XMLTextDocument: XML Text Documents

In tm: Text Mining Package

Description

Create XML text documents.

Usage

XMLTextDocument(x = xml_missing(),
                author = character(0),
                datetimestamp = as.POSIXlt(Sys.time(), tz = "GMT"),
                description = character(0),
                heading = character(0),
                id = character(0),
                language = character(0),
                origin = character(0),
                ...,
                meta = NULL)

Arguments

x	An XMLDocument.
author	a character or an object of class person giving the author names.
datetimestamp	an object of class POSIXt or a character string giving the creation date/time information. If a character string, exactly one of the ISO 8601 formats defined by https://www.w3.org/TR/NOTE-datetime should be used. See parse_ISO_8601_datetime in package NLP for processing such date/time information.
description	a character giving a description.
heading	a character giving the title or a short heading.
id	a character giving a unique identifier.
language	a character giving the language (preferably as IETF language tags, see language in package NLP).
origin	a character giving information on the source and origin.
...	user-defined document metadata tag-value pairs.
meta	a named list or NULL (default) giving all metadata. If set all other metadata arguments are ignored.

Value

An object inheriting from XMLTextDocument and TextDocument.

                        id = xml,
