How to delete a element by tag name with all elements inside it

Question

I want to use the dom removeChild function in php to remove everything between a tag.

my xml looks like

<root>
  <element>text</element>

  <remove>
    text
    <morexml>text</morexml>
  </remove>
</root>

Now I want to remove the tag including its entire inside. How do I do this? I do not have a clue. I am trying to use the only dom function i found: removeChild.

When removed it has to look like this:

 <root>
      <element>text</element>

 </root>

Is there a php dom function to do this? I can not find it on google or stackoverflow.

Answer 1

$dom = new DOMDocument;
$dom->loadXML($xml);
$dom->getElementsByTagName('root')->item(0)
   ->removeChild($dom->getElementsByTagName('remove')->item(0));

This is very specific, though. You can use XPath if you need more generality:

foreach ($xpath->query('//remove') as $node) {
   $node->parentNode->removeChild($node);
}

Answer 2

You can use XPath and delete over XPath the node.

Use DOM and XPath to remove a node from a sitemap file
