I am using Retrofit 2.1.0 and Retrofit SimpleXML Converter 2.1.0. I added simplexmlconverter to retrofit instance with addConverterFactory method.

My retrofit api client relevant code : RetrofitAPIClient
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(loggingInterceptor)
.build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.client(client)
.addConverterFactory(SimpleXmlConverterFactory.create())
.build();
apiService = retrofit.create(MyService.class);
ArticleResponse.java
import org.simpleframework.xml.Element;
import org.simpleframework.xml.ElementList;
import org.simpleframework.xml.Root;
import java.util.List;
@Root(name = "rss")
public class ArticleResponse {
@Element(name = "channel")
public Channel channel;
public class Channel {
@ElementList
public List<Article> articles;
}
}
Article.java
import org.simpleframework.xml.Attribute;
import org.simpleframework.xml.Element;
import org.simpleframework.xml.Text;
@Element(name = "item")
public class Article {
@Element(name = "title")
private String title;

Answer
Try with strict = false :
@Root(name = "rss", strict = false)
public class ArticleResponse {
@Element(name = "channel")
public Channel channel;
public class Channel {
@ElementList
public List<Article> articles;
}
}
