Method: Nokogiri::XML::Document#remove_namespaces!

Defined in:

ext/nokogiri/xml_document.c

#remove_namespaces! ⇒ Object

Remove all namespaces from all nodes in the document.

This could be useful for developers who either don’t understand namespaces or don’t care about them.

The following example shows a use case, and you can decide for yourself whether this is a good thing or not:

doc = Nokogiri::XML <<-EOXML
   <root>
     <car xmlns:part="http://general-motors.com/">
       <part:tire>Michelin Model XGV</part:tire>
     </car>
     <bicycle xmlns:part="http://schwinn.com/">
       <part:tire>I'm a bicycle tire!</part:tire>
     </bicycle>
   </root>
   EOXML

doc.xpath("//tire").to_s # => ""
doc.xpath("//part:tire", "part" => "http://general-motors.com/").to_s # => "<part:tire>Michelin Model XGV</part:tire>"
doc.xpath("//part:tire", "part" => "http://schwinn.com/").to_s # => "<part:tire>I'm a bicycle tire!</part:tire>"

doc.remove_namespaces!

doc.xpath("//tire").to_s # => "<tire>Michelin Model XGV</tire><tire>I'm a bicycle tire!</tire>"
doc.xpath("//part:tire", "part" => "http://general-motors.com/").to_s # => ""
doc.xpath("//part:tire", "part" => "http://schwinn.com/").to_s # => ""
