Below you find a complete example how to use a RestTemplate to exchange XML documents and receive a HTML response:

import static org.hamcrest.Matchers.is;
import static org.junit.Assert.assertThat;
import static org.springframework.test.web.client.match.MockRestRequestMatchers.header;
import static org.springframework.test.web.client.match.MockRestRequestMatchers.content;
import static org.springframework.test.web.client.match.MockRestRequestMatchers.method;
import static org.springframework.test.web.client.match.MockRestRequestMatchers.requestTo;
import static org.springframework.test.web.client.response.MockRestResponseCreators.withSuccess;

import org.junit.Test;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.test.web.client.MockRestServiceServer;
import org.springframework.web.client.RestTemplate;
import org.w3c.dom.Document;
import org.xml.sax.InputSource;

import java.io.StringReader;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;

public class XmlTest {

    @Test
    public void test() throws Exception {
        RestTemplate restTemplate = new RestTemplate();
        MockRestServiceServer mockServer = MockRestServiceServer.createServer(restTemplate);
        String htmlString = "
response
";
        String xmlString = "123";

        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        Document document = builder.parse(new InputSource(new StringReader(xmlString)));

        mockServer.expect(requestTo("http://localhost:8080/xml/availability"))
                .andExpect(method(HttpMethod.POST))
                .andExpect(content().string(is(xmlString)))
                .andExpect(header("header", "value"))
                .andRespond(withSuccess("
response
", MediaType.TEXT_HTML));

        HttpHeaders headers = new HttpHeaders();
        headers.add("header", "value");
        HttpEntity request = new HttpEntity<>(document, headers);

        final ResponseEntity response = restTemplate.postForEntity("http://localhost:8080/xml/availability", request, String.class);

        assertThat(response.getBody(), is(htmlString));
        mockServer.verify();
    }
