PHP/regex: How to get the string value of HTML tag?

Question

I need help on regex or preg_match because I am not that experienced yet with regards to those so here is my problem.

I need to get the value "get me" but I think my function has an error. The number of html tags are dynamic. It can contain many nested html tag like a bold tag. Also, the "get me" value is dynamic.

<?php
function getTextBetweenTags($string, $tagname) {
    $pattern = "/<$tagname>(.*?)</$tagname>/";
    preg_match($pattern, $string, $matches);
    return $matches[1];
}


$str = '<textformat leading="2"><p align="left"><font size="10">get me</font></p></textformat>';
$txt = getTextBetweenTags($str, "font");
echo $txt;
?>

Answer 1

<?php
function getTextBetweenTags($string, $tagname) {
    $pattern = "/<$tagname ?.*>(.*)</$tagname>/";
    preg_match($pattern, $string, $matches);
    return $matches[1];
}

$str = '<textformat leading="2"><p align="left"><font size="10">get me</font></p></textformat>';
$txt = getTextBetweenTags($str, "font");
echo $txt;
?>

That should do the trick
