title: Selector placehoder for a single charcter
body: <p>I'm using a jQuery selector and I need to choose some elements based on the position of the characters. For example, I need to select those items that have the 3rd character as 'h' and 4th character as 'r'. From the below list, the selector should select the first two elements but not the third. </p>
