[Resolved] finding characters enclosed in HTML tags

[perpetualshaun]

Let's say that I have a string of text like this:

<strong>7pt.⁴ (130lb. T⁵/72lb. C⁶) Glossy^® Ultra gloss text cover</strong>

I would like to know how to find all the values of the text that falls between the sup tags and throw them into an array. Ideally, I would like to be able to create an array like this:

$footnote_array[] = 4;
$footnote_array[] = 5;
$footnote_array[] = 6;

Any ideas?

Thanks

probably would involve using regular expressions to match a string starting with ^{and ending with}

take a look at

and

or you could use explode();

 $t="<strong>7pt.<sup>4</sup> (130lb. T<sup>5</sup>/72lb. C<sup>6</sup> ) Glossy<sup>®</sup> Ultra gloss text cover</strong>"; 
$sups=explode("</sup>",$t);
foreach($sups as $val)
	{
	$bits=explode("<sup>",$val);
	if(!empty($bits[1]))
		{
		$footnote_array[] = $bits[1];
		}
	}
print_r($footnote_array);
