# 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) click to toggle source

Parse HTML. Convenience method for Nokogiri::HTML::Document.parse

    # File lib/nokogiri/html.rb, line 14
    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) click to toggle 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 108
    def Slop(*args, &block)
      Nokogiri(*args, &block).slop!
    end

XML(thing, url = nil, encoding = nil, options = XML::ParseOptions::DEFAULT_XML, &block) click to toggle 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, modules = {}) click to toggle 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, modules = {}
      XSLT.parse(stylesheet, modules)
    end

make(input = nil, opts = {}) click to toggle source

Create a new Nokogiri::XML::DocumentFragment

    # File lib/nokogiri.rb, line 85
    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) click to toggle source

Parse an HTML or XML document. `string` contains the document.

    # File lib/nokogiri.rb, line 66
    def parse string, url = nil, encoding = nil, options = nil
      doc =
        if string.respond_to?(:read) ||
          string =~ /^\s*<[^Hh>]*html/ # 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
