Convert metadata to a tibble

Source: R/as_eml_tbl.R
as_eml_tbl.Rd

Takes objects of class list or xml_document and converts them to a tibble with a particular structure, designed for storing nested data. Tibbles are required because attributes are stored as list-columns, which are not supported by class data.frame.

Usage

as_eml_tbl(x, ...)

# S3 method for class 'tbl_df'
as_eml_tbl(x, ...)

# S3 method for class 'tbl_lp'
as_eml_tbl(x, ...)

# S3 method for class 'list'
as_eml_tbl(x, ...)

# S3 method for class 'xml_document'
as_eml_tbl(x, ...)

Arguments

x

Object to be converted

...

Other arguments, currently ignored

Value

An object of class tbl_df, tbl and data.frame, containing the following fields:

  • level (int) gives the nestedness level of the node/heading in question

  • label (chr) the xml tag

  • text (chr) Any text stored within that tag

  • attributes (list) Any attributes for that tag

Examples

if (FALSE) { # \dontrun{
df <- xml2::read_xml("https://collections.ala.org.au/ws/eml/dr368") |>
  as_eml_tbl()
} # }
