Re: Problems using the RedCloth gem !?!
I think it filters some HTML tags, but not normal and safe ones like <br />, <p>, <h1> etc. On Jan 21, 11:42 am, Emil Kampp <rails-mailing-l...-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote:> Hi there. > > I have this line in my view: > > <%= RedCloth.new(@news.long, [:filter_html, > :filter_styles]).to_html(:textile) %> > > but it doesn''t filter out the html out, from this input: > > --------- > h1.

Is there any way, that i can filter all html tags from the text, while rendering it with the gem ? - Emil -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If there is, I haven''t found it. I _have_ though found a useful Regex
for
doing that. It''s a slightly modified version of the one used in Typo.
[No
source code will go scavenged!] I know I might catch some flack for doing so
but I choose to add this method to the String class itself, as I use it a
lot.
class String
def strip_html(leave_whitespace = false)
name = /[\w:_-]+/
value =
/([A-Za-z0-9]+|(''[^'']*?''|"[^"]*?"))/
attr = /(#{name}(\s*=\s*#{value})?)/
rx
/<[!\/?\[]?(#{name}|--)(\s+(#{attr}(\s+#{attr})*))?\s*([!\/?\]]+|--)?>/
(leave_whitespace) ? self.gsub(rx, "").strip : self.gsub(rx,
"").gsub(/\s+/, " ").strip
end
end
Be aware, though, that there is stil a lot of HTML entities left in the
Textilized string. [™, etc.] Depending on your end use, you may need
to strip those entities as well. Let me know if you do need that because
I''ve written some really handy code for it, completely based on what
transformations RedCloth does. You know, only make the server work as hard
as it has to.

I do need to remove ALL HTML enteties from the text, before rendering it. Is there any way to allow only some redcloth formatting to be enterpreted ? such as not enterpreting lets say the h1. tag but accept the h2. tag ? - Emil -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

In what circumstances would you want an h1 and not an h2? Sounds like
you''re
definitely going to need to Regex that one.
Anyhow, here''s the two additional methods [both on the String class as
before] for dealing with RedClothed HTML entities.
def strip_accents
self.gsub(/&([A-Za-z])(grave|acute|circ|tilde|uml|ring|lig|cedil);/,
''\1'')
end
def convert_entities
dummy = self.dup
{
"#822[01]" => "\"",
"#821[67]" => "''",
"#8230" => "...",
"#8211" => "-",
"#8212" => "--",
"#215" => "x",
"gt" => ">",
"lt" => "<",
"(#8482|trade)" => "(tm)",
"(#174|reg)" => "(r)",
"(#169|copy)" => "(c)",
"(#38|amp)" => "&",
"nbsp" => " ",
"cent" => " cent",
"pound" => " pound",
}.each do |textiled, normal|
dummy.gsub!(/&#{textiled};/, normal)
end
dummy.gsub(/&[^;]+;/, "")
end
