Question

I have previosly saved a string to a .txt like this:

$text = "<div class='highlight'><div><p>".$date.".</p> <h1> ".$heading."</h1>".$textbox."</div></div>";

I now want to extract $date, $heading and $textbox from the txtfile back to variables, for the purpose of editing and I have no clue how to do this.

Can anyone help me?

You need to use a DOM parser to parse the HTML.

http://simplehtmldom.sourceforge.net/

Code posted from the above site.

$html = file_get_html('http://www.google.com/');

// Find all images
foreach($html->find('img') as $element)
       echo $element->src . '
';

// Find all links
foreach($html->find('a') as $element)
       echo $element->href . '
'; 

OR PHP’s DOM

$str = file_get_contents(“a.txt”);
   $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 . “
“;
