XML to JSON

Description

Convert XML to a JSON string.

Usage

xml2json(
  xml,
  spaces = 2L,
  linebreaks = FALSE,
  replacer = NULL,
  attributeNamePrefix = "@_",
  textNodeName = "#text",
  ignoreAttributes = FALSE,
  ignoreNameSpace = FALSE,
  parseNodeValue = TRUE,
  parseAttributeValue = TRUE,
  trimValues = TRUE
)

Arguments

xml	either a XML file or some XML given as a character string
spaces	an integer, the indentation
linebreaks	Boolean, whether to break the lines in the JSON string when there are some linebreaks; this generates an invalid JSON string
replacer	character vector, the body of the second argument of JSON.stringify (the replacer function), or NULL
attributeNamePrefix	prefix for the attributes
textNodeName	name of text nodes, which appear for nodes which have both a text content and some attributes
ignoreAttributes	Boolean, whether to ignore the attributes
ignoreNameSpace	Boolean, whether to ignore the namespaces
parseNodeValue	Boolean, whether to parse the node values to numbers if possible
parseAttributeValue	Boolean, whether to parse the attribute values to numbers if possible
trimValues	Boolean, whether to trim the values

Value

A JSON string.

Examples

xml <- system.file("extdata", "order-schema.xml", package = "xml2")
cat(xml2json(xml))
#
js <- c(
  'if(key === "@_type"){',
  '  return undefined;',
  '} else if(key === "@_name"){',
  '  return value.toUpperCase();',
  '}',
  'return value;'
)
cat(xml2json(xml, linebreaks = TRUE, replacer = js))
