This gem validates XML against it's XSD that is created from xsi:schemaLocation elements.

It does this by first parsing the XML and searching for elements that include xsi:schemaLocation attributes. It then creates an XSD schema document that includes the root namespace and further imports additional namespaces discovered in the XML.

It then validates the document against that constructed schema document and outputs any error messages.

Note: this gem utilizes the 'nokogiri' gem (which in turn relies on Gnome's libxml2) for the XML parsing and schema validation.

Add this line to your application's Gemfile:

gem 'validate_xml_xsi'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install validate_xml_xsi

validate_xml_xsi
