Simple XML Serializer unable to satisfy element

Question

I'm new to this Simple XML serializer and i want to parse the IGN news feed. The problem is that i get the following error:

Unable to satisfy @org.simpleframework.xml.Element(data=true, name=description, required=true, type=void) on field 'description' private java.lang.String org.android.entities.Channel.description for class org.android.entities.Channel at line 2

The xml look something like this:

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" media="screen" href="/~d/styles/rss2full.xsl"?><?xml-stylesheet type="text/css" media="screen" href="http://feeds.ign.com/~d/styles/itemcontent.css"?><rss xmlns:geo="http://www.w3.org/2003/01/geo/wgs84_pos#" xmlns:content="http://purl.org/rss/1.0/modules/content/" xmlns:media="http://search.yahoo.com/mrss/" xmlns:yt="http://gdata.youtube.com/schemas/2007" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:feedburner="http://rssnamespace.org/feedburner/ext/1.0" version="2.0">

Which means we have this one last review for you before yet another Young Justice hiatus begins…

So the parser says that the problem is in the "description" tag that is in the "channel" tag. And i really don't know what I'm doing wrong. Here is my Channel class:

package org.android.entities;

import java.io.Serializable;
import java.util.List;

import org.simpleframework.xml.Element;
import org.simpleframework.xml.ElementList;
import org.simpleframework.xml.Root;


    @Root public class Channel implements Serializable{


    /**
     * 
     */
    private static final long serialVersionUID = -6866019353714061968L;

    public Channel() {
        // TODO Auto-generated constructor stub
    }

    @Element
    private String title;

    @Element
    private String description;

    @Element
    private String link;

    @Element
    private String pubDate;

    @ElementList
    private List<Item> item;

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public String getLink() {
        return link;
    }

    public void setLink(String link) {
        this.link = link;
    }

    public String getPubDate() {
        return pubDate;
    }

    public void setPubDate(String pubDate) {
        this.pubDate = pubDate;
    }

    public List<Item> getNews() {
        return item;
    }

    public void setNews(List<Item> news) {
        this.item = news;
    }
}

And this is the method in that I'm executing the deserialization:

private void getFromCache() {
        Serializer serializer = new Persister();
        try {
            data = serializer.read(Channel.class, destinationFile, false);
        } catch (Exception e) {
            Log.e(TAG, e.getMessage());
            e.printStackTrace();
        }
    }

Answer 1

Now to answer my own question. I was playing a little bit and the problem is like Nathan Villaescusa suggested in ignoring the RSS tag. Look like you have to make a class (In this case the RSS class, and it has only one Element called Channel) that has to be the root element of the xml file. I didn't find a solution where i can ignore that element and jump straight to the channel tag. Thanks for your help :)
