Hi Curt,

Thanks for your reply. So basically I do something like:

$doc = new DOMDocument();
$doc->loadHTML($file);

$p = $doc->getElementsByTagName('p');

How would then wrap the following around each <p> tag:

<form name="form" target="_parent"
action="/index.php?action=edit_paragraph&file='.$_GET['file'].'"
method="post">
<input type="hidden" name="old_html"
value="'.htmlentities($matches[0]).'">
<p><a href="javascript:;"
onclick="document.form.submit();">'.$matches[1].'</a></p>
</form>

BTW if its not obvious I am trying to create a CMS that lets users edit
anything within a <p> tag!
