Removed all junk nodes in xml using php?

Question

Removed ALL junk nodes in xml using php

This is the sample input for the example:

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <!--comment1-->
    <elem>a</elem>
    <junk>b</junk>
    <elem>
        <!--comment2-->
        <junk>c<junk>d</junk></junk>
    </elem>
    <!--comment3-->
    <junk>e</junk>
</root>

This is the resulting XML:

<?xml version="1.0" encoding="UTF-8"?>
<root>

    <elem>a</elem>

    <elem>


    </elem>


</root>

I look documents and applied like this:

$doc = new DOMDocument();
$doc->loadXML($xml);
$xpath = new DOMXPath($doc);

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

for my case will remove all node "junk" and they will everywhere in xml document.

@python the accepted answer in my second link should work for you. Something like `$entity->deleteNodes('//entity[type="junk"]');` — Pekka, Dec 31 '10 at 16:09
