  spaces = 2L,
  linebreaks = FALSE,
  replacer = NULL,
  attributeNamePrefix = "@_",

  ignoreAttributes = FALSE,
  ignoreNameSpace = FALSE,
  parseNodeValue = TRUE,
  parseAttributeValue = TRUE,
  trimValues = TRUE
)

xml

either a XML file or some XML given as a character string

spaces

an integer, the indentation

  '  return undefined;',
  '} else if(key === "@_name"){',

  '}',
  'return value;'
)
cat(xml2json(xml, linebreaks = TRUE, replacer = js))
