Read response with Nokogiri from a SOAP call with Savon - ruby-on-rails

Question

I have make a soap-call with Savon. This works fine and give the
following response:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://
schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<GetTop10Response xmlns="http://www.kirupafx.com">
<GetTop10Result>
<string>string</string>
<string>string</string>
</GetTop10Result>
</GetTop10Response>
</soap:Body>
</soap:Envelope>
Now I want to take all of the string elements out of the response. But
I can't get it to work.
def query(params=nil)
client = Savon::Client.new do
wsdl.document = "http://www.kirupafx.com/WebService/TopMovies.asmx?wsdl"
end
response = client.request :get_top10
if response.success?
xml = Nokogiri::XML(response.to_xml)
print "Until here oké!"
xml.search('//GetTop10Result').each do |result|
print "How are you Ruby?"
#result[result.at('string').inner_text] = result.at('string').inner_text
end
else
raise "Error!"
end
But he never prints my beautiful "How are you Ruby?" Can somebody help
me? What I'm doing wrong?

Answer 1

You could to this but this isnt the best way to deal with problems like this! You might have experience using Nokogiri and XML but its easier to use .to_hash like this.
def query
client = Savon::Client.new do
wsdl.document = "http://www.kirupafx.com/WebService/TopMovies.asmx?wsdl"
end
response = client.request(:get_top10)
response.to_hash[:get_top10_response][:get_top10_result] if response.success?
false
end

Answer 2

Thanks for both reactions! I figured out. Here is my code:
# Prepare SOAP-request
client = Savon::Client.new do
wsdl.document = "http://www.kirupafx.com/WebService/TopMovies.asmx?wsdl"
end
# Execute SOAP-request
response = client.request :get_top10
if response.success?
names = Array.new(10)
index = 0
hash = response.to_hash[:get_top10_response][:get_top10_result][:string]
hash.each do |value|
names[index] = value
index += 1
end
#result = {
"0"=>{"name"=>"#{names.at(0)}"},
"1"=>{"name"=>"#{names.at(1)}"},
"2"=>{"name"=>"#{names.at(2)}"},
"3"=>{"name"=>"#{names.at(3)}"},
"4"=>{"name"=>"#{names.at(4)}"},
"5"=>{"name"=>"#{names.at(5)}"},
"6"=>{"name"=>"#{names.at(6)}"},
"7"=>{"name"=>"#{names.at(7)}"},
"8"=>{"name"=>"#{names.at(8)}"},
"9"=>{"name"=>"#{names.at(9)}"}
}
else
raise "Error occurred during the request to the top 10 movies!"
end
