Parsing a simple XML node on iPhone

I wanted to parse some simple XML response from a server and I really wouldn't bother to use NSXMLParser or libxml2 as discussed here on stackoverflow. I get a single node and I just wanted to get the content. I ended up with this utility method:

+ (NSString *)xmlNodeContent:(NSData *)xmlData {
NSString *node = [[NSString alloc] initWithData:xmlData encoding:NSUTF8StringEncoding];
NSString *content = @"";
if([node length] > 0) {
int start = [node rangeOfString:@">"].location + 1;
int end = [node rangeOfString:@"<" options:NSBackwardsSearch].location;
content = [node substringWithRange:NSMakeRange(start, end - start)];
[node release];
return content;
