    copied!<p>After several tutorials I have read, I am trying to create my own class in order to retrieve xml results from PHP requests and use their element in my iOS app.</p> <p>So I have XMLParse.h</p> <pre><code>#import &lt;Foundation/Foundation.h&gt; @interface XMLParser : NSObject &lt;NSXMLParserDelegate&gt;{ NSString* url; NSXMLParser* parser; NSMutableString* element; } - (id) initXML: (NSString*)_url; @end </code></pre> <p>and the XMLParse.m</p> <pre><code>#import "XMLParser.h" @implementation XMLParser{ NSXMLParser* xmlParser; NSMutableArray* xmlOutputData; NSMutableString* xmlOutputNode; } - (id) initXML:(NSString *)_url{ NSLog(@"initXML\n"); url = _url; xmlParser = [[NSXMLParser alloc] initWithContentsOfURL:[NSURL URLWithString:url]]; [xmlParser setDelegate:self]; if ([xmlParser parse]) { printf("YES"); } else{ printf("NO"); } return self; } - (void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{ NSLog(@"Started Element %@", elementName); if ([elementName isEqualToString:@"root"]) { if (!xmlOutputData) { xmlOutputData = [[NSMutableArray alloc] init]; NSString* status = [attributeDict objectForKey:@"success"]; if ([status isEqualToString:@"TRUE"]) { return; } else{ printf("ERROR"); } } } } - (void) parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{ [xmlOutputNode appendString:[string stringByTrimmingCharactersInSet: [NSCharacterSet whitespaceAndNewlineCharacterSet]]]; } - (void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{ if ([elementName isEqualToString:@"username"]) { NSLog(@"%@", xmlOutputNode); } xmlOutputNode = [[NSMutableString alloc]init]; } @end </code></pre> <p>Finally from my MenuView.m I'm initialising an object of XMLParse class</p> <pre><code>XMLParser* newParser = [[XMLParser alloc] initXML:@"http://localhost/conquestOfLancaster/login.php?username=test&amp;password=1234"]; </code></pre> <p>and the output on screen it looks like,</p> <pre><code>2012-12-01 18:58:50.020 CoL[2363:c07] initXML 2012-12-01 18:58:50.030 CoL[2363:1b03] ADDRESPONSE - ADDING TO MEMORY ONLY: http://localhost/conquestOfLancaster/login.php?username=test&amp;password=1234 NO </code></pre> <p>I can't understand what I am missing and always the parse is FALSE. Can anyone help?</p> <p>UPDATE:</p> <p>The problem was that my result from PHP link was not a real XML output (has the structure and that confused me). Is my first try with PHP and that's the reason. I will search how you can generate an XML output from a PHP.</p> <p>Thanks in advance.</p>
