  item_nodes = NULL,
  collection_nodes = NULL,
  excludeFiles = NULL,
  ...
)

Arguments

filename	name of XML file or vector of XML filenames.
item_nodes	list of item nodes defining path, vector of nodes and node types (text/attrs).
collection_nodes	list of collection nodes defining path, vector of nodes and vector of node types (text/attrs).
excludeFiles	vector of filenames excluded from XML to CSV conversion.
...	auxiliary parameters.

Value

Returns the dataframe object with rows (observations matching item/collection nodes) and columns (item nodes).

Examples

library(HooverArchives)

item_nodes = list(path = "(//c)|(//c01)|(//c02)|(//c03)",
                  nodes = c("primarynode", ".//unittitle", "./did//unitdate"),
                  types = c("attrs", "text", "text"))
# "primarynode" extracts the data from the root nodes.

collection_nodes <- list(path="archdesc[@level='collection']",
                        nodes=c(".//unittitle", "./did//unitdate"),
                        types=c("text", "text"))

filedata <- fromXMLtoCSV(system.file("rusdata.xml", package="HooverArchives"),
                         item_nodes, collection_nodes)
