NSXMLParserErrorDomain while parsing an XML - iphone

Question

I am Getting a weird problem. I am making an App which should run on Both iOS 4 & 5.When i parse my XML in iOS 5 It is doing great and i am getting my output, but when i am Trying to do the same in iOS 4 ,i am getting this error "NSXMLParserErrorDomain error 31". in the
- (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError;
my XML is like this.. i need to parse the title tag within Item tag...
<item> <title> <![CDATA[ Cynical approach to tar my reputation: Army Chief on leaked letter ]]> </title> <link> <![CDATA[ ]]> </link> <guid isPermaLink="false"> <![CDATA[ ]]> </guid> </item> <item> <title> <![CDATA[ Major fire in scrap godown in suburban Mumbai ]]> </title> <link> <![CDATA[ ]]> </link> <guid isPermaLink="false"> <![CDATA[ ]]> </guid> </item>
My parsing code id this :-
-(void)parseBN{
NSString *URL=#"My XML's URL";
// convert the path to a proper NSURL
NSURL *xmlURL = [NSURL URLWithString:URL];
CTNetworking *request= [CTNetworking requestWithUrl:xmlURL];
[request setDelegate:self];
[request setDidFinishSelector:#selector(startParse:)];
[request startRequest];
}
-(void)startParse:(CTNetworking*)response{
if (response.responseStatusCode == 200 && rssParser == nil) {
[stories removeAllObjects];
NSString *myStr = [[NSString alloc] initWithData:[response responseData] encoding:NSWindowsCP1251StringEncoding];
myStr = [myStr stringByReplacingOccurrencesOfString:#"encoding=\"windows-1251\"" withString:#""];
NSData* aData = [myStr dataUsingEncoding:NSASCIIStringEncoding];
// NSXMLParser *parser = [[NSXMLParser alloc] initWithData:aData];
rssParser = [[NSXMLParser alloc] initWithData:aData];
// rssParser = [[NSXMLParser alloc] initWithData:[response responseData]];
// Set self as the delegate of the parser so that it will receive the parser delegate methods callbacks.
[rssParser setDelegate:self];
// Depending on the XML document you're parsing
[rssParser setShouldProcessNamespaces:NO];
[rssParser setShouldReportNamespacePrefixes:NO];
[rssParser setShouldResolveExternalEntities:NO];
[rssParser parse];
}
}
- (void)parserDidStartDocument:(NSXMLParser *)parser{
}
- (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError {
NSString * errorString = [NSString stringWithFormat:#"Unable to download story feed from web site (Error code %i )", [parseError code]];
NSLog(#"error parsing XML: %#", errorString);
UIAlertView * errorAlert = [[UIAlertView alloc] initWithTitle:#"Error loading content" message:errorString delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[errorAlert show];
}
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{
It is not coming here.. so didn't paste the Inside code
}
I searched in google for this error and everybody saying this error comes because of Unknown Encoding.. so i tried with "NSWindowsCP1251StringEncoding" also instead of default Encoding.
Any Help will be Appreciated.

Answer 1

Finally i got it working...
NSString *myStr = [[[NSString alloc] initWithData:[response responseData] encoding:NSWindowsCP1251StringEncoding] autorelease];
myStr = [myStr stringByReplacingOccurrencesOfString:#"encoding=\"windows-1251\"" withString:#""];
myStr = [myStr stringByReplacingOccurrencesOfString:#"US-ASCII" withString:#"UTF-8"];
NSData* aData = [myStr dataUsingEncoding:NSASCIIStringEncoding];
rssParser = [[NSXMLParser alloc] initWithData:aData];
[rssParser setDelegate:self];
[rssParser setShouldProcessNamespaces:NO];
[rssParser setShouldReportNamespacePrefixes:NO];
[rssParser setShouldResolveExternalEntities:NO];
[rssParser parse];
Changed the Encoding type through NSString :)
