解析嵌套的XML與LXML和Python

Question

我有麻煩解析XML當它在形式：

<Cars> 
    <Car> 
     <Color>Blue</Color> 
     <Make>Ford</Make> 
     <Model>Mustant</Model> 
    </Car> 
    <Car> 
     <Color>Red</Color> 
     <Make>Chevy</Make> 
     <Model>Camaro</Model> 
    </Car> 
</Cars> 

我想通了如何解析1級的孩子是這樣的：

<Car> 
    <Color>Blue</Color> 
    <Make>Chevy</Make> 
    <Model>Camaro</Model> 
</Car> 

有了這樣的代碼：

from lxml import etree 
    a = os.path.join(localPath,file) 
    element = etree.parse(a) 
    cars = element.xpath('//Root/Foo/Bar/Car/node()[text()]') 
    parsedCars = [{field.tag: field.text for field in cars} for action in cars] 
    print parsedCars[0]['Make'] #Chevy 

我如何分析我們的多「車」的標籤是「汽車總動員」的子標籤？

試試這個

from lxml import etree 
    a = os.path.join(localPath,file) 
    element = etree.parse(a) 
    cars = element.xpath('//Root/Foo/Bar/Car') 
    for car in cars: 
     colors = car.xpath('./Color') 
     makes = car.xpath('./Make') 
     models = car.xpath('./Model')
