How do I strip tags that have already been filtered?

I have this model being created by a third party, and I need to access this model and remove tags, I thought I could just use the |removetag filter, but it seems the tags are pre-escaped for the model, anyone have some advice on how else I could remove these tags from the template side?

It depends on what you mean by 'already filtered'; can you provide any example string?

Does running it through |safe|removetags help?

I imagine you're also aware that you can use |striptags if you wish to remove all tags.

EDIT: Example data uploaded.

OK, if your strings look like that, you'll need to create the reverse of the django "escape" filter -- e.g. in one of your apps create a templatetags module, create unescape.py:

from django import template
from django.utils.safestring import mark_safe
from django.utils.encoding import force_unicode

register = template.Library()

@register.filter
def unescape(value):
    return mark_safe(force_unicode(value).replace('&lt;', '<').replace('&gt;', '>').replace('&quot;', '"').replace('&#39;', "'").replace('&amp;', '&'))

Don't forget to create an __init__.py in the templatetags directory also, and then restart your server so it gets registered.

Then in your templates:

{% load unescape %}
...
{{ example_string|unescape }}

See http://docs.djangoproject.com/en/dev/howto/custom-template-tags/ for better instructions if you haven't done this before.

Alternatively you could just run this on your models in python code somewhere, but your question asked about "the template side".
