Links in a document

Finds the <a> and <area> elements with an href below the given nodes (and the nodes themselves), in document order, without duplicates. Duplicate destinations are kept, and so are fragment, mailto: and tel: links.

Usage

html_links(x, absolute = FALSE)

Arguments

x

A zuhtml_document or zuhtml_nodeset.

absolute

If TRUE, url is resolved with html_url(); otherwise it is href unchanged.

Value

A data frame with one row per link and character columns text (the link's cleaned text, see html_text_clean()), href (the attribute as written, decoded) and url.
