Your example would look something like this:<BR/><BR/>require 'Hpricot'<BR/><BR/>doc = HPricot(open('po.xml'))<BR/>sum = 0<BR/>doc.search('item') do |item|<BR/> puts item.search('productname').first<BR/> sum += item.search('usprice').first.to_f * item.search('quantity').first.to_i<BR/>end<BR/><BR/>If you instead had tags like<BR/><item partNum="xxx" price="39.99" qty="2" /> you would access that like this:<BR/><BR/>doc.search('item') do |item|<BR/> puts item['productname']<BR/> sum += item['usprice'].to_f * item['quantity'].to_i<BR/>end I did some XML processing recently with HPricot in ruby. Your example would look something like this:

require ‘Hpricot’

doc = HPricot(open(‘po.xml’))
sum = 0
doc.search(‘item’) do |item|
puts item.search(‘productname’).first
sum += item.search(‘usprice’).first.to_f * item.search(‘quantity’).first.to_i
end

If you instead had tags like
<item partNum=”xxx” price=”39.99″ qty=”2″ /> you would access that like this:

doc.search(‘item’) do |item|
puts item['productname']
sum += item['usprice'].to_f * item['quantity'].to_i
end
