Kundi la Vitambulisho vya XML vilivyojumuishwa ndani katika PHP

Sasa hebu tuchukulie kuwa kuna vitambulisho vingi, ambavyo kila kimoja kina vitambulisho ndani yake:

test.xml<root>
  <tag>
    <elem>maandishi1</elem>
  </tag>
  <tag>
    <elem>maandishi2</elem>
  </tag>
  <tag>
    <elem>maandishi3</elem>
  </tag>
</root>

Tutapitia vitambulisho vyetu kwa kutumia kitanzi na kutoa thamani za vitambulisho vilivyomo ndani:

index.php<?php
  foreach ($xml->tag as $tag) {
    echo $tag->elem; // 'maandishi1', 'maandishi2', 'maandishi3'
  }
?>
