I have developed one application to fetch RSS feed. I am getting this error code 5 for some URLs where as som others are working fine.
I know this error means the xml is invalid. But for my app, I have not written any xml files by my own.
Please tell me the probable reasons for this and let me know the solution

Please check your library class for Rss feed parsing. Use standard library class, change the the code accordingly.

I'm following a tutorial and it's working fine but if I wanted to parse 2 RSS feeds it seems to overwrite one array instead of saving them in the respective arrays.
This is in my delegate:
NSURL *url2 = [[NSURL alloc] initWithString:#"myRSSFEED1"];
NSXMLParser *xmlParser1 = [[NSXMLParser alloc] initWithContentsOfURL:url2];
//Initialize the delegate.
XMLParser1 *parser1 = [[XMLParser1 alloc] initXMLParser];
//Set delegate
[xmlParser1 setDelegate:parser1];
//Start parsing the XML file.
BOOL successs = [xmlParser1 parse];
if(successs)
NSLog(#"No Errors");
else
NSLog(#"Error Error Error!!!");
//VIDS
NSURL *url = [[NSURL alloc] initWithString:#"MYRSSFEED2"];
NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithContentsOfURL:url];
//Initialize the delegate.
XMLParser *parser = [[XMLParser alloc] initXMLParser];
//Set delegate
[xmlParser setDelegate:parser];
//Start parsing the XML file.
BOOL success = [xmlParser parse];
if(success)
NSLog(#"No Errors");
else
NSLog(#"Error Error Error!!!");
that parses feed 1, allocates it to the array then parses 2 and seems to overwrite the first insteaf of using the second array that are defined as
#synthesize pics;
#synthesize books;
And saved in my XMLParser & XMLParser1
I can't figure out how to stop it from overwriting.
Here is my XMLParsers too:
- (void)parsers:(NSXMLParser *)parsers didStartElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName
attributes:(NSDictionary *)attributeDict {
if([elementName isEqualToString:#"Books"]) {
//Initialize the array.
appDelegate2.pics = [[NSMutableArray alloc] init];
}
else if([elementName isEqualToString:#"Book"]) {
//Initialize the book.
apics = [[BookPhoto alloc] init];
//Extract the attribute here.
apics.bookID = [[attributeDict objectForKey:#"id"] integerValue];
NSLog(#"Reading HAVid value :%i", apics.bookID);
}
NSLog(#"Processing Element: %#", elementName);
}
- (void)parsers:(NSXMLParser *)parsers foundCharacters:(NSString *)string {
if(!currentElementValue)
currentElementValue = [[NSMutableString alloc] initWithString:string];
else
[currentElementValue appendString:string];
NSLog(#"Processing Value: %#", currentElementValue);
}
- (void)parsers:(NSXMLParser *)parsers didEndElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
if([elementName isEqualToString:#"Books"])
return;
//There is nothing to do if we encounter the Books element here.
//If we encounter the Book element howevere, we want to add the book object to the array
// and release the object.
if([elementName isEqualToString:#"Book"]) {
[appDelegate2.pics addObject:apics];
[apics release];
apics = nil;
}
else
[apics setValue:currentElementValue forKey:elementName];
[currentElementValue release];
currentElementValue = nil;
}
And my XMLParser.m
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName
attributes:(NSDictionary *)attributeDict {
if([elementName isEqualToString:#"Books"]) {
//Initialize the array.
appDelegate.books = [[NSMutableArray alloc] init];
}
else if([elementName isEqualToString:#"Book"]) {
//Initialize the book.
aBook = [[Book alloc] init];
//Extract the attribute here.
aBook.bookID = [[attributeDict objectForKey:#"id"] integerValue];
NSLog(#"Reading id value :%i", aBook.bookID);
}
NSLog(#"Processing Element: %#", elementName);
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
if(!currentElementValue)
currentElementValue = [[NSMutableString alloc] initWithString:string];
else
[currentElementValue appendString:string];
NSLog(#"Processing Value: %#", currentElementValue);
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
if([elementName isEqualToString:#"Books"])
return;
//There is nothing to do if we encounter the Books element here.
//If we encounter the Book element howevere, we want to add the book object to the array
// and release the object.
if([elementName isEqualToString:#"Book"]) {
[appDelegate.books addObject:aBook];
[aBook release];
aBook = nil;
}
else
[aBook setValue:currentElementValue forKey:elementName];
[currentElementValue release];
currentElementValue = nil;
}
Any help on this would be brilliant,
I suggest putting a breakpoint at the point where the array is not getting loaded, and seeing if (1) it even gets called, and (2), whether it is saving the data into the array at all.
my bad
seems i had extra s's in parser:
- (void)parsers:(NSXMLParser *)parsers foundCharacters:(NSString *)string {
if(!currentElementValue)
currentElementValue = [[NSMutableString alloc] initWithString:string];
else
[currentElementValue appendString:string];
NSLog(#"Processing Value: %#", currentElementValue);
}
should have been:
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
if(!currentElementValue)
currentElementValue = [[NSMutableString alloc] initWithString:string];
else
[currentElementValue appendString:string];
NSLog(#"Processing Value: %#", currentElementValue);
}
cheers for the help tho
i try to parse within my iPhone SDK 4
http://de.news.search.yahoo.com/news/rss?p=iphone&ei=UTF-8&fl=0&x=wrt
there are some german umlaute
<description><![CDATA[Mehr als die Hälfte der Belegschaft des weltweit größten]]></description>
As I read in another forum as long they are wrapped in CDATA it should be fine.
But in the moment the parser found the element "description"
he breaks with:
error parsing XML: Unable to download story feed from web site (Error code 9 ) http://de.news.search.yahoo.com/news/rss?p=iphone&ei=UTF-8&fl=0&x=wrt
The english feeds works fine !? So its something with this umlaute, but what can i do?

Perhaps look into -stringWithContentsOfURL:usedEncoding:error: to download the XML:
NSError *error = nil;
NSStringEncoding encoding;
NSString *xmlFeedStr = [NSString stringWithContentsOfURL:[NSURL URLWithString:#"http://de.news.search.yahoo.com/news/rss?p=iphone&ei=UTF-8&fl=0&x=wrt"] usedEncoding:&encoding error:&error];
NSXMLParser *rssParser = [[NSXMLParser alloc] initWithData:[xmlFeedStr dataUsingEncoding:encoding allowLossyConversion:YES]];
...
[rssParser release];
From the documentation:
NSXMLParserInvalidCharacterError = 9
Perhaps the document is not really encoded in UTF-8?
Now I solved it different. Wrote my own XML parser just simple for my needs and with the following routine, i found in some forum, i encode the xml string. Also I marked the answer above as 'accepted' as it lead me into the right direction.
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)s {
[resultString appendString:s];
}
- (NSString*)convertEntiesInString:(NSString*)s {
resultString = [[NSMutableString alloc] init];
if(s == nil) {
//NSLog(#"ERROR : Parameter string is nil");
}
NSString* xmlStr = [NSString stringWithFormat:#"<d>%#</d>", s];
NSData *data = [xmlStr dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSXMLParser* xmlParse = [[NSXMLParser alloc] initWithData:data];
[xmlParse setDelegate:self];
[xmlParse parse];
NSString* returnStr = [[NSString alloc] initWithFormat:#"%#",resultString];
return returnStr;
}
objectsResultStr = [self convertEntiesInString:orgString]];
I am trying to parse an RSS XML feed. I have figured out how to parse what's in the tags for the individual stories, but I cannot figure out how to get the name of the entire feed (for example "CNN's News Feed"). I think it's in and I've tried a ton of things but I can't figure it out. Below is part of my parsing code that I think what seemed like the most sense, but didn't work. Can anyone help?
Thanks!!

}
The feed name is always included in the name of title by " - " at the end. Now if you want to get the feed name you can do it like.
NSDictionary *feedDict = [feedArray objectAtIndex:indexPath.row];
UILabel *lbl = (UILabel *)[cell.contentView viewWithTag:1];
NSArray *tempArr = [[NSArray alloc] initWithArray:[[feedDict valueForKey:#"title"] componentsSeparatedByString:#" - "]];
[lbl setText:[tempArr objectAtIndex:0]];
So you will see the name of feed in the lable.
Hope this helps.
Thanks,

The feeds title lays outside items and channels so you should also trigger for a title in didStartElement. You also might need to make some logic to differentiate between titles within items and channels and the global title.
Let's have a try to fix it...(also noticed some possible memory leaks)

I've released an open source RSS/Atom Parser for iPhone and it makes reading and parsing web feeds extremely easy.
You can set it to read just the feed info (title, summary, etc) if you want. Checkout the documentation and play around with the demo app. Hope this helps!
I have made a simple rss reader. The app loads an xml atom file in an array.
Now I have added categories to my atom feed, which are first loaded in the array
What is the best way to add drill down functionality programmatically.
Now only the categories are loaded into the array and displayed.
This is the implementation code

Apple provides a good sample app for demonstrating a drill-down tableview:
SimpleDrillDown
Write a generic UITableViewController subclass that takes an array of values. Then, when the user taps on a row, get the array of posts associated with the selected category and pass that to a new view controller. Then, push the view controller onto the stack, using [[self navigationController] pushViewController:nextViewController animated:YES];.
I've just released an open source RSS/Atom Parser for iPhone and hopefully it might be of some use.
I'd love to hear your thoughts on it too!
I'm parsing an RSS feed with NSXMLParser and it's working fine for the title and other strings but one of the elements is an image thats like
<!CDATA <a href="http:image..etc>
How do I add that as my cell image in my table view? Would I define that as an image type?
This is what i'm using to do my parsing:
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{
//NSLog(#"found this element: %#", elementName);
currentElement = [elementName copy];
if ([elementName isEqualToString:#"item"]) {
// clear out our story item caches...
item = [[NSMutableDictionary alloc] init];
currentTitle = [[NSMutableString alloc] init];
currentDate = [ [NSMutableString alloc] init];
currentSummary = [[NSMutableString alloc] init];
currentLink = [[NSMutableString alloc] init];
}
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{
//NSLog(#"ended element: %#", elementName);
if ([elementName isEqualToString:#"item"]) {
// save values to an item, then store that item into the array...
[item setObject:currentTitle forKey:#"title"];
[item setObject:currentLink forKey:#"link"];
[item setObject:currentSummary forKey:#"description"];
[item setObject:currentDate forKey:#"date"];
[stories addObject:[item copy]];
NSLog(#"adding story: %#", currentTitle);
}
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{
//NSLog(#"found characters: %#", string);
// save the characters for the current item...
if ([currentElement isEqualToString:#"title"]) {
[currentTitle appendString:string];
} else if ([currentElement isEqualToString:#"link"]) {
[currentLink appendString:string];
} else if ([currentElement isEqualToString:#"description"]) {
[currentSummary appendString:string];
} else if ([currentElement isEqualToString:#"pubDate"]) {
[currentDate appendString:string];
}
}
You can use
- (void)parser:(NSXMLParser *)parser foundCDATA:(NSData *)CDATABlock
{
NSString *someString = [[NSString alloc] initWithData:CDATABlock encoding:NSUTF8StringEncoding];
}
The point of CDATA is that anything within it is not treated as part of the XML document.
So if you have tags in CDATA the parser will ignore them.
I'm guessing this CDATA is in the description element. So you'll need to extract the tags from the "description" element, either manually or via another instance of a parser.
