Data of the web services in a RSS

Question

I only have the .wsdl and I want to put the data that the web services return in the RSS. And in a web page of SAP, I can only upload RSS, so I need put the information of the web services in the RSS

For example, I put the information manually(name and total value) in the fields <title> and <descripcion>, these data are extracted from the web services. But sometimes I don´t know how much information brings the web service. Also, I know that RSS is not to store information such as web services.

<?xml version="1.0" encoding="UTF-8" ?> 
<rss version="2.0">
<channel>
<title>Test RSS</title>
