filter img="file.svg" to <object data="file.svg">

Hi -

This has been created as an issue before, but sadly the gist is no longer 
available.

I use the plantuml filter to render diagrams to svg. This works, but the 
hyperlinks in the svg are inoperable because the SVG is included as
<p><img src="plantuml-images/9d8236ccdf925ce21eb481c9b4f6da4e7cb52ae1.svg" 
/></p>

When it needs to be something like

<p><object 
data="plantuml-images/d3750ee9e6613d2f461ba5905d7909460bd02f25.svg"></object></p>

What's my easiest route to fixing this (and/or is there an example that's 
close I could modify) ?

TIA,
Nigel

Hi Nigel-san,

I wrote a simple example of lua filter as following (to use, save as 
img2svg.lua).

```
function Para(e)
  for k,v in pairs(e.content) do
    if v.tag == "Image" then
      if string.match(v.src, "svg$") then
        return(pandoc.Para(pandoc.RawInline("html", '<object data="' .. 
v.src .. '"></object>')))
      end
    end
  end
end
```

If you input following markdown file of input.md,

```
![](plantuml-images/9d8236ccdf925ce21eb481c9b4f6da4e7cb52ae1.svg)

```

and then convert by `pandoc -f markdown input.md -t html output.html 
--lua-filter img2svg.lua`. Then you can get

```
<p><object 
data="plantuml-images/9d8236ccdf925ce21eb481c9b4f6da4e7cb52ae1.svg"></object></p>
```

as an output of output.html.(in your example, file name is different but I 
think it is typo.)

Hi Nigel-san,

Sorry, I found more simple way to convert. Previous version has a 
limitation of use (only one <img> in <p> tag).

Updated version is,

```lua
function Image(e)
  if string.match(e.src, "svg$") then
    return(pandoc.RawInline("html", '<object data="' .. e.src .. 
'"></object>'))
  end
end
```

and then you will get,

```html
<p><object 
data="plantuml-images/9d8236ccdf925ce21eb481c9b4f6da4e7cb52ae1.svg"></object></p>
```

as an output.
