There are several approaches you can take. Nokogiri has been a b**** to get going on windows, and even now it only compiles on mingw based MRI AFAIK. To come close to the quality of the Nokogiri gem I think you would need to find a very fast .NET based xml library (it's not XLinq :)), that also has a SAX parser, knows about CSS3 for parsing documents in addition to XPATH, and then provide an adapter to make it look like the nokogiri API. You could potentially use P/Invoke to call to libxml2 but then you take on a dependency on a native library. I'm also not sure if libxml2 actually performs in the same way on windows as it does on *nix.
If we would have an implementation of FFI then we could use the FFI based nokogiri gem. I looked at it a few times but it would be a serious amount of work, too much for my taste :). --- Met vriendelijke groeten - Best regards - Salutations Ivan Porto Carrero Web: http://whiterabbitconsulting.eu - http://flanders.co.nz Twitter: http://twitter.com/casualjim Author of IronRuby in Action (http://manning.com/carrero) Microsoft IronRuby/C# MVP On Tue, Apr 20, 2010 at 12:22 AM, Chris Bilson <cbil...@pobox.com> wrote: > Just out of curiosity: What's the process for making an ironruby port of > something like Nokogiri? > > I looked at a blog > post<http://blog.headius.com/2010/04/nokogiri-java-port-help-us-finish-it.html>by > one of the people working on the JRuby port and it looks pretty involved, > but essentially, to port it you would just implement all the > "attach_functions" in libxml.rb in .NET? > > > --c > > > > On Sun, Apr 18, 2010 at 18:46, Tomas Matousek < > tomas.matou...@microsoft.com> wrote: > >> Using native code in your app also requires full trust (implying it won't >> work in Silverlight) and is potentially a security issue.
