How do I perform HTML decoding encoding using Python Django

Question

I have a string that is HTML encoded        amp lt img class  amp quot size-medium wp-image-113 amp quot    style  amp quot margin-left  15px  amp quot  title  amp quot su1 amp quot    src  amp quot http   blah org wp-content uploads 2008 10 su1-300x194 jpg amp quot    alt  amp quot  amp quot  width  amp quot 300 amp quot  height  amp quot 194 amp quot    amp gt       I want to change that to    lt img class  size-medium wp-image-113  style  margin-left  15px      title  su1  src  http   blah org wp-content uploads 2008 10 su1-300x194 jpg     alt    width  300  height  194    gt     I want this to register as HTML so that it is rendered as an image by the browser instead of being displayed as text    The string is stored like that because I am using a web-scraping tool called BeautifulSoup  it  scans  a web-page and gets certain content from it  then returns the string in that format   I ve found how to do this in C  but not in Python  Can someone help me out   Related   Convert XML HTML Entities into Unicode String in Python

If anyone is looking for a simple way to do this via the django templates, you can always use filters like this:

<html>
{{ node.description|safe }}
</html>

I had some data coming from a vendor and everything I posted had html tags actually written on the rendered page as if you were looking at the source.

Use daniel s solution if the set of encoded characters is relatively restricted  Otherwise  use one of the numerous HTML-parsing libraries   I like BeautifulSoup because it can handle malformed XML HTML    http   www crummy com software BeautifulSoup   for your question  there s an example in their documentation   from BeautifulSoup import BeautifulStoneSoup BeautifulStoneSoup  Sacr amp eacute  bl amp  101 u                        convertEntities BeautifulStoneSoup HTML ENTITIES  contents 0    u Sacr xe9 bleu

Daniel s comment as an answer    escaping only occurs in Django during template rendering  Therefore  there s no need for an unescape - you just tell the templating engine not to escape  either    context var safe    or    autoescape off      context var      endautoescape
