You can retrieve the particular value of the attribute using the function,

您可以使用函数检索属性的特定值，

QString QDomElement::attribute ( const QString & name, const QString & defValue = QString() ) const

To get all the attributes use,

要得到所有属性，

QDomNamedNodeMap QDomElement::attributes () const

and you have to traverse through the DomNamedNodeMap and get the value of each of the attributes. Hope it helps.

您必须遍历DomNamedNodeMap并获取每个属性的值。希望它可以帮助。

Edit : Try this one.

编辑:试试这个。

With the QDomNamedNodeMap you are having give,

有了QDomNamedNodeMap，

QDomNode QDomNamedNodeMap::item ( int index ) const

which will return a QDomNode for the particular attribute. Then give,

它将返回特定属性的QDomNode。然后给,

QDomAttr QDomNode::toAttr () const

With the QDomAttr obtained give,

用QDomAttr获得give，

QString name () const

which will return the name of the attribute. Hope it helps.

它将返回属性的名称。希望它可以帮助。

How to get first attribute name/value in PySide/PyQt:

如何获得PySide/PyQt中的第一个属性名/值:

if node.hasAttributes():
    nodeAttributes = node.attributes()
    attributeItem = nodeAttributes.item(0) #pulls out first item
    attribute = attributeItem.toAttr()
    attributeName = attr.name()
    attributeValue = attr.value()

This just shows how to get one name/value pair, but it should be easy enough to extend looping with nodeAttributes.length() or something similar.

这只是展示了如何获得一个名称/值对，但是使用nodeAttributes.length()或类似的东西扩展循环应该足够简单。

This is for c++. I Ran into the same problem. You need to convert to QDomAttr. I'm sure API is the same in python.

这是c++。我遇到了同样的问题。您需要转换到QDomAttr。我确信在python中API是一样的。

if( Node.hasAttributes() )
{
    QDomNamedNodeMap map = Node.attributes();
    for( int i = 0 ; i < map.length() ; ++i )
    {
        if(!(map.item(i).isNull()))
        {
            QDomNode debug = map.item(i);
            QDomAttr attr = debug.toAttr();
            if(!attr.isNull())
            {
                cout << attr.value().toStdString();
                cout << attr.name().toStdString();
            }
    }
}
