Set alt attribute for image nodes; extract images from HTML blocks

Markdown specification is not always clear about what goes in the text part of an image. Pandoc specifies a markdown image as alt="alt text" Since commonmark does not recognize the alt-text, we need to find it ourselves.

Usage

process_images(images, ns = tinkr::md_ns())

Arguments

images: an XML nodelist that contains blocs with image information
ns: the namespace to use

Value

a copy of the nodelist

Details

Moreover, it's possible to include HTML images, so we need to parse the HTML to expose the alt text.
