RSS Reader

[starwarsdevwookie59]

I've followed the popular tutorial on the apple blog on how to create a simple RSS reader, and was able to do so. I also made an "advanced" reader using

iPhone SDK Tutorial: Building an Advanced RSS reader using TouchXML (Part 1) | dBlog.com.au

However, neither of these programs can open up the RSS that I want them to. I understand the code when I read it, but I couldn't tell you what the problem is. Does anyone know what could be keeping it from opening the feed?

And I'm what you would call a beginner with this stuff, so there are no stupid replies.
Any help would be much appreciated,
thanks.

You have to tell us what feed your are trying to open.

Right, sorry.

feed://www.medicalmommas.com/profiles/blog/feed?promoted=1&xn_auth=no

It's for a project I've sort of been hired to do.

Are you getting any errors that we need to be aware of?

[starwarsdevwookie59]

Sorry again, I'm not thinking. There are no errors on the build, two warnings on the simple reader though. Then when I try to open it on the simple one it pops up with error five. The other reader just doesn't load anything in the cells.

Thanks again for any help.


And sorry about that...

I'm assuming error 5 is from the xml parser. Did you look up what error 5 is?

  NSXMLParserPrematureDocumentEndError = 5,


NSXMLParserPrematureDocumentEndError - The document ended unexpectedly.

[starwarsdevwookie59]

Right, I did look that up. So what should I do to fix it?

Thanks again for your help

Also-I downloaded ThumStruck, very impressive.

When I get that error, it most likely means that the XML is not formatted correctly, either a tag didnt get closed when it should have something like that..

In order to determine exactly where in the feed the problem occurs, I like to print out the name of the elements in the didStartElement and didEndElement parser delegate methods.

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict
{
     NSLog(@"<%@>", elementName);

// do other stuff
}

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
    NSLog(@"</%@>", elementName);
}

Now you should be able to see what element you were on when the error gets thrown. Just look @ the console output.

Nice. Good idea. I put the code in just like you put it, along with the other stuff in the function. But all that's coming up in the console is:

[Session started at 2009-06-20 18:33:20 -0400.]
2009-06-20 18:33:22.696 TAB RSS reader[12695:20b] error parsing XML: Unable to download story feed from web site (Error code 5 )

I can't thank you enough for helping me with this. I appreciate your helpful replies.

This probably means that it is trying to parse the file before it has had a chance to download any part of it yet.
