How to replace a "&" in received XML

I am receiving a list of inventory from a web service and so far one item has a "&" in it which messes up my parser. So far I 开发者_高级运维have tried:

street = [street stringByReplacingOccurrencesOfString:@"&" withString:@"and"];

but that didn't seem to work.

In the XML file, replace the & with &

Maybe you'll try

street = [street stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
