PARSING XML WITH OBJECTIVE-C (IOS)

JANUARY 4, 2011

In order to parse XML into an NSDictionary to be used in my iOS project, I have found and implementedXMLReader created by Troy Brant.

The implementation is simple to use as you can see for yourself:

1 2 3 4 5 6 7 8

NSString *testXMLString = @"<items><item id=\"0001\" type=\"donut\"><name>Cake</name><ppu>0.55</ppu><batters><batter id=\"1001\">Regular</batter><batter id=\"1002\">Chocolate</batter><batter id=\"1003\">Blueberry</batter></batters><topping id=\"5001\">None</topping><topping id=\"5002\">Glazed</topping><topping id=\"5005\">Sugar</topping></item></items>"; // Parse the XML into a dictionary NSError *parseError = nil; NSDictionary *xmlDictionary = [XMLReader dictionaryForXMLString:testXMLString error:&parseError]; // Print the dictionary NSLog(@"%@", xmlDictionary);

For my project however, I needed to parse through some XML returned from a webservice, so I usedASIHTTPRequest, since I was already implementing it for my project.

Ultimately, my code ended up looking like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

NSURL *url = [NSURL URLWithString:@"http://www.someurl/response.xml"]; ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; [request startSynchronous]; NSError *error = [request error]; if (!error) { NSString *response = [request responseString]; // NSLog(@"%@", response); NSError *parseError = nil; NSDictionary *xmlDictionary = [XMLReader dictionaryForXMLString:response error:&parseError]; // Print the dictionary NSLog(@"%@", xmlDictionary); }
