body

I've want to match any occurrence of a search term (or list of search terms) within the tags of a document. My current solution uses preg (within a Joomla plugin)

$pattern = '/matchthisterm/i';
$article->text = preg_replace($pattern,"<span class=\"highlight\">\\0</span>",$article->text);

But this replaces everything within the HTML of the document so I need to match the tags first. Is this even the best way to achieve this?
