PHP Dom Remove Item Leave Content

I am trying to remove specific links based on their ID tag, but leave the contents of the link. For example, I want to turn

Some text goes <a href="http://www.domain.tdl/" id="remove">here</a>

to

 Some text goes here

I tried using below.

 $dom = new DOMDocument; $dom->loadHtml(mb_convert_encoding($html, 'HTML-ENTITIES', "UTF-8")); $xp = new DOMXPath($dom); foreach($xp->query('//a[contains(@id="remove")]') as $oldNode) { $revised = strip_tags($oldNode); } $revised = mb_substr($dom->saveXML($xp->query('//body')->item(0)), 6, -7, "UTF-8"); echo $revised;

crudely taken from here , but it just discards the same contents of $html .

Any idea on how I will achieve this?

What is my function for this:

 function DOMRemove(DOMNode $from) { $sibling = $from->firstChild; do { $next = $sibling->nextSibling; $from->parentNode->insertBefore($sibling, $from); } while ($sibling = $next); $from->parentNode->removeChild($from); }

So this is:

 $dom->loadHTML('Hello <a href="foo"><span>World</span></a>'); $a = $dom->getElementsByTagName('a')->item(0); // get first DOMRemove($a);

Must give you:

 Hello <span>World</span>

To get nodes with a specific identifier, use XPath:

 $xpath = new DOMXpath($dom); $node = $xpath->query('//a[@id="something"]')->item(0); // get first DOMRemove($node);

An approach similar to @netcoder's answer, but using a different loop structure and DOMElement methods.

 $html = '<html><body>This <a href="http://www.domain.tdl/" id="remove">link</a> was removed.</body></html>'; $dom = new DOMDocument(); $dom->loadHTML($html); $xpath = new DOMXPath($dom); foreach ($xpath->query('//a[@id="remove"]') as $link) { // Move all link tag content to its parent node just before it. while($link->hasChildNodes()) { $child = $link->removeChild($link->firstChild); $link->parentNode->insertBefore($child, $link); } // Remove the link tag. $link->parentNode->removeChild($link); } $html = $dom->saveXML();

Using

  //a[@id='remove']/node() | //*[a[@id='remove']]/node()[not(self::a[@id=''remove])]

This selects all children of any a that have an id attribute with a value of "remove" , and all the previous and next siblings of that a that are not a by themselves, have an id attribute with a value of "remove"
