Question

I’m parsing this line:

<type>branch</type>

with this code in didEndElement

if ([elementName isEqualToString:@"type"]) {

        [currentBranchDictionary setValue:currentText forKey:currentElementName];

    }

When I test the value in the type key, it does not contain branch but instead it contains branch\n. Here is the test I’m performing:

    if ([[currentBranchDictionary valueForKey:@"type"] isEqualToString:@"branch"]) {
        NSLog(@"no new-line");
    } else if ([[currentBranchDictionary valueForKey:@"type"] isEqualToString:@"branch\n"]) {
        NSLog(@"new-line");
    }

this returns the “new-line” output

Here’s the foundCharacters method:

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
    [currentText appendString:string];
}

I don’t understand where the carriage return is being added, can anyone help?

I suspect your XML contains carriage returns (“\r”) that aren’t being displayed by your editor. The XML specification requires these to be translated to line feeds (“\n”) prior to reporting the result to your application:

Can you verify the contents of your XML file? What is the output from the xxd command? Here’s the output from a file I created. Note the extra 0d character:

0000000: 3c74 7970 653e 6272 616e 6368 0d3c 2f74  <type>branch.</t
0000010: 7970 653e                                ype>
