Read XML data into a Python dictionary

#import module
import xmltodict
 
#open the file
fileptr = open("/home/aditya1117/askpython/plane.xml","r")
 
#read xml content from the file
xml_content= fileptr.read()
print("XML content is:")
print(xml_content)
 
#change xml format to ordered dict
my_ordered_dict=xmltodict.parse(xml_content)
print("Ordered Dictionary is:")
print(my_ordered_dict)
print("Year of plane is:")
print(my_ordered_dict['plane']['year'])
 
#Use contents of ordered dict to make python dictionary
my_plane= dict(my_ordered_dict['plane'])
print("Created dictionary data is:")
print(my_plane)
print("Year of plane is")
print(my_plane['year'])

Output

XML content is:
<?xml version = "1.0" encoding = "utf-8"?>
<!-- xslplane.1.xml -->
<?xml-stylesheet type = "text/xsl"  href = "xslplane.1.xsl" ?>
<plane>
   <year> 1977 </year>
   <make> Cessna </make>
   <model> Skyhawk </model>
   <color> Light blue and white </color>
</plane>
 
Ordered Dictionary is:
OrderedDict([('plane', OrderedDict([('year', '1977'), ('make', 'Cessna'), ('model', 'Skyhawk'), ('color', 'Light blue and white')]))])
Year of plane is:
1977
Created dictionary data is:
{'year': '1977', 'make': 'Cessna', 'model': 'Skyhawk', 'color': 'Light blue and white'}
Year of plane is
1977
