  1. POIssue with a collection of response elements using Savon
    text
    copied!<p>I am attempting to use Savon to communicate with a legacy web service using SOAP. I am having an issue with regards to how Savon constructs a hash out of the response envelope.</p> <pre><code>client = Savon.client("http://my-service-endpoint/?wsdl") response = client.request :my_soap_operation do soap.body do |xml| xml.in("test") end end response.to_hash[:my_soap_operation_response][:out].each do |a| puts "Return element: #{a}" puts "Name #{a[:name]}" puts "Type #{a[:type]}" puts "Code #{a[:code]}" end </code></pre> <p>end </p> <p>If the SOAP response contains more than 1 'out' element, such as this:</p> <pre><code>&lt;mySoapOperationResponse&gt; &lt;out&gt; &lt;code&gt;C1947944&lt;/code&gt; &lt;name&gt;Use&lt;/name&gt; &lt;type&gt;type 1&lt;/type&gt; &lt;/out&gt; &lt;out&gt; &lt;code&gt;C1947946&lt;/code&gt; &lt;name&gt;name 2&lt;/name&gt; &lt;type&gt;type 2&lt;/type&gt; &lt;/out&gt; &lt;out&gt; &lt;code&gt;C1947947&lt;/code&gt; &lt;name&gt;name 2&lt;/name&gt; &lt;type&gt;type 3&lt;/type&gt; &lt;/out&gt; &lt;/mySoapOperationResponse&gt; </code></pre> <p>The output is as expected:</p> <pre><code>Return element: {:code=&gt;"C1947944", :name=&gt;"Use", :type=&gt;"type 1"} Name Use Type type 1 Code C1947944 Return element: {:code=&gt;"C1947946", :name=&gt;"name 2", :type=&gt;"type 2"} Name name 2 Type type 2 Code C1947946 Return element: {:code=&gt;"C1947947", :name=&gt;"name 2", :type=&gt;"type 3"} Name name 2 Type type 3 Code C1947947 </code></pre> <p>However, if the SOAP response only contains a single 'out' element, such as this:</p> <pre><code>&lt;mySoapOperationResponse&gt; &lt;out&gt; &lt;code&gt;C1947944&lt;/code&gt; &lt;name&gt;name 1&lt;/name&gt; &lt;type&gt;type 1&lt;/type&gt; &lt;/out&gt; &lt;/mySoapOperationResponse&gt; </code></pre> <p>I see this in the console</p> <pre><code>Return element: [:code, "C1947944"] </code></pre> <p>... and then I get the error message</p> <pre><code>can't convert Symbol into Integer </code></pre> <p>It would appear as though the :name and :type elements are not present in the SOAP response, however I can see them via the response XML message.</p> <p>I am using Savon v1.2.0.</p> <p><strong>Addendum</strong></p> <p>I added the following code to try to further debug the issue:</p> <pre><code> response = client.request :my_soap_operation do soap.body do |xml| xml.in("test") end end pp response.to_hash response.to_hash[:my_soap_operation_response][:out].each do |a| pp a puts "Return element: #{a}" puts "Name #{a[:name]}" puts "Type #{a[:type]}" puts "Code #{a[:code]}" </code></pre> <p>And I can see the elements being pretty-printed in the response hash. Here is a snapshot of the console:</p> <pre><code>&lt;soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"&gt; &lt;soapenv:Body&gt; &lt;mySoapOperationResponse&gt; &lt;out&gt; &lt;code&gt;C1947944&lt;/code&gt; &lt;name&gt;name 1&lt;/name&gt; &lt;type&gt;type 1&lt;/type&gt; &lt;/out&gt; &lt;/mySoapOperationResponse&gt; &lt;/soapenv:Body&gt; &lt;/soapenv:Envelope&gt; {:my_soap_operation_response=&gt; {:out=&gt;{:code=&gt;"C1947944", :name=&gt;"name 1", :type=&gt;"type 1"}, :@xmlns=&gt;"http://namespace.removed.com/"}} [:code, "C1947944"] Return element: [:code, "C1947944"] </code></pre> <p>However it seems like inside the .each loop (looping over each 'out' element), only the first element can be accessed?</p>
