iPhone remove

Question

I am reading a xml and finaly just need to remove the CDATA Infos in my results

For example: I get:

 "<![CDATA[iPhone 4-Rückgaberecht: Deutsche Telekom kulant]]>"

just need "iPhone 4-Rückgaberecht: Deutsche Telekom kulant"

thx chris

Edit to your answers: I am not using NSXMLParser (thats the reason I make my own parser)

Found some suggestions with:

- (NSString *)stringByDecodingXMLEntities;
but dont know how to implement. I always get
> YourController may not respond to '-stringByDecodingXMLEntities" <

I don't know anything about the iPhone, but the XML parser **should** remove the CDATA sections for you. Shame on him/her/it if he/she/it doesn't. — MvanGeest, Jul 29 '10 at 09:23
I'd seriously recommend using NSXMLParser. XML is much more complicated than most people think. Rolling your own parser is a recipe for bugs and incompatibilities. — bobince, Jul 29 '10 at 10:04

Ok, i solved it with that:

 NSMutableString* resultString;


- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)s {
   resultString = [[NSMutableString alloc] init];
    [resultString appendString:s];
}

- (NSString*)convertEntiesInString:(NSString*)s {
    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;
}

call: myConvertedString = [self convertEntiesInString:myOriginalString];

use

(void)parser:(NSXMLParser *)parser foundCDATA:(NSData *)CDATABlock

method instead of

(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string

thats it

you could try a regex

replace <!\[CDATA\[(.*)\]\]> with $1

If you already have the String in String format with the you can remove it like so:

//Declare what you wish to remove
NSString * suffixTorRemove = @"<![CDATA[";
NSString * prefixToRemove = @"]]>";

//Now create a new string which uses your existing string and removes the declared occurrences above
NSString * newString = [yourString stringByReplacingOccurrencesOfString:suffixTorRemove withString:@""];
//Now the first part has changed, time to remove the second part
NSString * newString2 = [newString stringByReplacingOccurrencesOfString:prefixTorRemove withString:@""];

Quick and simple :-)
