttributes.hasAttribute (self, QString?namespaceUri, QString?name) ``` 這是一個重載函數。此功能被引入Qt的4.5 。 ``` int QXmlStreamAttributes.indexOf (self, QXmlStreamAttribute?value, int?from?=?0) ``` ``` QXmlStreamAttributes.insert (self, int?i, QXmlStreamAttribute?value) ``` ``` bool QXmlStreamAttributes.isEmpty (self) ``` ``` QXmlStreamAttribute QXmlStreamAttributes.last (self) ``` [ ``` int QXmlStreamAttributes.lastIndexOf (self, QXmlStreamAttribute?value, int?from?=?-1) ``` ``` QXmlStreamAttributes.prepend (self, QXmlStreamAttribute?value) ``` ``` QXmlStreamAttributes.remove (self, int?i) ``` ``` QXmlStreamAttributes.remove (self, int?i, int?count) ``` ``` QXmlStreamAttributes.replace (self, int?i, QXmlStreamAttribute?value) ``` ``` int QXmlStreamAttributes.size (self) ``` ``` QStringRef QXmlStreamAttributes.value (self, QString?namespaceUri, QString?name) ``` 返回屬性的值_name_在與所描述的命名空間_namespaceUri_，或一個空字符串引用，如果該屬性沒有定義。該_namespaceUri_可以為空。 ``` QStringRef QXmlStreamAttributes.value (self, QString?qualifiedName) ``` 這是一個重載函數。返回屬性的值_name_在與所描述的命名空間_namespaceUri_，或一個空字符串引用，如果該屬性沒有定義。該_namespaceUri_可以為空。 ``` int QXmlStreamAttributes.__contains__ (self, QXmlStreamAttribute?value) ``` ``` QXmlStreamAttributes.__delitem__ (self, int?i) ``` ``` QXmlStreamAttributes.__delitem__ (self, slice?slice) ``` ``` bool QXmlStreamAttributes.__eq__ (self, QXmlStreamAttributes?other) ``` ](qxmlstreamattribute.html) ``` QXmlStreamAttribute QXmlStreamAttributes.__getitem__ (self, int?i) ``` [](qxmlstreamattribute.html) ``` QXmlStreamAttributes QXmlStreamAttributes.__getitem__ (self, slice?slice) ``` [](qxmlstreamattributes.html) ``` QXmlStreamAttributes QXmlStreamAttributes.__iadd__ (self, QXmlStreamAttributes?other) ``` [](qxmlstreamattributes.html) ``` QXmlStreamAttributes QXmlStreamAttributes.__iadd__ (self, QXmlStreamAttribute?value) ``` [ ``` QXmlStreamAttributes.__len__ (self) ``` ``` bool QXmlStreamAttributes.__ne__ (self, QXmlStreamAttributes?other) ``` ``` QXmlStreamAttributes.__setitem__ (self, int?i, QXmlStreamAttribute?value) ``` ``` QXmlStreamAttributes.__setitem__ (self, slice?slice, QXmlStreamAttributes?list) ``` ](qxmlstreamattributes.html)
