xml_structure: Show the structure of an html/xml document.

Description

Show the structure of an html/xml document without displaying any of the values. This is useful if you want to get a high level view of the way a document is organised. Compared to xml_structure, html_structure prints the id and class attributes.

Usage

xml_structure(x, indent = 2, file = "")
html_structure(x, indent = 2, file = "")

Arguments

x

HTML/XML document (or part there of)

indent

Number of spaces to ident

file

A connection, or a character string naming the file to print to. If "" (the default), cat prints to the standard output connection, the console unless redirected by sink. If it is "|cmd", the output is piped to the command given by cmd, by opening a pipe connection.

Examples

Run this code
# NOT RUN {
xml_structure(read_xml("<a><b><c/><c/></b><d/></a>"))

rproj <- read_html(system.file("extdata","r-project.html", package = "xml2"))
xml_structure(rproj)
xml_structure(xml_find_all(rproj, ".//p"))

h <- read_html("<body><p id = 'a'></p><p class = 'c d'></p></body>")
html_structure(h)
# }
