# HtmlSanitizeEx

`html_sanitize_ex` provides a fast and straightforward HTML Sanitizer written in Elixir which lets you include HTML authored by third-parties in your web application while protecting against XSS. The only dependency is `mochiweb` which is used to parse HTML.

It is the first Hex package to come out of the [elixirstatus.com](http://elixirstatus.com) project, where it is used to sanitize user annoucements around the Elixir community.



## What can it do?

`html_sanitize_ex` parses a given HTML string and, based on the used [Scrubber](https://github.com/rrrene/html_sanitize_ex/tree/master/lib/html_sanitize_ex/scrubber), either completely strips it from HTML tags or sanitizes it by only allowing certain HTML elements and attributes to be present.



## Installation

Add html_sanitize_ex as a dependency in your `mix.exs` file.

```elixir
defp deps do
  [{:html_sanitize_ex, "~> 0.1.0"}]
end
```

After adding you are done, run `mix deps.get` in your shell to fetch the new dependency.



## Usage

It can strip all tags from the given string:

    text = "<a href=\"javascript:alert('XSS');\">text here</a>"
    HtmlSanitizeEx.strip_tags(text)
    # => "text here"

Or allow certain basic HTML elements to remain:

    text = "<h1>Hello <script>World!</script></h1>"
    HtmlSanitizeEx.basic_html(text)
    # => "<h1>Hello World!</h1>"

**TODO: write more comprehensive usage description**
