Android SimpleXML库用于XML解析

Question

I am parsing one long xml using SimpleXML library. Here is the Link of Long XML

http://ax.itunes.apple.com/WebObjects/MZStoreServices.woa/ws/RSS/topsongs/limit=10/xml

Now I want guidance regarding im:image tag

I have made the following POJO class

public class Image {
private int height;

public Image(@Attribute(name = "height") int height)
{
    this.height=height;
}
@Attribute(name = "height") 
public int getObjectHeight() {
    return height;
}
}

but this doesn't look me correct, because it will only deal with height...how to parse the content between these tags

<im:image height="170"> </im:image>

and my second question is what should be variable name in java ... because im:image is not allowed in java.

Please help me ASAP.

Thanks

Answer 1

first you need to add the namespace for the element

@Namespace(reference = "http://itunes.apple.com/rss", prefix = "im")
public class Image {
   @Element(name = "image ")
   private String image_url;

   @Attribute
   private int height;
}

Answer 2

The next code works fine

@Root(name = "feed")
static class Feed {
    @Element
    Image image;

}

@Root(name = "image")
static class Image {

    @Attribute(name = "height")
    int height;

    @Text
    String content;

}

@Test
public void testPrefixedTag() throws Exception {
    String xml = 
            "<feed xmlns:im=\"http://itunes.apple.com/rss\" xmlns=\"http://www.w3.org/2005/Atom\">" +
            "<im:image height=\"170\">Content</im:image>" +
            "</feed>";
    Serializer serializer = new Persister();
    Feed feed = serializer.read(Feed.class, xml);
}

So, if you have reference to im namespace in your root tag (xml by your link has one) you can just use name of the child tags without it (as image in our case).

For parsing content between tags you use @Text annotation.
