PHP Regex find text between custom added HTML Tags

I have he following scenario:

Got an HTML template file that will be used for mailing.

Here is a reduced example:

    <table>
<tr>
<td>Heading 1</td>
<td>heading 2</td>
</tr>
<PRODUCT_LIST>
<tr>
<td>Value 1</td>
<td>Value 2</td>
</tr>
</PRODUCT_LIST>
</table>

All I need to do is to get the HTML code inside <PRODUCT_LIST> and then repeat that code as many times as products I have on an array.

What would be the right PHP Regex code for getting/replacing this List?

Thanks!

Assuming <PRODUCT_LIST> tags will never be nested

preg_match_all('/<PRODUCT_LIST>(.*?)<\/PRODUCT_LIST>/s', $html, $matches);

//HTML array in $matches[1]
print_r($matches[1]);

Use Simple HTML DOM Parser. It's easy to understand and use .

$html = str_get_html($content);
$el = $html->find('PRODUCT_LIST', 0);
$innertext = $el->innertext;

Use this function. It will return all found values as an array.

<?php
function get_all_string_between($string, $start, $end)
{
    $result = array();
    $string = " ".$string;
    $offset = 0;
    while(true)
    {
        $ini = strpos($string,$start,$offset);
        if ($ini == 0)
            break;
        $ini += strlen($start);
        $len = strpos($string,$end,$ini) - $ini;
        $result[] = substr($string,$ini,$len);
        $offset = $ini+$len;
    }
    return $result;
}

$result = get_all_string_between($input_string, '<PRODUCT_LIST>', '</PRODUCT_LIST>');
