Solution for finding parse error:
- (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError
{
NSDictionary *userInfo = parseError.userInfo;
NSNumber *lineNumber = userInfo[#"NSXMLParserErrorLineNumber"];
NSNumber *errorColumn = userInfo[#"NSXMLParserErrorColumn"];
NSString *errorMessage = userInfo[#"NSXMLParserErrorMessage"];
NSLog(#"Error occured in line %# and column %#\nWith message: %#", lineNumber, errorColumn, errorMessage);
}
