A very simple question as I don't have much understanding of regex searching. How do I go about using a regular expression to insert a string at the beginning of end of a line? At the moment I can only replace the character at the beginning or end of a line. So for instance this string:

data:image/x-icon;base64,AAABAAEAICAAAAAAAAAoCQAAFgAAACgAAAAgAAA

becomes

'data:image/x-icon;base64,AAABAAEAICAAAAAAAAAoCQAAFgAAACgAAAAgAAA'+
