Here is the code:

<?php
   ini_set('max_execution_time', 300);
   //error_reporting(0);
   $errmsg_arr = array();
   $errflag = false;

   function getState($string)
   {
     $ex = explode(" ",$string."  ");
     return $ex[1];
   }
   $xml = "";
   $xml .= '<?xml version="1.0" encoding="UTF-8" ?>';
   $xml .= '
     <tv generator-info-name="www.mysite.com/xmltv">';
   $baseUrl = file_get_contents('www.myscript.com/get-listing.php');

   $domdoc = new DOMDocument();
   $domdoc->strictErrorChecking = false;
   $domdoc->recover=true;
   $domdoc->loadHTML($baseUrl);
?>

For example, my HTML might look like:

<p id='categories'>Sports</p>

I'm trying to extract the following text:

Sports

So when I tried this:

$p = $domdoc->getElementById('categories')->getElementsByTagName('p')->item(0);

echo $p;

It will not extract the content from the id categories.

How can I do it?

For that html only, you can do it like this:

echo $domdoc->getElementById('categories')->nodeValue;

Output:

Sports

See it in action here.

Since you can't have a  tag inside  tag, DOMDocument kind goes crazy about it. Depending on the case, you could do a workaround like this:

$baseUrl = '
<p id="categories">
    <p>Sports</p>
</p>';

$baseUrl = str_replace('<p', '<div', $baseUrl);
$baseUrl = str_replace('<p>', '<div>', $baseUrl);
$baseUrl = str_replace('</p>', '</div>', $baseUrl);

$domdoc = new DOMDocument();
$domdoc->loadHTML($baseUrl);

echo $domdoc->getElementById('categories')->getElementsByTagName('div')->item(0)->nodeValue;

The output is the same as before.
