#before_and_after(begin_delimeter, end_delimeter) ⇒ Object

– – Get the text [in between] this and that delimeter [exclusively]. – Exclusively means the returned text [does not] include either of – the matched delimeters (although an unmatched instance of [this] – delimeter may appear in the in-between text). – – ——————– – Multiple Delimiters – ——————– – – When multiple delimiters exist, the text returned is in between the – – [a] - first occurrence of [this] delimeter AND the – [b] - 1st occurrence of [that] delimeter [AFTER] the 1st delimiter – – Instances of [that] delimiter occurring before [this] are ignored. – The text could contain [this] delimeter instances but is guaranteed – not to contain a [that] delimeter. – – ———– – Parameters – ———– – – this_delimiter : begin delimeter (not included in returned string) – that_delimiter : end delimeter (not included in returned string) – – ———– – Exceptions – ———– – – An exception (error) will be thrown if – – => any nil (or empties) exist in the input parameters – => [this] delimeter does not appear in the in_string – => [that] delimeter does not appear after [this] one –
