Multiple tables in HTML

[sjackman]

Can the which parameter of import be used to extract the first/second/etc table from an HTML document with multiple tables?

Not at present. But that should be pretty easy to implement with a change to this line: https://github.com/leeper/rio/blob/master/R/import_methods.R#L333

I'll put it on the TODO list.

Thanks!

I'm pushing an update with this feature momentarily. It will also be shipping to CRAN today.

Thanks for the quick implementation, Thomas! This gives a not-to-elegant but quite workable solution for reading multiple PSV tables from a Markdown document by rendering them to HTML and reading them with rio::import.

Does rio have a function to extract all tables from a given document (HTML, XLSX, et c) and return a list of data frames? It would be quite useful, particularly a named list, when the data format has names, like sheet names.

I am pushing a commit with support for this via a new function, import_list(), that will handle both a multi-object file (HTML, xlsx) OR a vector of multiple file names.

Beautiful!
