The default Django urlize filter does not work with html nicely so here I've used an HTML parser BeautifulSoup to quickly search through each text node and run the django urlize filter on it.

Optimizations could be made to include a regex in the soup.findAll() method's text argument to only search those text nodes which matched a url pattern. You could also modify the method to convert the text to urls, such as using your own custom url filter.

@register.filter("urlize_html")
def urlize_html(html):
    """
    Returns urls found in an (X)HTML text node element as urls via Django urlize filter.
    """
    try:
        from BeautifulSoup import BeautifulSoup
        from django.utils.html import urlize
    except ImportError:
        if settings.DEBUG:
            raise template.TemplateSyntaxError, "Error in urlize_html The Python BeautifulSoup libraries aren't installed."
        return html
    else:
        soup = BeautifulSoup(html)
           
        textNodes = soup.findAll(text=True)
        for textNode in textNodes:
            urlizedText = urlize(textNode)
            textNode.replaceWith(urlizedText)
            
        return str(soup)
