Method: Slaw::Render::HTMLRenderer#render_node

Defined in:
lib/slaw/render/html.rb

#render_node(node, base_url = '') ⇒ String

Transform just a single node and its children into HTML.

If elem has an id, we use xpath to tell the XSLT which element to transform. Otherwise we copy the node into a new tree and apply the XSLT to that.

Parameters:

  • node to render

  • (defaults to: '')

    root URL for relative URLs (cannot be empty)

Returns:
