I want to change the alt= attribute of an image during translation. This is
my Lua filter:
*function Image(elem) nelem = elem:clone() nelem.attributes.alt =
'image' return nelemend*
It doesn't work, though. With HTML like
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
</head>
<body>
See image: <img src="foo.jpg" alt="foobar"/>
</body>
</html>
I get an AST like this
[ Plain
[ Str "See"
, Space
, Str "image:"
, Space
, Image
( "" , [] , [ ( "alt" , "image" ) ] )
[ Str "foobar" ]
( "foo.jpg" , "" )
]
]
I'm not sure how to interprete the Image part, though. The Markdown output
is:
See image: {alt="image"}
which shows that the original alt text is retained, and the intended
replacement text is just added as if an arbitrary attribute.
What is wrong with my filter?
Thanks, T.
