Reads a PMC XML file and returns its metadata as a one-row data frame: journal, publisher, article title, authors and affiliations, identifiers (PMID, PMCID, DOI), publication dates, and figure / table / reference counts.

Usage

rt_meta_pmc(filename, remove_ns = FALSE)

Arguments

filename: The path to the PMC XML file as a string.
remove_ns: TRUE if an XML namespace should be removed, else FALSE (default).

Value

A one-row tibble of metadata. The column `is_success` indicates whether the file was parsed successfully.

# \donttest{
filepath <- system.file(
  "extdata", "PMID32171256-PMC7071725.xml", package = "rtransparency"
