Python'da iç içe XML'yi elementtree ile arama

Question

İç içe geçmiş bir XML dosyasına sahibim Bazı öğeleri bir dizide aramak ve saklamak istiyorum. Ben bunu nasıl bilemiyorum

....

XML dosyası Sonunda bu diziye alır bu

<?xml version="1.0" encoding="ISO-8859-1"?>

gibi bir şey ....... görünüyor , XML dosyasından elementtree kullanarak numpy dizisine çıkarmak istiyorum.

Herhangi bir öneride yardımcı olabilir.

Teşekkürler!

import xml.etree.ElementTree as ET 
import numpy as np 

tree = ET.parse('input.xml') 
root = tree.getroot() 

a = np.array(
    [ 
     v.text.split() 
     for v in root.findall(".//calculation/varray/v") 
    ], 
    dtype='float' 
) 

print a
