## Detailed Description
The QXmlStreamAttributes class represents a vector of [QXmlStreamAttribute](qxmlstreamattribute.html).
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.
新的属性可以被添加[append](qxmlstreamattributes.html#append)（ ） 。

## Method Documentation
```
QXmlStreamAttributes.__init__ (self)
```
```
QXmlStreamAttributes.__init__ (self, QXmlStreamAttributes)
```
```
QXmlStreamAttributes.append (self, QString namespaceUri, QString name, QString value)
```
附加一个新的属性_name_在与所描述的命名空间_namespaceUri_和值_value_。该_namespaceUri_可以为空。
```
QXmlStreamAttributes.append (self, QString qualifiedName, QString value)
```
添加给定的_attribute_向矢量的末端。
**See also** [QVector.append](index.htm#append)（ ） 。
```
QXmlStreamAttributes.append (self, QXmlStreamAttribute attribute)
```
这是一个重载函数。
与追加限定名的新属性_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)有一个属性的限定名是_qualifiedName_否则返回False 。
请注意，这不是名称空间感知。举例来说，如果此[QXmlStreamAttributes](qxmlstreamattributes.html)包含一个属性，它的词汇叫“ XLINK ： HREF ”这不告诉一个名为属性`href`在XLink的命名空间不存在，因为`xlink`前缀可以绑定到任何命名空间。使用采用命名空间URI和本地名称作为参数，名称空间感知的代码超载。
此功能被引入Qt的4.5 。
```
bool QXmlStreamAttributes.hasAttribute (self, QString namespaceUri, QString name)
```
这是一个重载函数。
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)
```
返回属性的值_name_在与所描述的命名空间_namespaceUri_，或一个空字符串引用，如果该属性没有定义。该_namespaceUri_可以为空。
```
QStringRef QXmlStreamAttributes.value (self, QString qualifiedName)
```
这是一个重载函数。
返回属性的值_name_在与所描述的命名空间_namespaceUri_，或一个空字符串引用，如果该属性没有定义。该_namespaceUri_可以为空。
```
