How to access Senseval data from NLTK?

import nltk
#from nltk.corpus import senseval as ss

# This shows what files from senseval are in NLTK. sadly there's only 4.
print nltk.corpus.senseval.fileids()

# This yields the line by line xml version of the senseval data.
# note the "\n" are also in each line.
print nltk.corpus.senseval.raw()

# Most probably the individual instances are what you wanted to get.
for id in nltk.corpus.senseval.fileids():
  # This access all instances from each file.
  insts = nltk.corpus.senseval.instances(id)
  # Looping through the instances.
  for i in insts:
    print i
    # SensevalInstance returns (word, position, context, senses),
    # so you can each variable as such:
    print i.word, i.position, i.senses
    print i.context
