Here are two small examples based on your original XML:

irb(main):001:0> require 'rexml/document'
=> true
irb(main):002:0> file = File.new('sample.xml')
=> #<File:sample.xml>
irb(main):003:0> doc = REXML::Document.new(file)
=> <UNDEFINED> ... </>
irb(main):004:0> root = doc.root
=> <env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'> ... </>

irb(main):005:0> root.each_element('//ns2:sourcingChannel') do |sC|
irb(main):006:1*   puts sC.elements['name'].text
irb(main):007:1> end

irb(main):008:0> body = root.elements['env:Body']
=> <env:Body> ... </>
irb(main):009:0> acr = body.elements['ns2:getActiveChannelsResponse']
=> <ns2:getActiveChannelsResponse xmlns:ns2='http://ws.mrted.com/'> ... </>
irb(main):010:0> acr.elements.each do |sC|
irb(main):011:1*   puts sC.elements['name'].text
irb(main):012:1> end

I usually use something like the first way: each_element with an XPath
to pull out the "record" nodes for processing.
