Maybe everyone knews about this, but I didn't and searching across the
web I found many sophisticated and weird methods to handle html
entities.
But so far there is a module xml.sax.saxutils, which together with
urlib.quote*() and urlib.unquote*() provides every possible conversion/
encoding/decoding from/to html entities.
I wrote some examples, maybe for someone it will be usefull.
#!/usr/bin/python
from xml.sax import saxutils
import urllib
# ===== QUOTE Examples =====
print "urllib.quote_plus('<p> hello & world </p>'):"
quotePlusOutput = urllib.quote_plus('<p> hello & world </p>')
print quotePlusOutput,'\n'
print "urllib.unquote_plus('%s'):" % quotePlusOutput
print urllib.unquote_plus(quotePlusOutput),'\n'
# ===== Entities Examples =====
entities = {' ':' '}
print "saxutils.escape('<p> hello & world </p>', entities):"
saxEscapeOutput = saxutils.escape('<p> hello & world </p>',
entities)
print saxEscapeOutput,'\n'
entities={' ':' '}
print "saxutils.unescape('%s', entities):" % saxEscapeOutput
print saxutils.unescape( saxEscapeOutput, entities)
