Get the string between custom delimiters

Is there a nice easy function that could be used to get a sub string that lies in between two other sub strings in one big string. For example... get the text that lies in between "<title>" and "</title>" (without the quotes) in the code of a web page. I'm after a function like: string getstring_between_customdelimiters(string source, string open_delimiter, sting close_delimiter) Or something that could be easily be used in that manner. Case insensitive if possible! Thanks, Matt matthew.ralston@haltoncollege.ac.uk < www.mralston.co.uk />
