fluentxpath¶ ↑

• github.com/douglassquirrel/fluentxpath

With the fluentxpath Ruby gem, you build your xpath query in a language that is nearly English and very readable.

• Navigate to root element or arbitrary element

• Navigate to children and descendants

• Specify tag name and attribute values

• Everything else is missing!

require 'fluentxpath'
xpath = Fluentxpath::XPath
xpath.that_navigates { to_root_element.with_name("library") }     # "/library"
xpath.that_navigates { to_any_element.with_name("book") }         # "//book"
xpath.that_navigates { to_root_element.with_name "library"
                       and_then.to_children.with_name "subject" 
                       and_then.to_children.with_name "shelf" }   # "/library/subject/shelf"
xpath.that_navigates { to_root_element.with_name "library"
                       and_then.to_descendants.with_name "book" } # "/library//book"
xpath.that_navigates { to_any_element.with_name("book")
                                      and_attributes("title"  => "The Conquest of Bread", 
                                                     "author" => "Kropotkin") }  # "//book[@author='Kropotkin' and @title='The Conquest of Bread']"
# See /test for many more

• None, though you will want something that can use your xpath expression (like Nokogiri)

• sudo gem install fluentxpath
