xml_dtd

Construct a document type definition

Description

This is used to create simple document type definitions. If you need to create a more complicated definition with internal subsets it is recommended to parse a string directly with read_xml().

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

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(
'<!DOCTYPE doc [
<!ELEMENT doc (#PCDATA)>
<!ENTITY foo " test ">
]>
<doc>This is a valid document &foo; !</doc>')
