you can also use ruby library Sanitize (http://wonko.com/pos...)

This library can make you parse html template very easily.

let's see the following examples.

Using Sanitize is easy. First, install it:
sudo gem install sanitize

Then call it like so:

require 'rubygems'
require 'sanitize'

html =3D '<b><a href=3D"http://foo....>foo</a></b&... =
src=3D"http://foo.com/...
" />'

Sanitize.clean(html) # =3D> 'foo'

By default, Sanitize removes all HTML. You can use one of the built-in =20=

configs to tell Sanitize to allow certain attributes and elements:

Sanitize.clean(html, Sanitize::Config::RESTRICTED)
# =3D> '<b>foo</b>'

Sanitize.clean(html, Sanitize::Config::BASIC)
# =3D> '<b><a href=3D"http://foo.... rel=3D"nofollow">foo</a></b>'

Sanitize.clean(html, Sanitize::Config::RELAXED)
# =3D> '<b><a href=3D"http://foo....>foo</a></b&... =
src=3D"http://foo.com/...
" />'

Or, if you=A1=AFd like more control over what=A1=AFs allowed, you can =
provide =20
your own custom configuration:

Sanitize.clean(html, :elements =3D> ['a', 'span'],
:attributes =3D> {'a' =3D> ['href', 'title'], 'span' =3D> =
['class']},
:protocols =3D> {'a' =3D> {'href' =3D> ['http', 'https', =
'mailto']}})

good one :)
