Try this:

	import std.regex;
	string extractSerial(string input) {
		auto m = input.match(`SerialNumber\s+(\S+)\s+`);
		if (m)
			return m.captures[1];
		else
			throw new Exception("Could not find serial number");
	}

	auto input = "SerialNumber    \r\r\n92716002xxxx \r\r\n\r\r\n";
	writeln(extractSerial(input)); // prints "92716002xxxx"

Hope this helps.
