Nokogiri

Module Nokogiri

Nokogiri parses and searches XML/HTML very quickly, and also has correctly implemented CSS3 selector support as well as XPath support.

Parsing a document returns either a Nokogiri::XML::Document, or a Nokogiri::HTML::Document depending on the kind of document you parse.

Here is an example:

require 'nokogiri'
require 'open-uri'

# Get a Nokogiri::HTML:Document for the page we’re interested in...

doc = Nokogiri::HTML(open('http://www.google.com/search?q=tenderlove'))

# Do funky things with it using Nokogiri::XML::Node methods...

####
# Search for nodes by css
doc.css('h3.r a.l').each do |link|
  puts link.content
end

See Nokogiri::XML::Node#css for more information about CSS searching. See Nokogiri::XML::Node#xpath for more information about XPath searching.

Public Class Methods

HTML(thing, url = nil, encoding = nil, options = XML::ParseOptions::DEFAULT_HTML, &block) Show Source: Parse HTML. Convenience method for Nokogiri::HTML::Document.parse; # File lib/nokogiri/html.rb, line 12 def HTML thing, url = nil, encoding = nil, options = XML::ParseOptions::DEFAULT_HTML, &block Nokogiri::HTML::Document.parse(thing, url, encoding, options, &block) end

Slop(*args, &block) Show Source

Parse a document and add the Slop decorator. The Slop decorator implements method_missing such that methods may be used instead of CSS or XPath. For example:

  doc = Nokogiri::Slop(<<-eohtml)
    <html>
      <body>
        <p>first</p>
        <p>second</p>
      </body>
    </html>
  eohtml
  assert_equal('second', doc.html.body.p[1].text)

# File lib/nokogiri.rb, line 97
    def Slop(*args, &block)
      Nokogiri(*args, &block).slop!
    end

XML(thing, url = nil, encoding = nil, options = XML::ParseOptions::DEFAULT_XML, &block) Show Source: Parse XML. Convenience method for Nokogiri::XML::Document.parse; # File lib/nokogiri/xml.rb, line 32 def XML thing, url = nil, encoding = nil, options = XML::ParseOptions::DEFAULT_XML, &block Nokogiri::XML::Document.parse(thing, url, encoding, options, &block) end

XSLT(stylesheet) Show Source

Create a Nokogiri::XSLT::Stylesheet with stylesheet.

Example:

  xslt = Nokogiri::XSLT(File.read(ARGV[0]))

# File lib/nokogiri/xslt.rb, line 12
    def XSLT stylesheet
      XSLT.parse(stylesheet)
    end

make(input = nil, opts = {}) Show Source: Create a new Nokogiri::XML::DocumentFragment; # File lib/nokogiri.rb, line 74 def make input = nil, opts = {}, &blk if input Nokogiri::HTML.fragment(input).children.first else Nokogiri(&blk) end end

parse(string, url = nil, encoding = nil, options = nil) Show Source: Parse an HTML or XML document. string contains the document.; # File lib/nokogiri.rb, line 55 def parse string, url = nil, encoding = nil, options = nil doc = if string.respond_to?(:read) || string =~ /^\s*<[^Hh>]*html/i # Probably html Nokogiri::HTML( string, url, encoding, options || XML::ParseOptions::DEFAULT_HTML ) else Nokogiri::XML(string, url, encoding, options || XML::ParseOptions::DEFAULT_XML) end yield doc if block_given? doc end

An HTML, XML, SAX, & Reader parser with the ability to search documents via XPath or CSS3 selectors… and much more
