    copied!<p>I have following code - methods to read xml files. But it works very slow for me. Isn't there any sufficient way to fetch &amp; read data faster.</p> <pre><code>if(connectionRemaining) { [self LoadingPopUp]; NSURL *tmpURl=[NSURL URLWithString:[NSString stringWithFormat:@"%@getcategory.php",[iGolfAppDelegate getServerPath]]]; NSMutableURLRequest *theRequest=[NSMutableURLRequest requestWithURL:tmpURl]; NSURLConnection *conn=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if(conn) myWebData=[[NSMutableData data] retain]; connectionRemaining=NO; } -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { [myWebData setLength: 0]; } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [myWebData appendData:data]; } -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { [connection release]; } -(void)connectionDidFinishLoading:(NSURLConnection *)connection { // NSString *theXML = [[NSString alloc] initWithBytes: [myWebData mutableBytes] length:[myWebData length] encoding:NSUTF8StringEncoding]; // NSLog(@"%@",theXML);[theXML release]; if( myXMLParser ) [myXMLParser release]; myXMLParser = [[NSXMLParser alloc] initWithData: myWebData]; [myXMLParser setDelegate: self]; [myXMLParser setShouldResolveExternalEntities: YES]; [myXMLParser parse];[connection release];[myWebData release]; } #pragma mark #pragma mark XMLParsing Methods -(void)parser:(NSXMLParser*)parser didStartElement:(NSString*)elementName namespaceURI:(NSString*)namespaceURI qualifiedName:(NSString*)qualifiedName attributes:(NSDictionary*)attributeDict { if([elementName isEqualToString:@"category"]) categoryArray=[[NSMutableArray alloc]init]; else if([elementName isEqualToString:@"Prop_Category"]) aCategory=[[Category alloc] init]; } -(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*)qualifiedName { if([elementName isEqualToString:@"category"]) { [LoadingAlert dismissWithClickedButtonIndex:0 animated:YES]; [LoadingAlert release];[self categoryPickerDiplay]; return; } else if([elementName isEqualToString:@"Prop_Category"]) { [categoryArray addObject:aCategory];[aCategory release];aCategory=nil; } else{ [aCategory setValue:currentElementValue forKey:elementName]; [currentElementValue release];currentElementValue=nil; } </code></pre> <p>}</p> <p>Let me clarify my question again.</p> <p>I have observed that this way of reading xml is not sufficient. By using this way iPhone loads data very slowly. Because, iphone will read &amp; compare each tag every time.</p> <p>I want some faster XML Loading &amp; Parsing.</p> <p>Thanks in advance for sharing your knowledge with me</p>
