Nokogiri

DESCRIPTION:

Nokogiri (鋸) is an HTML, XML, SAX, and Reader parser. Among Nokogiri's many features is the ability to search documents via XPath or CSS3 selectors.

XML is like violence - if it doesn’t solve your problems, you are not using enough of it.

FEATURES:

  • XPath support for document searching

  • CSS3 selector support for document searching

  • XML/HTML builder

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

SUPPORT:

Before filing a bug report, please read our submission guidelines at:

* http://nokogiri.org/tutorials/getting_help.html

The Nokogiri mailing list is available here:

* http://groups.google.com/group/nokogiri-talk

The bug tracker is available here:

* http://github.com/tenderlove/nokogiri/issues

The IRC channel is #nokogiri on freenode.

SYNOPSIS:

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').each do |link|
  puts link.content
end

####
# Search for nodes by xpath
doc.xpath('//h3/a').each do |link|
  puts link.content
end

####
# Or mix and match.
doc.search('h3.r a.l', '//h3/a').each do |link|
  puts link.content
end

REQUIREMENTS:

  • ruby 1.8 or 1.9

  • libxml2

  • libxml2-dev

  • libxslt

  • libxslt-dev

ENCODING:

Strings are always stored as UTF-8 internally. Methods that return text values will always return UTF-8 encoded strings. Methods that return XML (like to_xml, to_html and inner_html) will return a string encoded like the source document.

WARNING

Some documents declare one particular encoding, but use a different one. So, which encoding should the parser choose?

Remember that data is just a stream of bytes. Only us humans add meaning to that stream. Any particular set of bytes could be valid characters in multiple encodings, so detecting encoding with 100% accuracy is not possible. libxml2 does its best, but it can't be right 100% of the time.

If you want Nokogiri to handle the document encoding properly, your best bet is to explicitly set the encoding. Here is an example of explicitly setting the encoding to EUC-JP on the parser:

doc = Nokogiri.XML('<foo><bar /><foo>', nil, 'EUC-JP')

INSTALL:

  • sudo gem install nokogiri

Binary packages

Binary packages are available for:

DEVELOPMENT:

Developing on C Ruby (MRI)

Developing Nokogiri requires racc and rexical to generate the parser and tokenizer. To start development, make sure you have `libxml2` and `libxslt` installed.

Then install hoe and rake-compiler:

$ gem install hoe rake-compiler racc rexical minitest

Then run rake:

$ rake

Developing on JRuby

Currently, development with JRuby depends on CRuby being installed. With CRuby, install racc and rexical:

$ gem install racc rexical

Make sure hoe and rake compiler are installed with JRuby:

$ jgem install hoe rake-compiler

Then run rake:

$ jruby -S rake
