title: Basic regex expression
body: <p>I'd like to replace angle brackets and spaces in a string. For example <code>@"&lt; something &gt;"</code> goes to <code>@"something"</code>. I'm currently trying:</p>
  
  <pre><code>NSString *s1 = @"&lt; something &gt;";
  NSString *s2 =
  [s1 stringByReplacingOccurrencesOfString:@"[&lt;&gt; ]"
                                withString:@""
                                   options:NSRegularExpressionSearch
                                     range:NSMakeRange(0, s1.length)];
  </code></pre>
  
  <p>However I'm brand new to regular expressions and <code>@"[&lt;&gt; ]"</code> doesn't seem to work. What's the correct regular expression to use to remove angle brackets and spaces?</p>
