Style unstyled links with DOM and xpath

Question

For a system I am building I am defining a general style stored in LINKSTYLE that should be applied to a elements that are not yet sty

Answer 1

I was wondering if it's possible to solve this more CCS-wise, e.g. with a selector. In CSS3 it's possible to only address those tags that don't have the style attribute:

a:not([style]) {border:1px solid #000;}

So if your documents already have a stylesheet it could be easily added.

If not, then a testtest2

If the CSS clashes with other, higher selectors, this is not an easy solution. !important might help though.

HTML Fragment

And as far of getting the changed HTML fragment, this is some additional code that can work with gordons suggestion. Just the inner-html of the body tag, this time I played a bit with the SPL:

// get html fragment
$output = implode('', array_map(
  function($node) use ($dom) { return $dom->saveXml($node); },
  iterator_to_array($xpath->query('//body/*'), false)))
  ;

A foreach is definitely more readable and memory friendly:

// get html fragment
$output = '';
foreach($xpath->query('//body/*') as $node) 
  $output .= $dom->saveXml($node)
  ;
