Re: Two treatments of same input file

[Bastien DUMONT <bastien.dumont-VwIFZPTo/vqsTnJN9+BGXg@public.gmane.org>]

You can handle all of this using a Lua filter. Assuming that your first heading will always start with "A" and the second with "Code to Produce a", I rewrote slightly your input in test.md:

```
~~~ {.html heading="Form with a Button"}
<form>
<input id="b1" type="button" value="Apply" title="Button"/>
</form>
~~~
```

Then I wrote in test.lua:

```
local HEADING_LEVEL = 2

function CodeBlock(block)
  if block.attr.attributes.heading then
    local raw_heading = block.attr.attributes.heading
    local html_object_heading = pandoc.Header(HEADING_LEVEL, 'A ' .. raw_heading)
    local html_object = pandoc.RawBlock('html5', block.text)
    local code_block_heading = pandoc.Header(HEADING_LEVEL, 'Code to produce a ' .. raw_heading)
    return { html_object_heading, html_object, code_block_heading, block }
  end
end
```

With the command pandoc test.md -L test.lua, I got the desired result.

You may want to modify it in order to adapt it to your real needs (like setting a "header-level" attribute on your raw block, etc.)
