PHP Parse HTML code

Answer


Answer

Best methods to parse HTML







How can I parse HTML code held in a PHP variable if it something like:



T1
Lorem ipsum.
T2
The quick red fox...
T3
... jumps over the lazy brown FROG!


I want to only get the text that's between the headings and I understand that it's not a good idea to use Regular Expressions.


Answer



Use PHP Document Object Model:




   $str = '
T1
Lorem ipsum.
T2
The quick red fox...
T3
... jumps over the lazy brown FROG';
   $DOM = new DOMDocument;
   $DOM->loadHTML($str);

   //get all H1
   $items = $DOM->getElementsByTagName('h1');

   //display all H1 text

   for ($i = 0; $i < $items->length; $i++)
        echo $items->item($i)->nodeValue . "
";
?>


This outputs as:



 T1
 T2
 T3





[EDIT]: After OP Clarification:



If you want the content like Lorem ipsum. etc, you can directly use this regex:



   $str = '
T1
Lorem ipsum.
T2
The quick red fox...
T3
... jumps over the lazy brown FROG';

   echo preg_replace("#.*?#", "", $str);
?>


this outputs:




Lorem ipsum.The quick red fox...... jumps over the lazy brown FROG
