Where to find a list of all the possible HTML tags in Python?

Question

Is there a standard module in Python that lists all the HTML tags?

For example, I would like to do things like:

if is_valid_html_tag('div'):
   print 'div is a valid tag'

if is_not_valid_html_tag('boda'):
   print 'boda is not a valid tag'

To do this I need a list of all tags in Python. I wonder if someone has assembled them already or maybe included in xml or some other html module in Python library?

Thanks, Boda Cydo.

Answer 1

I don't know whether there is a built in module that does just that. I'd suggest finding a list of tags, then writing a function like this...

def is_valid_html_tag(tag_name):  
  tags=["a","abbr","acronym","address","area","b","base","bdo","big","blockquote","body","br","button","caption","cite","code","col","colgroup","dd","del","dfn","div","dl","DOCTYPE","dt","em","fieldset","form","h1","h2","h3","h4","h5","h6","head","html","hr","i","img","input","ins","kbd","label","legend","li","link","map","meta","noscript","object","ol","optgroup","option","p","param","pre","q","samp","script","select","small","span","strong","style","sub","sup","table","tbody","td","textarea","tfoot","th","thead","title","tr","tt","ul","var"]
  return tag_name in tags

I think the list of valid tags depends on your doctype. These came from http://htmldog.com/reference/htmltags/. They say this list is for Strict XHTML.

That said, there may be a better way to accomplish what you're trying to do. I'm sure the friendly folks here would be happy to help if you'd like to provide more details on your goal.

Answer 2

Since python has all kinds of modules - smtp, xml, etc, the question asks if there is a module like htmltags that would list all the valid html tags.

When you search the http://docs.python.org site, you didn't find any such thing, did you?

When you googled, you found this, right?

What's wrong with that Recipe 366000? Why didn't you mention it in your question? What didn't you like about it?
