iPhone: Parsing multiple XMLs

[kshitija]

Hi

I am trying to parse multiple XMLs in the same view. I can parse the 1st XML but not the 2nd one. I have pasted my XML Parsing code.



-

(void)readXML:(NSString *)valueEntered{
	
	
	NSString *soapMessage = [NSString stringWithFormat:
							 @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
							 "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
							 "<soap:Body>\n"
							 "<GetCommonCodeByCatg xmlns=\"http://longbeach.gov/PDPropertyReg/Services/\">\n"
							 "<catg>%@</catg>\n"
							 "</GetCommonCodeByCatg>\n"
							 "</soap:Body>\n"
							 "</soap:Envelope>\n",valueEntered];
	NSLog(@"Soap Message%@",soapMessage);
	
	NSURL *url =[NSURL URLWithString:@"http://wwwbitdemo.longbeach.gov/PDPropertyReg/Services/CommonCode.asmx"];
	NSMutableURLRequest *theRequest =[NSMutableURLRequest requestWithURL:url];
	NSString *msgLength =[NSString stringWithFormat:@"%d",[soapMessage length]];
	
	[theRequest addValue:@"text/xml; charset =utf-8" forHTTPHeaderField:@"Content-Type"];
	[theRequest addValue:@"http://longbeach.gov/PDPropertyReg/Services/GetCommonCodeByCatg" forHTTPHeaderField:@"SOAPAction"];
	[theRequest addValue:msgLength forHTTPHeaderField:@"Content-Length"];
	[theRequest setHTTPMethod:@"POST"];
	[theRequest setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
	
	NSURLConnection *theConnection =[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
	
	if (theConnection) {
		
		
		webData = [[NSMutableData data]retain];
		
		
		
		
	}
	else {
		NSLog(@"The connection is null");
	}
	
}


-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{
	
	[webData setLength:0];
	
	
}


-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{
	NSLog(@"connection");
	
	
	
	[webData appendData:data];
	
	
	
	
}

-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{
	NSLog(@"Connection Error");
	[connection release];
	
	
	
	[webData release];
	
	
	
	
	
}

-(void)connectionDidFinishLoading:(NSURLConnection *)connection{
	
	NSLog(@"Done, Received bytes: %d",[webData length]);
	
	
	
	NSString *theXML =[[NSString alloc] initWithBytes:[webData mutableBytes]length:[webData length]encoding:NSUTF8StringEncoding];
	NSLog(@"XML value %@",theXML);
	[theXML release];
	
	if (xmlParser) {
		[xmlParser release];
	}
	
	
	xmlParser = [[NSXMLParser alloc]initWithData:webData];
	[xmlParser setDelegate:self];
	[xmlParser setShouldResolveExternalEntities:YES];
	[xmlParser parse];
	
	
	
	[connection release];
	[webData release];
	
	
	
	
}

- (void)parserDidStartDocument:(NSXMLParser *)parser{ 
	NSLog(@"found file and started parsing");
	
	
	propertyCategories = [[NSMutableArray alloc]init];
	
	

}


-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{
	
	
	
	if ([elementName isEqualToString:@"GetCommonCodeByCatgResponse"]) {
	}
	
	if ([elementName isEqualToString:@"SvcCommonCode"]) {
		
		
		
		
		aCategory =[[Category alloc]init];
		
		aCategory.CMCodeDesc = [attributeDict objectForKey:@"CMCodeDesc"];
		
		
		
		/*		
		 if ([recordResults isEqualToString:@"COLOR"]) {
		 
		 
		 bCategory =[[Category alloc]init];
		 
		 bCategory.CMCodeDesc = [attributeDict objectForKey:@"CMCodeDesc"];
		 NSLog(@"bCateg%@",bCategory);
		 }*/
		
		
		
		
	}
	
}

-(void)parser: (NSXMLParser *)parser foundCharacters:(NSString *)string{
	
	
	if (!currentElementValue) 
		currentElementValue =[[NSMutableString alloc]initWithString:string];
	else 
		[currentElementValue appendString:string];
	
	
}

-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{
	
	if ([elementName isEqualToString:@"GetCommonCodeByCatgResponse"]) {
		
		//[itemCategoryList reloadAllComponents];
		//inputValue =@"COLOR";
		//[self readXML:inputValue];
		//return;
	}
	
	if ([elementName isEqualToString:@"SvcCommonCode"]) {
		
		
		[propertyCategories addObject:aCategory.CMCodeDesc];
		[aCategory release];
		aCategory =nil;
		
		
		NSLog(@"Property%@",propertyCategories);
		
		
		
	}
	
	else 
		
		
		
		[aCategory setValue:currentElementValue forKey:elementName];
	
	
	
	
	[currentElementValue release];
	currentElementValue = nil;
	
}

And when you say you can't parse the xml what does it mean exactly?

Does the app crash, does it make no attempt at parsing, does it maybe parse some of it?

The 1st XML is parsed as expected and the data is obtained.
When a call to the 2nd XML is made, it just forms the soap message and the application terminates.

What error does it throw when it terminates?
