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().

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>')
