+Wasabi [![Build Status](http://travis-ci.org/rubiii/wasabi.png)](http://travis-ci.org/rubiii/wasabi)
+=====
+
+A simple WSDL parser.
+
+
+Installation
+------------
+
+Wasabi is available through [Rubygems](http://rubygems.org/gems/wasabi) and can be installed via:
+
+```
+$ gem install wasabi
+```
+
+
+Getting started
+---------------
+
+``` ruby
+document = Wasabi.document File.read("some.wsdl")
+```
+
+Get the SOAP endpoint:
+
+``` ruby
+document.endpoint
+# => "http://soap.example.com"
+```
+
+Get the target namespace:
+
+``` ruby
+document.namespace
+# => "http://v1.example.com"
+```
+
+Check whether elementFormDefault is set to `:qualified` or `:unqualified`:
+
+``` ruby
+document.element_form_default
+# => :qualified
+```
+
+Get a list of available SOAP actions (snakecase for convenience):
+
+``` ruby
+document.soap_actions
+# => [:create_user, :find_user]
+```
+
+Get a map of SOAP action Symbols, their input tag and original SOAP action name:
+
+``` ruby
+document.operations
+# => { :create_user => { :input => "createUser", :action => "createUser" },
+# =>   :find_user => { :input => "findUser", :action => "findUser" } }
+```
