# SaxHtml
Simple SAX-like parser for HTML.
It accepts an html string and an anonymous callback function that fires for every event
```elixir
html_text = """
<html>
<head>
<title>Gregors</title>
</head>
<body>
<div>
<p>Howdy!!!</p>
</div>
</body>
</html>
"""
handler = fn {event, data, state} -> IO.puts("#{event} - #{data}") end
SaxHtml.parse(html_text, handler)
start_tag - html
characters -
start_tag - head
characters -
start_tag - title
characters - Gregors
end_tag - title
characters -
end_tag - head
characters -
start_tag - body
characters -
start_tag - div
characters -
start_tag - p
characters - Howdy!!!
end_tag - p
characters -
end_tag - div
characters -
end_tag - body
characters -
end_tag - html
characters -
```
Or with `state`. State must be returned from the callback
```
handler = fn
{ :characters, chars, state} -> [ chars | state ]
{ _, _, state} -> state
end
SaxHtml.parse(html_text, handler, []) |> Enum.join("") |> IO.inspect
"\n\n\n \n Howdy!!!\n \n \n \n Gregors\n \n "
```
