Divide and conquer just break up your input into separate interfaces.
something like
String output = getShowOutput();
int index = output.indexOf( "interface:" );
int secondIndex = output.indexOf( "interface:", index );
String firstInterface = output.substring( index, secondIndex );
then do the match on firstInterface and get the values and repeat the process
to get the next interface.
kind regards
