rvest (version 0.2.0)

xml: Work with xml.

Description

All methods work the same as their HTML equivalents. Currently xml parses XML files as HTML because I can't find another way to ignore namespaces.

Usage

xml(x, ..., encoding = NULL)
xml_tag(x)
xml_attr(x, name, default = NA_character_)
xml_attrs(x)
xml_node(x, css, xpath)
xml_nodes(x, css, xpath)
xml_text(x, ...)
xml_children(x)

Arguments

x

A url, a local path, a string containing html, or a response from an httr request.

...

If x is a URL, additional arguments are passed on to GET().

encoding

Specify encoding of document. See iconvlist() for complete list. If you have problems determining the correct encoding, try stri_enc_detect

name

Name of attribute to extract.

default

A string used as a default value when the attribute does not exist in every node.

css

Nodes to select. Supply one of css or xpath depending on whether you want to use a css or xpath selector.

xpath

Nodes to select. Supply one of css or xpath depending on whether you want to use a css or xpath selector.

Examples

search <- xml("http://stackoverflow.com/feeds")

entries <- search %>% xml_nodes("entry")
entries[[1]] %>% xml_structure()

entries %>% xml_node("author name") %>% xml_text()
entries %>% lapply(. %>% xml_nodes("category") %>% xml_attr("term"))
