copied!<p>It appears the CDATA contents in the <code><fact></code> tags is being returned incrementally over multiple call backs in <code>parser:foundCharacters</code>. In you class where you are conforming to NSXMLParserDelegate try building up the CDATA by appending it to an NSMutableString instance, like so:</p> <p>(Note: here _currentElement is an NSString property and _factString is an NSMutableString property)</p> <pre><code>- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict { self.currentElement = elementName; if ([_currentElement isEqualToString:@"fact"]) { // Make a new mutable string to store the fact string self.factString = [NSMutableString string]; } } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if ([elementName isEqualToString:@"fact"]) { // If fact string starts with CDATA tags then just get the CDATA without the tags NSString *prefix = @"<![CDATA["; if ([_factString hasPrefix:prefix]) { NSString *cdataString = [_factString substringWithRange:NSMakeRange((prefix.length+1), _factString.length - 3 -(prefix.length+1))]; // Do stuff with CDATA here... NSLog(@"%@", cdataString); // No longer need the fact string so make a new one ready for next XML CDATA self.factString = [NSMutableString string]; } } } - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if ([_currentElement isEqualToString:@"fact"]) { // If we are at a fact element, append the string // CDATA is returned to this method in more than one go, so build the string up over time [_factString appendString:string]; } } </code></pre>
