xml_dtd: Construct a document type definition

Usage

xml_dtd(name = "", external_id = "", system_id = "")

Arguments

name

The name of the declaration

external_id

The external ID of the declaration

system_id

The system ID of the declaration

Examples

Run this code
r <- xml_new_root(
  xml_dtd(
    "html",
    "-//W3C//DTD XHTML 1.0 Transitional//EN",
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
  )
)

# Use read_xml directly for more complicated DTD
d <- read_xml(
  '

]>
This is a valid document &foo; !'
)
