IV. Example of a SOAP Request

A. Structure of the SOAP Request

A typical SOAP request would look like this:

<?xml version="1.0"?>
        <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
            <soap:Body>
                <FahrenheitToCelsius xmlns="http://www.example.com/">
                    <Fahrenheit>100</Fahrenheit>
                </FahrenheitToCelsius>
            </soap:Body>
        </soap:Envelope>

B. Example Code Snippet

Here’s a code snippet in JavaScript that sends the SOAP request:

const soapRequest = async () => {
            const response = await fetch('http://www.example.com/tempconvert.asmx', {
                method: 'POST',
                headers: {'Content-Type': 'text/xml'},
                body: `<?xml version="1.0"?>
                       <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
                           <soap:Body>
                               <FahrenheitToCelsius xmlns="http://www.example.com/">
                                   <Fahrenheit>100</Fahrenheit>
                               </FahrenheitToCelsius>
                           </soap:Body>
                       </soap:Envelope>`
            });
            const data = await response.text();
            console.log(data);
        };

        soapRequest();

V. Example of a SOAP Response

A. Structure of the SOAP Response

A typical SOAP response would look like this:

<?xml version="1.0"?>
        <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
            <soap:Body>
                <FahrenheitToCelsiusResponse xmlns="http://www.example.com/">
                    <FahrenheitToCelsiusResult>37.7778</FahrenheitToCelsiusResult>
                </FahrenheitToCelsiusResponse>
            </soap:Body>
        </soap:Envelope>

B. Example Code Snippet

The following code snippet demonstrates how to handle the SOAP response in JavaScript:

const parseSOAPResponse = (xmlResponse) => {
            const parser = new DOMParser();
            const xmlDoc = parser.parseFromString(xmlResponse, "text/xml");
            const result = xmlDoc.getElementsByTagName("FahrenheitToCelsiusResult")[0].childNodes[0].nodeValue;
            console.log(`Converted Temperature: ${result}°C`);
        };
