To post XML data to the server, you need to make an HTTP POST request, include the XML in the body of the request message, and set the correct MIME type for the XML. The correct MIME type for XML is application/xml. In this post XML example, the Content-Type: application/xml request header specifies the resource's media type as XML. The Accept: application/xml request header tells the server that the client is expecting XML, and the Content-Type: application/xml response header indicates that the server returned XML. Click Send to execute the POST XML request online and see the results.
XML is an eXtensible Markup Language. It was designed to be a language with a simple formal syntax that makes it easy to create and manipulate documents by both programs and people, emphasizing its use on the Internet. XML is called extensible because it does not fix the markup used in documents: you can create markup according to the needs of a specific area, limited only by the syntax rules of the XML language. Physically, an XML document comprises entities, each of which can refer to a different entity. Logically, an XML document consists of comments, declarations, elements, and processing instructions. All of this in the document is structured using XML markup.
POST is one of the most commonly used HTTP methods. The POST request method is used to upload files and images to the server, submit web forms, or send any data to the server, including XML and JSON. The post data is included in the body of the POST message. The POST request header fields indicate the data type in the POST message, for example, Content-Type: application/xml for XML. The type and size of POST data is not limited.
To get an XML from the server, you need to send an HTTP GET request and include the Accept: application/xml header in your request. The Accept header tells the server that your client is expecting XML. Without this header, the server may return data in a different format. For example, if the server can process both XML and JSON on the same API endpoint, setting the Accept request header to application/xml will tell the server that the client is expecting XML and the server will provide the data in XML rather than JSON format.
