Python navigate lxml.objectify properties

Question

I am having problems accessing a list of ObjectifiedElement and their properties. I have a package that just gives me a list of ObjectifiedElement type I have tried to convert the first element in the list by using lxml.objectify.dump

The error is unrelated so I will remove here. This is the code I have used to output the object below

print ("Images: ")
print (lxml.objectify.dump(self.product.images[0]))

And this is the output;

{http://webservices.amazon.com/AWSECommerceService/2013-08-01}ImageSet = None [ObjectifiedElement]

    {http://webservices.amazon.com/AWSECommerceService/2013-08-01}SwatchImage = None [ObjectifiedElement]

I am trying to get the property of URL in each instance.

Update

I have managed to access the object properties in a loop. Here is the code;

for e in self.product.images[0].getchildren():
    print("Tag: L1: "+e.tag)
    for v in e.getchildren():
        print("Tag: L2: "+v.tag+" : "+v.text)

And I got this;

Tag: L1: {http://webservices.amazon.com/AWSECommerceService/2013-08-01}SwatchImage
Tag: L2: {http://webservices.amazon.com/AWSECommerceService/2013-08-01}URL : https://images-eu.ssl-images-amazon.com/images/I/41F%2BAxAz4BL._SL30_.jpg

Tag: L2: {http://webservices.amazon.com/AWSECommerceService/2013-08-01}Width : 2560

Now I am trying to access each of the properties and get the HiResImage URL without using the loop.

Answer 1

Have you tried print self.product.images[0].HiResImage.URL ?

EDIT:

I simulated a minimized object of your dump to have only the element you want to access

a = '''<f:ImageSet xmlns:f="http://webservices.amazon.com/AWSECommerceService/2013-08-01" Category = 'variant'>
    <f:HiResImage xmlns:f="http://webservices.amazon.com/AWSECommerceService/2013-08-01">
        <f:URL xmlns:f="http://webservices.amazon.com/AWSECommerceService/2013-08-01">https://images-eu.ssl-images-amazon.com/images/I/71whgyNdlVL.jpg</f:URL>
    </f:HiResImage>
</f:ImageSet>'''

o = objectify.fromstring(a)
print objectify.dump(o)

Giving as a result:

{http://webservices.amazon.com/AWSECommerceService/2013-08-01}ImageSet = None [ObjectifiedElement]
  * Category = 'variant'
    {http://webservices.amazon.com/AWSECommerceService/2013-08-01}HiResImage = None [ObjectifiedElement]
        {http://webservices.amazon.com/AWSECommerceService/2013-08-01}URL = 'https://images-eu.ssl-images-amazon.com/images/I/71whgyNdlVL.jpg' [StringElement]

Which is similar to what you posted. Then I can access to the URL like this:

>>> print o.HiResImage.URL
https://images-eu.ssl-images-amazon.com/images/I/71whgyNdlVL.jpg
