Use DOMXPath to exclude an array of tags

I am using: 

$dom = new \DOMDocument();
$xpath = new \DOMXPath( $dom );

to modify the DOM of my page.

I can exclude all elements that have an a tag using: 

$xpath->query( '//text()[not(ancestor::a)]' )

I would like to exclude a dynamic array of tags like:

$array => ['a', 'img', 'code'];

Is there a handy way to bundle these conditions?

It's just a question of iterative string building. Actually you can automate the iteration by using implode() for simple, indexed, flat arrays like yours:

$array => ['a', 'img', 'code'];
$xpath->query( '//text()[ not(ancestor::'.implode(') and not(ancestor::', $array).']'))

Should produce:

$xpath->query( '//text()[not(ancestor::a) and not(ancestor::img) and not(ancestor::code)]')
