If you Google around, I am sure you can find many sample PHP scripts that do most of what you want. This is very old technology and there is no need to reinvent the wheel parsing HTML data.

Neo, As I stated, still struggling with the terminology and concepts, so patience, I'm total newbie at using this technology, that's why I'm asking Qs as I don't even know where to focus, right now, to accomplish this.
Cheers!

LEARN ABOUT PHP

fgetss

FGETSS(3)								 1								 FGETSS(3)

fgetss - Gets line from file pointer and strip HTML tags

SYNOPSIS

       string fgetss (resource	$handle, [int  $length], [string  $allowable_tags])

DESCRIPTION

	Identical to fgets(3), except that fgetss(3) attempts to strip any NUL bytes, HTML and PHP tags from the text it reads.

PARAMETERS

	      o $handle
		-The  file  pointer must be valid, and must point to a file successfully opened by fopen(3) or fsockopen(3) (and not yet closed by
		fclose(3)).

	      o $length
		- Length of the data to be retrieved.

	      o $allowable_tags
		- You can use the optional third parameter to specify tags which should not be stripped.

RETURN VALUES

	Returns a string of up to $length - 1 bytes read from the file pointed to by $handle, with all HTML and PHP code stripped.

	If an error occurs, returns FALSE.

       Example #1

	      Reading a PHP file line-by-line

	      <?php
	      $str = <<<EOD
	      <html><body>
	       <p>Welcome! Today is the <?php echo(date('jS')); ?> of <?= date('F'); ?>.</p>
	      </body></html>
	      Text outside of the HTML block.
	      EOD;
	      file_put_contents('sample.php', $str);

	      $handle = @fopen("sample.php", "r");
	      if ($handle) {
		  while (!feof($handle)) {
		      $buffer = fgetss($handle, 4096);
		      echo $buffer;
		  }
		  fclose($handle);
	      }
	      ?>

	      The above example will output something similar to:

	      Welcome! Today is the  of .

	      Text outside of the HTML block.

NOTES

       Note

	      If PHP is not properly recognizing the line endings when reading files either on or created by a Macintosh  computer,  enabling  the
	      auto_detect_line_endings run-time configuration option may help resolve the problem.
