download_xml

Download a HTML or XML file

Description

Libcurl implementation of C_download (the "internal" download method) with added support for https, ftps, gzip, etc. Default behavior is identical to download.file(), but request can be fully configured by passing a custom curl::handle().

Usage

download_xml(
  url,
  file = basename(url),
  quiet = TRUE,
  mode = "wb",
  handle = curl::new_handle()
)

download_html(
  url,
  file = basename(url),
  quiet = TRUE,
  mode = "wb",
  handle = curl::new_handle()
)

Arguments

`url`	A character string naming the URL of a resource to be downloaded.
`file`	A character string with the name where the downloaded file is saved.
`quiet`	If `TRUE`, suppress status messages (if any), and the progress bar.
`mode`	A character string specifying the mode with which to write the file. Useful values are `"w"`, `"wb"` (binary), `"a"` (append) and `"ab"`.
`handle`	a curl handle object

Details

The main difference between curl_download and curl_fetch_disk is that curl_download checks the http status code before starting the download, and raises an error when status is non-successful. The behavior of curl_fetch_disk on the other hand is to proceed as normal and write the error page to disk in case of a non success response.

Value

Path of downloaded file (invisibly).

Examples

## Not run: 
download_html("http://tidyverse.org/index.html")

## End(Not run)
