The grep line I gave earlier does the speaker.  Adjust it a bit to do %mor:
grep '%mor' my_original_file.cha > mymor.cha
Again, the file should have its lines straightened first using LONGTIER or Sed.

Sure, the more complicated your question, the more complicated your tools may 
have to be, and CLAN may do nearly everything you want out of the box, 
provided you get the switches right.  For your use-case, I would use the 
following 12-line PHP script:
===
 <?php

//Open a new file to write to.
$fp = fopen("mymor.txt", "w");

// Open the source file.
$lines=file("path/to/my/file.cha");
// Read through each line.
foreach ($lines as $line)
{
	// If it's a speaker line matching the speaker you want ...
	if (preg_match("/^\*HYW/", $line))
	{
		$getmor=1;  //  ... set a marker.
	}
	//  If it's a speaker line that doesn't match that speaker ...
	elseif (preg_match("/^\*[^(HYW)]/", $line))
	{
		$getmor=0;  // ... revert the marker.
	}
	
	// If it's a %mor line and the marker is set ...
	// (ie the last speaker was HYW) ...
	if (preg_match("/^%mor/", $line) and $getmor==1)
	{
		echo $line;  // ... show the line ...
		fwrite($fp, $line);  // ... write it to the new file ...
		$getmor=0;  // ... revert the marker.
	}
}

// Close the new file.
fclose($fp);

?>

Not everyone will want to do this, I know, but the benefit of using PHP (or 
grep, or Python, or R, or whatever) is that researchers can learn something 
they can re-use in other contexts, or where other tools fit in better with 
their workflow, or where CLAN, for all its versatility, can't produce what they 
need.

Hmm - I've always found XML harder to parse than text, but maybe that's just 
me! :-)
