Adding Elements to a Dictionary in Python

I have used BeautifulSoup parser to parse an xml document. Here is the code below. I want to put all the elements into a single dictionary. 

import requests
from bs4 import BeautifulSoup 

f = open('/home/soundarya/Desktop/mv-v18-1526.nxml','r')

d = BeautifulSoup(f.read())

s = d.find('journal-meta')

j = s.findAll('journal-id')
print s.find('journal-title').renderContents()

print s.find('issn').renderContents()

print s.find('publisher-name').renderContents()

for x in j:
    print x.renderContents()

I got the output for this as elements :

/usr/local/lib/python2.7/dist-packages/bs4/__init__.py:166: UserWarning: No parser was explicitly specified, so I'm using the best available HTML parser for this system ("lxml"). This usually isn't a problem, but if you run this code on another system, or in a different virtual environment, it may use a different parser and behave differently.

To get rid of this warning, change this:

 BeautifulSoup([your markup])

to this:

 BeautifulSoup([your markup], "lxml")

  markup_type=markup_type))

I tried using like :

import requests
from bs4 import BeautifulSoup 

f = open('/home/soundarya/Desktop/mv-v18-1526.nxml','r')

d = BeautifulSoup(f.read())

a = {}
a['journal-meta'] = d.find('journal-meta')
a['journal-id'] = a.find('journal-id')
a['journal-title'] = a.find('journal-title').renderContents()
a['issn'] = a.find('issn').renderContents()
a['publisher-name'] = a.find('publisher-name').renderContents()

for x in a:
    print x.renderContents()

I am getting this error:

AttributeError: 'dict' object has no attribute 'find'

Help me to put the elements in a dictionary.

a['journal-id'] = a.find('journal-id')

I think you wanted to use variable d:

a['journal-id'] = d.find('journal-id')

Generally, try to use more descriptive variable names.
