Why does SOAPUI return bad request? - soap

Question

I have created a soapui project to test this wsdl
When sending this request
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:x/="http://www.w3schools.com/xml/">
<soapenv:Header/>
<soapenv:Body>
<x/:CelsiusToFahrenheit>
<!--Optional:-->
<x/:Celsius>30</x/:Celsius>
</x/:CelsiusToFahrenheit>
</soapenv:Body>
I get bad request in raw response
HTTP/1.1 400 Bad Request
Cache-Control: private,public
Content-Type: text/xml; charset=utf-8
Date: Sun, 28 Feb 2016 17:33:28 GMT
Server: Microsoft-IIS/7.5
X-AspNet-Version: 4.0.30319
X-Powered-By: ASP.NET
Content-Length: 0

Answer 1

The error is so trivial due to the special character in the namespace (x/), which can be found by Validating the request( clicking keys 'Alt+v` in the request editor)
Could not figure it out that why such special character is coming when soapUI generates the request
What should be done in order to make the request valid?
Please change the request to below(replaced x/ to x):
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:x="http://www.w3schools.com/xml/">
<soapenv:Header/>
<soapenv:Body>
<x:CelsiusToFahrenheit>
<x:Celsius>30</x:Celsius>
</x:CelsiusToFahrenheit>
</soapenv:Body>
</soapenv:Envelope>
Below is the screen shot of successful response upon changing the request as above.
