Ruby/XML/Smart is freely distributable according to the terms of the GNU Lesser General Public License (see the file 'COPYING').

This program is distributed without any warranty. See the file 'COPYING' for details.

• Based on Nokogiri 1.5.5
• Thus works for MRI ruby 1.8.7, 1.9.x, JRuby (basically everything that is Nokogiri ready)
• Works on Linux, OSX, Windows

• Nokogiri is messy - violence always is
• libxml smells like old-school C-Binding ;-)
• rex is ... strange

Sorry, no css selectors, html, ... go to Nokogiri if you look for these.

Use namespaces in xpaths without any additional work:

  doc = XML::Smart.string('<test xmlns:aaa="uri:aaa"><aaa:test/></test>')
  doc.find('string(aaa:test)')
  doc.close

Register your own shortcusts to be available in all XPaths:

  doc = XML::Smart.string('<test xmlns:aaa="uri:aaa"><aaa:test/></test>')
  doc.register_namespace :a, 'uri:aaa'
  doc.find('string(a:test)')
  doc.close

  XML::Smart.modify("EXAMPLE.xml","<test><names/></test>") do |doc|
    doc.root.add "test_node"
  end

Libxml2, the basis for nokogiri has only partial xml-schema support, but full relaxng support. Thus checking against xml-schema with nokogiri may return positive results, although it is a lie. XML::Smart internally converts xml-schema to relaxng, thus allowing for seamless schema usage:

  doc = XML::Smart.string('<test xmlns:aaa="uri:aaa"><aaa:test/></test>')
  doc.validate_against(XML::Smart.open_unprotected('xmlschema.xml'))
  doc.validate_against(XML::Smart.open_unprotected('xmlschema.xml'))
  doc.find('string(a:test)')
  doc.close

Libxml2, the basis for nokogiri does not support https xincludes. Nokogiri may impelement this in the future (issue sparklemotion/nokogiri#1321), but for now we do support it:

  doc.xinclude!

or

  doc.find('//someelement').first.xinclude!

• qname instead of name
• #register_namespace instead of #namespaces= to register shortcuts
• no more namespaces for #find necessary, all namespaces in document are automatically available.
• signals removed
• pull parser removed

Sorry, no inline code documentation yet. We have an extensive test suite, look for examples there for now.
