Decode and Encode HTML Entities

Description

Decode and encode HTML entities.

Usage

HTMLdecode(x, named = TRUE, hex = TRUE, decimal = TRUE)
HTMLencode(x, use.iconv = FALSE, encode.only = NULL)

Arguments

`x`	a string (character vector of length one)
`use.iconv`	logical. Should conversion via `iconv` be tried from native encoding to UTF-8?
`named`	logical: replace named character references?
`hex`	logical: replace hexadecimal character references?
`decimal`	logical: replace decimal character references?
`encode.only`	character

Details

HTMLdecode replaces named, hexadecimal and decimal character references as defined by HTML5 (see References) with characters. The resulting character vector is marked as UTF-8 (see Encoding).

HTMLencode replaces UTF-8-encoded substrings with HTML5 named entities (a.k.a. “named character references”). A semicolon ‘;’ will not be replaced by the entity ‘&semi;’. Other than that, however, HTMLencode is quite thorough in its job: it will replace all characters for which named entities exists, even ‘,’ and or ‘&quest;’. You can restrict the characters to be replaced by specifying encode.only.

Value

character

HTMLdecode(c("Max &amp; Moritz", "4 &lt; 9"))
## [1] "Max & Moritz" "4 < 9"

HTMLencode(c("Max & Moritz", "4 < 9"))
## [1] "Max &amp; Moritz" "4 &LT; 9"

HTMLencode("Max, Moritz & more")
## [1] "Max&comma; Moritz &amp; more"
HTMLencode("Max, Moritz & more", encode.only = c("&", "<", ">"))
## [1] "Max, Moritz &amp; more"
