From the docs: A Nokogiri::XML::Node may be treated similarly to a hash with regard to attributes
I want to prepend a regular hash attribute
my_hash = { 'my_key' => 'bar' }
my_hash['my_key'].insert 0, 'foo'
my_hash #=> {'my_key'=>'foobar'}This simply cannot be done with nokogiri
doc = Nokogiri::HTML('<img src="bar" />')
doc.xpath("//img").each { |img| img['src'].insert 0, 'foo' }
doc.to_html #=> "<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\" \"http://www.w3.org/TR/REC-html40/loose.dtd\">\n<html><body><img src=\"bar\"></body></html>\n"You can do this if you get(attribute) first, however
doc.xpath("//img").each { |img| _src = img['src']; img['src'] = _src.insert 0, 'foo' }
doc.to_html #=> "<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\" \"http://www.w3.org/TR/REC-html40/loose.dtd\">\n<html><body><img src=\"foobar\"></body></html>\n"
