nokogiri version 1.1.1 has been released!

Nokogiri (��) is an HTML, XML, SAX, and Reader parser.

Changes:

### 1.1.1

\* New features

&nbsp;&nbsp;\* Added XML::Node#elem?  
&nbsp;&nbsp;\* Added XML::Node#attribute\_nodes  
&nbsp;&nbsp;\* Added XML::Attr  
&nbsp;&nbsp;\* XML::Node#delete added.  
&nbsp;&nbsp;\* XML::NodeSet#inner\_html added.

\* Bugfixes

&nbsp;&nbsp;\* Not including an HTML entity for \r for HTML nodes.  
&nbsp;&nbsp;\* Removed CSS::SelectorHandler and XML::XPathHandler  
&nbsp;&nbsp;\* XML::Node#attributes returns an Attr node for the value.  
&nbsp;&nbsp;\* XML::NodeSet implements to\_xml

## FEATURES:

\* XPath support for document searching  
\* CSS3 selector support for document searching  
\* XML/HTML builder  
\* Drop in replacement for Hpricot (though not bug for bug)

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

Here is a speed test:

&nbsp;&nbsp;\* [http://gist.github.com/24605](http://gist.github.com/24605)

Nokogiri also features an Hpricot compatibility layer to help ease the change  
to using correct CSS and XPath.

Thanks Aaron for your work on Nokogiri.

I noticed what looked like JRuby support so I tried installing the gem  
(worked) and then an example that failed:

irb(main):001:0\> require 'nokogiri'  
=\> true  
irb(main):002:0\> require 'open-uri'  
=\> true  
irb(main):003:0\> doc = Nokogiri::HTML(open('[http://markwatson.com](http://markwatson.com)'))  
NoMethodError: undefined method `read\_memory' for  
Nokogiri::HTML::Document:Class  
&nbsp;&nbsp;from /Users/markw/bin/jruby/lib/ruby/gems/1.8/gems/nokogiri-1.1.1-  
java/lib/nokogiri/html.rb:36:in `parse'  
&nbsp;&nbsp;from /Users/markw/bin/jruby/lib/ruby/gems/1.8/gems/nokogiri-1.1.1-  
java/lib/nokogiri/html.rb:15:in `HTML'  
&nbsp;&nbsp;from (irb):4  
&nbsp;&nbsp;from /Users/markw/bin/jruby/lib/ruby/1.8/irb.rb:150:in `eval\_input'

I am using version jruby 1.1.5 - will a later version of JRuby make  
this work?

Thanks,  
Mark

No. Unfortunately the jruby release is sort of a lie.... It doesn't  
actually work on jruby. I've been releasing a jruby version so that  
webrat can use it's CSS to XPath conversion code, then fall back on  
REXML.

We're working on a better jruby solution though. We've got a branch  
that uses FFI, and Charles Nutter has a branch with a Java  
implementation.

&nbsp;&nbsp;[GitHub - headius/nokogiri: Nokogiri (鋸) is a Rubygem providing HTML, XML, SAX, and Reader parsers with XPath and CSS selector support.](http://github.com/headius/nokogiri/tree/master)

I'm not sure what the status is on his branch.

Thanks Aaron for the update on Charles' and your branches. I am using  
nokogiri in 2 examples in a new Ruby book that I am writing for  
APress; I had a warning about JRuby incompatibility (and have a little  
code using a pure Ruby alternative), but by the time the book is  
published (5 months) it looks like we will have a working version for  
JRuby. I could be of more help with the pure Java version, so I will  
as Charles if he wants help.
